Level Transmitter

Switzer K 5750 SERIES RF capacitance type level transmitter provides a reliable and relatively low cost solutions to continuous level measurement of liquids or free-flowing granular products. Compact size and ease of installation combined with accurate sensing of level in both hazardous and non-hazardous locations renders this level transmitter the most versatile.

The amount of capacitance developed in any vessel is dependant on the surface area of the probe, the distance between probe and the ground reference, and the di-electric constant of the process medium. Considering that the probe's mounting position is fixed and the di-electric value of the medium is constant, the amount of capacitance developed between the probe and the ground reference increases and decreases as the medium rises and falls in the tank. The amount of capacitance developed can be varied by adjusting the combination of the probe diameter and length and its proximity to the ground reference. The change in level is recognised and convertered to an analog output signal (4 20 mA or 1 5V DC). The system will operate with standard 4 20 mA DC or 1 5V DC indicators. SWITZER also offers Digital Process and Loop Powered Indicators.
