The IMP range of non-contacting level sensors from Pulsar Measurement are designed to be used wherever you need an accurate and reliable level indication. The unique digital echo process techniques featured in the IMP range of level sensors mean the units are perfect for slurries, liquids, or anywhere where you need a display giving you a level indication or analog output to interface with your existing site control system or to drive a display. 
 
There are several measurement ranges available from 200 mm to 10 m (7.9 in to 32.8 ft) and each sensor can be wired for 2 or 3-wire operation. All IMP options feature an LCD display and digital temperature measurement and compensation. Combine the IMP level sensors with PC Suite 4.0 and users will be able to download, analyze, and store echo profiles, set up the sensor parameters, install new firmware, and add a flow curve to configure level to flow linearization. 

• Compact self-contained level measurement
• Calibrate without compromising the IP67 rating
• Simple menu led set-up
• High power and narrow beam angles
