Bidirectional differential pressure sensors compare two pressures and return a signal that is proportional to the pressure difference.
The sensors offered here measure in a pressure range of ± x bar and are suitable for applications where negative and positive pressure must be measured alternately.
The range of bidirectional differential pressure sensors ranges from calibrated OEM sensors to high-precision amplified transmitters with standard output values.
Product overview
Analog OEM sensors*
- Compensated OEM pressure sensors with analog pressure output
- Compensated OEM pressure sensors with switching outputs and analog output
Digital OEM sensors
Analog/digital OEM sensors
* OEM sensors (original equipment manufacturer) are components that are still installed in a higher-level system (for example, by soldering to printed circuit boards)
PCB modules**
Transmitters***
Pressure transmitters wireless
- Pressure transmitter with bluetooth signal and battery powered
- Pressure transmitter with bluetooth and analog signal
** PCB modules (printed circuit board) are printed circuit board-mounted OEM sensors with additional industrial electronics for installation in a housing.
*** Transmitters are compensated, amplified and ready-to-use sensors with standardized output in a housing for direct installation
