LFW70 Explosion-Proof Temperature Transmitter
PRODUCT FEATURES
Description
LFW70 Explosion-proof Temperature Transmitter adopts imported A-class platinum resistor,importedhigh-precision ADC and reference.These components have been carefully calibrated and debugged toprovide a standard temperature analog signal and digital signal output.It uses stainless steeltemperature probe rods and aluminum alloy shell,which has good stability and mechanical strength.There are multiple output options of voltage,current,HART and RS485,can be widely used intemperature measurement for petroleum,chemical,power station,hydrology and other industrial field.
