KELLER Pressure Sensors – Developed for Harsh Environments
Materials
All materials, from acid gas-resistant Hastelloy to high-strength Inconel for extreme pressures, were chosen to meet the chemical and mechanical demands of the oil and gas environment.
Housing
KELLER pressure sensors are laser-welded and are situated in a hermetically sealed housing. The laser-welded housing produces a smooth, seamless join and prevents corrosion and media penetration. The hermetic seal ensures years of protection for the pressure sensor chip, even with permanent exposure to aggressive fluids, pressure cycling and thermoshocks.
Media
Thanks to their housing design, KELLER pressure sensors offer lasting resistance to the full spectrum of aggressive media* that can be present in upstream, midstream and downstream applications.
*H₂S, CO₂, brine, drilling mud, hydrocarbons
Long-Term Stability
KELLER Pressure is one of the leading pressure sensor manufacturers and has longstanding experience in permanent monitoring applications throughout the energy sector. Thanks to high-quality, coordinated components – from the pressure sensor chip to the optimum oil volume to the housing – our products guarantee unrivalled long-term stability.
Repeatability & Process-Critical Control
KELLER pressure sensors provide consistent measurement results, even with fluctuating pressures and temperatures. This consistency is vital for stable control loops, safety-critical decisions and long-term optimisation of drilling, pump and refinery processes.
Mathematic Model
Sensor behaviour is modelled and adjusted through precise calibration of the KELLER pressure sensors. They therefore offer stable, reliable performance throughout the life cycle, even under changing temperature and operating conditions.

Flexible Integration Options
Maximum precision is achieved through a combination of the unique mechanical design and the optimally coordinated electronics. The pressure sensors can be supplied with or without integrated electronics. The full mathematic model is directly incorporated in the device or in-house custom signal processing hardware can be used. In this case, KELLER Pressure provides the full mathematic model data to ensure that the sensor behaviour can be accurately modelled, compensated and maintained throughout its lifetime.

Pressure Ranges From Vacuum up to 2000 Bar
Whether for monitoring low-pressure gas systems or for high-pressure hydraulic fracturing, KELLER pressure sensors provide precise, stable measured values across an extremely wide pressure range.
Temperature Ranges From -20 to 200 °C
KELLER pressure sensors are suitable for reliable operation in low-temperature to high-temperature bore hole and refinery environments. They cover a temperature range from -20 to 200 °C without losing accuracy and reliability.
Mathematic Model up to 180 °C
The mathematic model enables precise correction of temperature-dependent effects over the entire compensated temperature range up to 180 °C. In addition, KELLER pressure sensors function mechanically up to 200 °C, whereby in-house custom signal processing can be used if required.
Applications in the Oil and Gas Industry
Artificial lifting systems with high load and high temperatures (ESP –electrical submersible pumps)
KELLER pressure sensors are suitable for use in electrically powered pump environments in the bore hole. In applications involving thermal stress, pressure cycles and continuous mechanical stress, they ensure exceptional stability and reliable measurement results over the long term.
High-pressure and high-temperature environments (HPHT)
KELLER pressure sensors are suitable for extreme bore hold conditions, in which pressure and temperature are subject to strong fluctuations.
Dynamic hydraulic and pneumatic control systems
KELLER pressure sensors are suitable for systems requiring rapid, stable reaction under continuous mechanical stress.
Environments with high chemical or corrosive stress
KELLER pressure sensors are suitable for environments exposed to aggressive media such as acid gas, brine solutions and chemically active liquids.
Monitoring systems with long-term monitoring
KELLER pressure sensors are ideal for systems permitting long-term stability and only minimal deviations.
Deep waters and environments with high external pressure
KELLER pressure sensors are suitable for systems that are subject to extreme hydrostatic external pressure.
Safety-critical pressure control loops
KELLER pressure sensors support stable, repeatable measurements for safety and shut-off systems.
Long-term operational safety and low maintenance in hard-to-reach locations
KELLER pressure sensors are ideal for environments with limited maintenance access. Their high quality and long lifetime mean maintenance efforts and costs are reduced to a minimum.
