New in Our Standard Product Range
Typical fields of application are food and pharmaceutical industries as well as general mechanical engineering with compressors and mobile units.
The V i b E x G a u g e is recommended wherever operating conditions exceed the requirements of the basic standard.

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
With its luminous yellow color, 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.

Available Devices
- Pressure gauges
- Thermometers
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.

How about a thermometer with individual design?
Supplementing our industrial ambient thermometers, the TRCh 100 is now also available for private use.
The instrument with high-quality stainless steel case is weatherproof and reliably indicates the temperature both indoors and outdoors. Using the latest technology, we are able to design your customised thermometer. We can implement individual dials with your colour requirements, also combined with your text elements.

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.
- 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
- 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
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.

There are measuring points at which extremely high overpressures do occur. For this purpose, our new diaphragm pressure gauge PCh 100 – 3 HOP is applicable. Depending on the pressure range, the instruments can withstand overpressures from 100 to 600 bar.
The specific requirements have to be coordinated with our solution possibilities. Options, which are available for “regular” diaphragm pressure gauges, are basically also possible here. Details also have to be specified, e.g. open connection flange, limit switch contact assembly.

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.

Especially for Arctic countries, where outside temperatures can drop to −60 °C (−76 °F), we have now developed a safety pressure gauge that is able to brave such temperatures…
Our RSChgG 160 – 3v does not only withstand extreme temperatures down to −60 °C (−76 °F), but also sandstorms, salt water or sea air. This pressure gauge can also be used in explosion hazardous areas.

The PTC coating is also approved for use in the food industry.
PTC coatings enhance the mechanical properties of stainless steel chemical seals and increase the service life in case of difficult media. With the PTC coating on our High-Soft Membrane, no measurable additional errors occur. In-line seals and flange-type chemical seals with extension tube are also ideally suited for PTC coatings. PTC coatings of special materials upon request.

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.

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.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.
