Series composition

·Diffuse silicon piezoresistive sensor: more economical, widely applicable for high, medium, and micro pressure measurements, most

The large measurement range is 0~35MPa, and the minimum measurement range is 0~1kPa.

·It has two types of electronic components: analog and intelligent. The analog component has an accuracy of 0.2% and a 10:1 range ratio. It can be adjusted on-site

Equipped with damping switch and intelligent HART communication protocol function, with an accuracy of 0.1%.

Working principle

Metal diffusion silicon piezoresistive sensor, pressure sensor is a type of semiconductor surface made by vacuum diffusion on a silicon substrate

The standard silicon piezoresistive strain bridge. It is separated from the measured medium by a layer of stainless steel corrugated sheet in the direction of the strain bridge

There is an intermediate fluid - silicone oil - filled between the stainless steel corrugated sheet. When pressure P acts on the corrugated sheet and passes through the intermediary

The liquid is transmitted to the strain bridge, and the change in bridge resistance causes the bridge to lose balance and output a series of voltage signals proportional to pressure

number. By amplifying the signal, the circuit is replaced with a 4-20mA output.

Installation Guide

Using the same connection method as a regular pressure gauge, the specific installation location is determined

Based on the requirements of the working conditions.

·Gas: higher than the pressure inlet

·Liquid: below or level with the pressure inlet

·Steam/water vapor: below the pressure inlet (it is recommended to use a circular device)
