Description
- Very low in maintenance through non-contact measurement
- Extremely versatile thanks to measurement ranges from 0.07 m to 40 m
- Protection IP 68
- ATEX approval for Ex-Zone 0 and 1
- Alarm output in case of flooding possible
- Resistant to moisture, aggressive environments and heavy temperature fluctuations
The ultrasonic sensors with integrated temperature compensation for connection to NivuMaster- Series evaluation units provide a wide variety of measuring options for liquids.
The sensors provide accurate and reliable readings even in narrow tanks, no matter what measurement range or application. False echoes reflected from built-in obstructive constructions are negligible since they will be avoided automatically.
The sensors are available with 1"-thread or as flange version according to DIN and thus can be installed without any problems.
Typical applications for P-Series sensors
- Level measurements in the water and wastewater sector
- Flow measurements in open flumes and weirs
- Volume measurements in tanks
- Comparative measurements on screens
- Pump control in pump stations
