Huatian Diffused Silicon Transmitter Gas, Liquid Hpm135 Wireless Pressure Transmitter

Product Description

CYB4500 series oil-water well explosion proof china air digital lora wireless pressure transmitters

Product Description

Introduction

This wireless pressure transmitter belongs to the supporting product of oil-water well wireless monitoring system, and is suitable for pressure monitoring during production, storage and transportation process of oil-water well. Adopts micro-power wireless communication mode, no wiring required, so installation becomes quicker, safer and more convenient. In addition, there are matching wireless adapters that can convert many wireless pressure signals into MODBUS standard signals for transmission via Ethernet or serial port, which can help to access measurement control system more convenient and has a wide range of applications.

Working Principle

The sensing element of this wireless pressure transmitter is a diffused silicon pressure sensor, and the Lora module is used for wireless communication. The sensitive chip uses integrated circuit technology to make a sensitive piezoresistance on a crystalline silicon wafer to form a wheatstone bridge as a sensitive device for force-electric conversion. When an external force is applied, the bridge loses its balance. When a constant current excitation power is applied to the bridge circuit, the pressure signal can be linearly converted into a millivolt-level voltage signal, amplified into a digital signal, and then sent by a wireless module to a host computer.
