Production of more than one million pressure transducers and transmitters per year
KELLER is certified according to ISO 9001:2008

KELLER AG für Druckmesstechnik, headquartered in Winterthur (Switzerland), is Europe’s leading manufacturer of isolated pressure transducers and transmitters. The company, which has a global workforce of around 400 employees, was founded in 1974 by Hannes W. Keller, a graduate in physics and the inventor of the integrated silicon measuring cell. The entire value creation, from production of the individual parts and calibration of the sensor through to the final inspection of the finished products, takes place at the headquarters in Winterthur. All KELLER AG products are therefore “Made in Switzerland”.

KELLER AG piezoresistive pressure sensors have impressively high precision and pressure ranges from 5 mbar to 2000 bar. In addition to more than 500 standard products, the company also develops and produces numerous customised solutions. Using state-of-the-art, automated manufacturing processes, large runs of industrial OEM transducers as well as special design versions in very small quantities are produced in more than 35 highly-specialised machining islands, resulting in more than one million pressure transducers and transmitters per year. The high quantities mean that we can keep prices low despite complex production processes and stringent quality requirements.

The KELLER AG product range includes digital manometers, level probes, data loggers, remote transmission units and pressure calibrators. Digital display equipment completes our wide range. The application areas for our pressure transducers are just as broad as our product range. For example, they regulate the internal cabin pressure in aircrafts, ensure the smooth switchover from natural gas to petrol in hybrid vehicles and are used as reference sensors in laboratory technology. KELLER special sensors, such as modular pressure catheters and other miniature transducers, are especially popular among researchers.

KELLER AG für Druckmesstechnik, including KELLER Ges. für Druckmesstechnik mbH Jestetten, is certified to ISO 9001:2008. The traceability of the measurement variables to national standards is therefore ensured.

Programmable Level Pressure Transmitter
digitally compensated

Series 36 X S (stretto line)

/ rangeable / digital and analog output

This pressure transmitter is designed for level measurement in narrow downhole applications
where highest accuracy is required.
- Only 16 mm diameter

Product Benefits:

- Mathematically compensated
- Programmable, assisting inventory reduction
- Filtering function 2 ms...30 sec
- Improved surge protection
- Bus-system capabilty (up to 128 transmitters)

36 X S level transmitter is available in two different versions:
• PAA-36 X St

Absolute Pressure, Zero at Vacuum

This probe is applied when the atmospheric pressure is measured by a separate barometer and
when the water level is calculated as the difference between the absolute value and the ambient
pressure. Venting of the electrical cable to atmosphere does not have to be considered for these
installations.
• PR-36 X St

Relative Pressure, Zero at ambient Pressure

This probe is fitted with a durable cable with an integral vent tube to the atmosphere. To prevent
the formation of internal condensation caused by installations in cold water on warm, humid
days, it is important to ensure only dry air enters the transmitter enclosure via the vent tube. If
the vent tube is not terminated in a warm, dry enclosure, KELLER recommends and can supply a
purpose built cartridge filled with a silica gel which is fitted at the end of the reference tube.
Programming
With the KELLER software READ30 and PROG 30, a RS485 converter (i.e. K-102, K-104 or
K-107 from KELLER) and a PC (Laptop), the pressure can be displayed, the units changed,
and new gain or zero set. The analog output can be set to any range within the compensated
range.
