100kPa 28VDC Piezoresistive Differential Pressure Transmitter With G1/4 Female Thread

SPT90 Piezoresistive Differential Pressure Transmitter

Features

·Full stainless steel construction, compact size, easy installation;

·Using piezoresistive differential pressure sensor, 316L isolated diaphragm;

·Temperature compensation and aging, stable performance;

·Zero and span adjustable outside;

Introduction

SPT90 uses piezoresistive differential pressure sensor as sensing element. Silicon oil is filled in between die and two diaphragms, when measured differential pressure is added on two diaphragm, the pressure could be transferred onto die through silicon oil. Sensor die connects with amplifier circuit through wires, using semi-conductor’s piezoresistive effect, transforming differential pressure signal into electric signal. The whole product is used for differential pressure measurement of petroleum, chemi-industry, power station and hydrology, etc.

Order Note

1. We suggest to install tri-valve between the measured point and transmitter to protect the media adding on transmitter’s positive and negative cavities slowly;

2. We suggest to make two pressure ports horizontally to reduce installation direction effect;

3. Please pay attention that the static pressure should be less than 20Mpa, transmitter positive and negative cavity should be in the rating pressure range;

4. If the user has special requirement, please feel free to contact our company.
