Lumen Gauge

visible – even in complete darkness

The  L u m e n  G a u g e  version is designed to quickly and reliably identify whether the operating pressure of a process plant is within the normal range in case of insufficient lighting, at night or in the event of a sudden power failure.

For this purpose, the  L u m e n  G a u g e  is equipped with a luminescent dial, a reflective pointer tip and two adjustable reflective marks. When illuminated with a flashlight, the position of the pointer between the marks can be seen even at greater distances.

When charged with a flashlight, with ambient light or daylight, the dial will glow in the dark for a certain period of time. This glow effect is beneficial in safety-relevant and critical areas of a process plant allowing technicians to monitor the operating pressure while carrying out their maintenance tasks.

  • Luminescent dial
  • Black pointer with silver reflecting coating
  • Green reflecting marks
Available Devices
  • NCS 100 (4")
  • NCS 160 (6")
  • NCS 4½"
  • Also with case filling

Application Fields
  • Chemical plants
  • Crude oil and natural gas installations
  • Pipelines
  • Poorly lit plant interiors
  • Process equipment with areas difficult to access

Bright Dial

high contrast

The  B r i g h t  D i a l  is designed to increase the visibility of pressure gauges and thermometers in poorly lit environments.

With its luminous yellow colour, the measuring device quickly catches the eye in the installation. It also provides a higher contrast for easy reading. If the dial is illuminated with a lamp due to insufficient lighting, it is more visible than a white dial.

The  B r i g h t  D i a l  can also be used to distinguish between different process lines or to highlight measuring points of greater importance.

  • Dial luminous yellow

Available Devices
  • Pressure gauges
  • Thermometers
Application Fields
  • In low-light indoor spaces or process plants with areas difficult to access
  • Distinction between different process lines
  • Highlighting measuring points

Bourdon tube pressure gauge Hammer Union with chemical seal NPS 2" Class 15000

for pressure measurement on mud pumps on drilling rigs

Extremely difficult conditions prevail during drilling for and production of oil and natural gas so that pressure gauges have to meet highest demands regarding pressure, resistance against abrasion, impacts, shocks and vibrations. The liquid with the loose rock particles, which is transported to the surface by the mud pumps, is very abrasive and is extracted under high pressure.
The chemical seals that separate the pressure gauges from the medium have to be very robust, and the pressure gauge has to withstand the weather conditions, impacts and vibrations. Nevertheless, the measuring instruments have to operate with high accuracy and have to be easily readable, even from greater distances and under difficult weather conditions.
Besides the application in oil and gas production, there are also other fields of application, such as pumping of concrete or other highly abrasive media, which are transported in large pipelines under high pressure. Instead of a pressure gauge, the attachment of pressure transmitters is also possible.

Chemical seals with PTFE foil

cold pressed

Chemical seals are mounted when the medium must not come into contact with the measuring instrument. The application of chemical seals is inevitable especially for toxic and environmentally damaging media, or where corrosion resistance has to be ensured, but also when hygiene regulations require it. The most difficult measuring tasks can be mastered by using chemical seals with PTFE foil.

We have developed a new process – the KCT process – with which we are able to apply PTFE foil in a very thin, homogeneous layer. The process has no effect on the operating capacity of the chemical seal. Thanks to this new process, even difficult shapes (e.g. clamp chemical seals) can be coated with foil.

PTFE Properties
  • High chemical resistance (even with aggressive acids such as aqua regia)
  • Excellent anti-adhesive properties (extremely low surface tension)
  • Very good abrasion protection
  • Very good sliding properties
  • Physiologically safe
Improved Features with the KCT Technology
  • High temperature resistance from −40 °C to +260 °C (−40 °F to +500 °F)
    (please regard possible limitations due to the filling liquid)
  • Applicable up to 400 bar (5000 psi)
  • Highly vacuum-proof up to 260 °C (500 °F) – depending on the filling liquid
  • PTFE foils up to 0.5 mm (0.02") can be processed, with negligible influence on the measurement result
  • Difficult shapes can be coated with foil (e.g. clamp chemical seals)
  • Chemical seals made of special materials (e.g. tantalum) can be coated with foil

Diaphragm pressure gauge PCh 100 – 3 DG

for the sterile process technology

In order meet the special requirements for process connections, especially in the food and pharmaceutical industries, we have extended our standard product range.

All the wetted parts of our new diaphragm pressure gauge are made of stainless steel and are completely welded. Unlike chemical seals, here no filling liquid is necessary and we achieve an “absolutely dry measuring unit”. Contamination of the medium with the transfer liquid in the event of damage can thus be excluded. However, the diaphragm pressure gauge does not reach the lifespan of a pressure gauge with chemical seal. The temperature-related additional error of 0.8 % / 10 K in reference to the span is 6-times less favourable than for a pressure gauge with chemical seal.

