- Clearly visible slanted LED display
- Two-colour display of the process values to identify the acceptable range
- Easy installation with integrated mounting holes and accessories
- Two switching outputs, one of them programmable as analogue output
- Pressure range -1...1 bar or -1...10 bar
The PQ series pressure sensors are designed to monitor system pressure in pneumatic and compressed-air networks of machines and plants. The sensors can be used for both relative and differential pressure measurement. This makes them particularly suited for monitoring of filters for soiling or clogging.
The measuring cell is insensitive to liquids or deposits that might occur in the system. It is overload protected and highly accurate.
A 4-digit LED display, which can be seen from a distance and easily read, and two pushbuttons allow easy set-up, maintenance and operation of the sensor. The display can be switched from the indication of “red” to an alternating indication of “red – green”. So, switching states can be highlighted or an independent colour window can be created.
Sensors with analogue output can also be configured via IO-Link, e.g. using a USB interface. The LINERECORDER SENSOR software is used to visualise, transfer and archive parameter sets.
