Overview

The design scheme adopts high-precision MEMS silicon piezoresistive sensors as the core, circuit digital compensation technology, and embedded software algorithms. While maintaining high accuracy and good linearity of the silicon piezoresistive sensor, it eliminates the problem of sensor zero drift, accurately displays small differential pressures, and outputs 4-20mA standard signals.

Product Details

Technical Specifications

1、 Product Introduction

The DW301 rail type micro differential pressure transmitter adopts a high-precision MEMS silicon piezoresistive sensor as the core design scheme, Dewey patented circuit digital compensation technology, and embedded software algorithm. While maintaining the high accuracy and good linearity of the silicon piezoresistive sensor, it eliminates the problem of sensor zero drift and can accurately display small differential pressures, outputting 4-20mA standard signals. The guide rail installation structure and blue ABS engineering plastic shell are sturdy, compact in size, and have the characteristics of high strength, light weight, and easy installation. Suitable for applications such as negative pressure ambulances, negative pressure wards, clean rooms, electronic factories, air conditioning unit filter monitoring, dust collectors, building automation, etc.
