TV6C pressure transmitter is two-wire system, high accuracy, smart capacitor pressure/differential transmitter, based on the core of advanced differential metal capacitor and micro processor, featured with high performance, good reliability, strong anti-jamming, overload performance etc.
The meter is widely used in many fields, such as petrochemical, metallurgy, power generated, environment protection, science development, machinery industry, military project, food service, pharmaceuticals, paper making, and textile industry, to monitor the parameters of differential pressure/pressure, liquid level, interface level, and density as well from fluid. If TV 6C can be used to monitor the fluid if matching with saving orifice.
TV6C series have kinds of function configurations through three buttons in enclosure and LCD . For instance, zero adjustment and full range adjustment in one-time, pressure or non-pressure to set range, easy switch among 20 display units. TV6S with big LCD screen is easy to read.
