DR6431 Submersible Level Transmitter
DR6431 Submersible Level Transmitter
The DR6431 is EX-plosion proof level transmitter for use in hazardous areas, the water level sensor adopts piezoresistive pressure sensor with high stability and reliability, which could measure liquid static pressure that is positive proportional to level depth precisely, and transform pressure signal into standard current/voltage signal output by amplifier circuit to measure accurate level depth. LCD display indicates level in inches, centimeters or percent of span, which make the water level sensor to read the liquid depth in real time. and the shell is explosion proof, which is shock resistant and damping, and stable for various harsh environments
