Honeywell SLN700 SmartLine Non-Contact Radar

The Honeywell SLN700 is a high performance 80 GHz non-contact radar level transmitter offering high accuracy, stability over a wide range of level applications. This transmitter is an ideal solution for demanding process level needs, with easy-to-use and low-maintenance character.

The SmartLine 80 GHz Non-Contact Radar Level transmitter utilises Frequency Modulated Continuous Wave (FMCW) technology which has greater sensitivity and accuracy for level measuring applications.

Honeywell SLN720 ​SmartLine Level Transmitters are used in applications where technologies such as capacitance, hydrostatic level or ultrasonic level measurements may have been used earlier. Immune to changes in conductivity, density, pressure and temperature, the level meters offer better reproducibility and accuracy than these other technologies. Since the signal travels up and down the probe, it is also unaffected by the angle of repose of a granular material.
