Introduction
The GXPS420 Series pressure transmitter is a highly reliable, high
stability, high precision,
high-temperature liquid level transmitter. Mainly used for the
measurement of high temperature
fluid level. This product uses 1Cr18Ni9Ti stainless steel
structure, import the internationally
famous brand of diffusion of oil-filled pressure core body ,
dedicated to zoom in and V / I
transmitter conversion circuit, and can facilitate to calibrate its
zero and full scale.
According to different use of site configure wear, oil, acid and
alkali resistant, high strength special
breathable cable. Two-wire system circulation output leads
non-polarity, three-wire voltage output for
AC and DC. The security proof, isolation, explosion-proof
certification and CE certification.
