Kotron® Model 82 Rf Capacitance Level Transmitter
Kotron 82 2-Wire RF capacitance transmitter is one of the most cost-effective level transmitters available today. Compact in size, it employs state of the art technology for a stable, accurate signal in a wide range of materials.
The Kotron® Model 082 transmitter is one of the most cost-effective level transmitters available today. Compact in size, it employs state-of-the-art surface mount technology in an encapsulated module for a stable, accurate measurement.
Operating Principle
As media rises and falls in the tank, the amount of capacitance developed between the sensing probe and the ground reference also rises and falls. This change in capacitance is converted into a proportional 4-20 mA output signal.
Applications
- Continuous level monitoring
- Liquid-liquid interface level measurement
