Pressure transmitters for continuous measurement in liquids and gases
Absolute and gauge pressure continuous measurement provide the safe measurement of liquids and gases in various applications. With a wide range of materials and approvals available to suit any installation environment such as hygienic, SIL and explosion protection certification. Feel free to contact us to discuss your application further.
Absolute and Gauge pressure measuring principle:
Silicon cell: The operating pressure deflects the process isolating diaphragm and a fill fluid transfers the pressure to a resistance bridge. The pressure-dependent change in the bridge output voltage is measured and evaluated.
Benefits:
- For process pressures up to 700bar (10,500psi)
- For process temperatures from -70 up to +400°C
- Flush mount process connections available
- Guaranteed overload resistance
- Diaphragm seals in wide range of materials and process connections

Continuous level measurement in liquid applications with pressure sensors
Be it water or any other liquid, hydrostatic level sensors measure in various applications in all industries like food, water and wastewater. The hydrostatic sensors offer the right solution in tanks or wells, submersible or installed outside a vessel. Contact us to learn more about the broad range of hydrostatic level sensors to suit your application.
Hydrostatic level measuring principle:
The process pressure acts directly on the robust ceramic process isolating diaphragm and deflects it. A pressure-dependent change in capacitance is measured at the electrodes of the ceramic substrate and the process isolating diaphragm.
Benefits:
- Robust ceramic sensor for excellent abrasion and chemical compatibility
- Suitable for vacuum applications
- Integrated membrane breakage detection
- Simple commissioning

Continuous level and differential pressure measurement
Electronic differential pressure is used to measure the pressure of level, volume or mass of liquids in pressurised tanks or distillation columns/evaporators. Using two ceramic sensors and one transmitter, the electronic dp system eliminates issues of traditional differential pressure measurements. Simplified installation and reduced maintenance requirements therefore reducing overall costs.
Differential pressure measuring principle:
The ceramic sensor is an oil free sensor. The process pressure acts directly on the robust ceramic process isolating diaphragm and causes it to deflect. A pressure dependent change in capacitance is measured at the electrodes of the ceramic substrate and the process isolating diaphragm. The measuring range is determined by the thickness of the ceramic process isolating diaphragm.
Benefits:
- Eliminates traditional mechanical issues with oil filled capillaries and seals
- Lower cost of ownership due to reduced installation time, maintenance and spare parts
- Multivariable measurement, head pressure, level, temperatures from one system
- Overload resistance high purity ceramic sensor
- Self-monitoring for continuous device health
