Original 316L SS differential diaphragm capsule Pressure Transmitter / đo áp suất sensor for Honeywell STG94L

pressure sensor

pressure sensor for Honeywell STG94L

Introduction
In 1983, Honeywell introduced the first Smart Pressure Transmitter the ST 3000®. In 1989, Honeywell launched the first all digital, bi-directional protocol for smart field devices. Today, its ST 3000 Series 900 In-line gauge Pressure Transmitters STG94L and the Series 900 Dualhead gauge (STG944), continue to bring proven “smart” technology to a wide spectrum of pressure measurement applications. Typical applications include high-pressure measurement in boilers, fuel feeds, and high pressure reaction vessels in the petrochemical and hydrocarbon recovery industries any location where accuracy and reliability are crucial to safe, economical operation. As with the rest of the line of Honeywell transmitters, the in-line
transmitters offer the ability to be installed in a wide variety of hazardous environments for accurate repeatable pressure measurement.

Description
The ST 3000 transmitter can replace any 4 to 20 mA output transmitter in use today and operates over a standard twowire system.
The measuring means is a piezoresistive sensor, which actually contains three sensors in one. It contains a differential pressure sensor, a temperature sensor, and a static pressure sensor.
Microprocessor-based electronics provide higher spanturndown ratio, improved temperature and pressure compensation, and improved accuracy.
The transmitter’s meter body and electronics housing resist shock, vibration, corrosion, and moisture.
