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.
