CSIS Series
Intrinsically-safe rf capacitance level transmitter
The CSIS Intrinsically-Safe Capacitance Transmitter is designed to detect the fluid levels of liquids in hazardous applications without the risk of ignition from a mixture of flammable and combustible materials in the air when a spark or heat is present. All models are equipped with durable, stainless steel enclosures and 316 stainless steel sensing probes. Output signals are available in 4-20 mA and 1-5 VDC, depending on the application. A variety of mounting sizes and probe lengths are made to order. The CSIS has suggested entity parameters to operate the sensor and is strictly used for intrinsically-safe platforms.
Technology
RF Admittance
The liquid acts as an isolator between two conductors (probe and tank wall). When level rises, there is more gain of capacity into an analog or digital signal.
