IMP+ Pulsar Ultrasonic Level Sensor

IMP+ Pulsar Ultrasonic Level Sensor
IMP+

IMP+ can be used wherever you need reliable non-contacting ultrasonic level measurement and digital echo processing means IMP+ is perfect for slurries or liquids and anywhere you need a display telling you the level, or an analogue output to interface with your site control system or drive a display.

There is an IMP+ ultrasonic level sensor to suit your application, 3m, 6m and 10m range versions are available and each can be wired for 2-wire and 3-wire operation. IMP+ features a LCD display and digital temperature measurement and compensation. IMP+ also has 2 relay outputs as standard.
