Display type pressure transmitter

I. Product introduction

RST2088 economic pressure/liquid level transmitter is assembled by high-precision and high-stability chip with imported stainless steel isolation diaphragm. The product is manufactured through precise structural design, reasonable temperature compensation, linear treatment circuit, V/1 conversion and all-seal welding technology of stainless steel shell. Output signal 4 ~ 20mA, 1 ~ 10mA, 0 ~ 5VDC. The product can be used to measure the pressure of gas, liquid and vapor and the pressure of corrosive medium. According to the need, can be equipped with linear 100% pointer head or digital display head.

Ii. Product application

This product is widely used in water plants, oil refineries, sewage treatment plants, building materials, light industry, machinery and other industrial fields, to achieve the measurement of liquid, gas, vapor pressure.
