Product Features

Using metal diffusion silicon sensors, it has wide applicability and is suitable for micro pressure measurement, vacuum measurement, and high pressure measurement

Quantity, high and low temperature, corrosion-resistant pressure measurement, and high cleanliness condition measurement, with analog and intelligent 0.1% high

Range ratio of digital linear temperature compensation, with HART communication protocol, inherently safe, and stainless steel casing

Suitable for clean environments.

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.

Electronic plug-in

Having two types of electronic plugins

Simulation type:4~20mA

Directly set the zero point, full-scale, and output damping at the measuring point through a potentiometer and toggle switch.

·Intelligent type: 4~20mA with HART protocol.

Set the zero point, full-scale, and output damping at the measurement point using two buttons and a toggle switch. In 4~20mA

Set at any point on the output line using the HART handheld DXR275.

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)
