Geothermal Water Level Transmitter - CS-PT420

 1. Geothermal Water Level Transmitter CS-PT420 Product Description

The CS-PT420 series pressure transmitter is a high-reliability, high-stability, high-precision high-temperature-resistant level transmitter, mainly used for measuring the level of high-temperature fluids.

This product adopts a 1Cr18Ni9Ti stainless steel structure, with a diffusion oil-filled pressure core from an overseas brand, and a dedicated amplification and V/I transmitter conversion circuit, allowing convenient calibration of zero and full scale.

It can be configured with wear-resistant, oil-resistant, acid-alkali-resistant, high-strength special breathable cables according to different application sites.

Certified with intrinsic safety explosion-proof, isolated explosion-proof, and CE certification.

Two-wire loop output leads are non-polar, and three-wire voltage output type is AC/DC dual-use.
