In many pressure measurement applications it is necessary to clean the pressure ports from dust or blockage.
The PM8 Purge Module is designed to be connected between sensors and pressure taps and makes it possible to apply purge pressure to the measurement openings.
The internal valves are controlled by a micro-controller. When a purge operation is triggered, first the sensors are disconnected from the pressure taps. After that, the internal high pressure valve is activated and routes the purge pressure to the taps.
To avoid a pressure kickback into the sensors in case of a permanent blockage of the measurement line, the high pressure valve is closed and the purge pressure is relieved before the sensors are reconnected to the measurement lines. This protects the sensors from overpressure due to a possible purge pressure kickback.
The device has the following properties:Purge pressure up to 6 bar (87 PSI)
- Flexible trigger options: Manual, digital, RS232, RS485, CAN
- Sensor protection by automatic pressure relieve
- Simple installation