Technical Data
  • Diaphragm pressure gauge with flush welded membrane
  • Bayonet ring case stainless steel
  • Nominal case size 100, 160 mm (4, 6")
  • Accuracy class 1.6
  • Pressure ranges 0 – 4 bar to 0 – 10 bar, also corresponding compound ranges
  • Overpressure 1.3 times full scale value
  • Permissible temperature
    • ambience −20 °C to + 60 °C (−4 °F to +140 °F)
    • medium −20 °C to +150 °C (−4 °F to +302 °F)
  • Data sheet 3202
  • DG – Dry Genic – dry measuring cell, no transfer liquid as in chemical seals
  • Flush welded diaphragm
  • Suitable for SIP and CIP, EHEDG-certified*
  • Process connections – like chemical seals, e.g. DIN 11 851, Tri-Clamp

* For clamp connections and process connections according to DIN 11 851, an EHEDG approval for the sealing is required.

Chemical seals extension tube type according to DIN, ASME and JIS

for particularly critical applications

The oil and gas industry imposes special requirements on all instruments connected to the process. Certain specifications, summarised in guidelines and defined in standards, have to be met. To be able to use these chemical seals in sour gas environments, the requirements according to NACE have to be complied with.

We have set ourselves the task of making our chemical seals with extension tube also applicable to those areas. The materials used are sour gas resistant according to NACE. We have solved the specifications regarding pressure resistance in accordance to the guidelines AD 2000, especially AD 2000 W2, by design and have reorganised our production. Moreover, we meet the special requirements on the weld seams (weld documentation, welding procedure tests) in accordance with DIN EN 15 613.

Besides the existing standards, we also comply with:
  • AD 2000 W2 for austenitic and austenitic-ferritic steels
  • AD 2000 W10 materials for low temperatures, e.g. −100 °C (−148 °F) PN 40
  • NACE MR 0175 only material with acceptance test 3.1 is used
  • Welding procedure according to DIN EN 15 613
  • Pressure ranges 25 mbar to 40 bar

Chemical seal with stainless steel extension tube and tantalum diaphragm

extending the application of chemical seals with extension tube

The industry is constantly faced with the task of having to work smoothly even with aggressive media – without the costs of measuring instruments getting out of hand.
Highly corrosion-resistant solutions are required, for example for urea. We offer high quality chemical seals with extension tube, the flush welded diaphragm is here made of tantalum.
This high-quality special material is more corrosion-resistant than regular stainless steel and can therefore meet even more specific requirements. Due to the applied non-positive welding process, which connects extension tube and diaphragm, no surface roughness occurs. This allows for the use of the chemical seals also in pharmaceutical applications.

  • Nominal pressure 16 / 40
  • Class 150 / 300
  • Data sheet 7502
  • Diaphragm more corrosion-resistant
  • Lower costs than with regular chemical seals with extension tube made of special material

Bimetal thermometers TBi

thermowells make it complete

The safety and functionality of temperature measuring points is determined to a large extent by thermowells. They protect temperature measuring instruments against mechanical and chemical stress and enable the replacement of thermometers without interrupting the process.
Bimetal thermometers are self-sufficient measuring instruments, which function without auxiliary energy. All cases, temperature sensors and process connections are made of stainless steel. Due to the hermetically sealed construction type and the materials used, they are perfectly suited for corrosive media and saline environments. In addition, many models are available with liquid damping.
All standard models can be readjusted with an externally accessible adjusting mechanism. Individual dials with luminous colour, customer-specific markings and special prints optimise the instruments for their specific case of application.
We recommend combining bimetal thermometers with one of the thermowells from our large range, which are perfectly suitable for most applications.

Diesel exhaust thermometers TA

thermowells make it complete

The safety and functionality of temperature measuring points is determined to a large extent by thermowells. They protect temperature measuring instruments against mechanical and chemical stress and enable the replacement of thermometers without interrupting the process.
ARMANO diesel exhaust thermometers are gas-actuated thermometers with a particularly robust, vibrationresistant construction. They are specially designed for measuring temperatures in exhaust and cooling lines of diesel engines. A highly viscous silicone oil ensures a constant good vibration damping of the indication. Due to the hermetically sealed construction and the materials used, diesel exhaust thermometers are also perfectly suited for deck and offshore areas. Models with capillary line allow for spatial separation between measurement and indication without the need for auxiliary power. Thus, the temperature values of inaccessible measuring points can be transferred to clearly visible or protected places.
