  • PCM3051S-LT, RD intelligent flange pressure and differential pressure transmitter

PCM3051S-LT, RD intelligent flange pressure and differential pressure transmitter

■ Metal capacitive sensor adopted
■ Wide pressure range covering 0-0.2kPa~40MPa
■ Double-wire mode, 4~20mA analog output,

HART® protocol digital communication option
■ Intelligent LCD gauge outfit with backlight
■ With both the remote transmission and the local zero

and pressure range adjustment
■ Complete varieties, high accuracy, good stability,

adjustable damping, and strong resistance to

the unidirectional overpressure
■ Ex-proof housing structure, strong resistance to 

the frequency conversion interference
■ Without mechanical transmission component,

firm and shockproof
■ The price is cheaper than that of similar

imported instruments
