Three axis vibration probe temperature sensor

Three axis vibration probe temperature sensor

Introduction

Three axis vibration probe temperature sensor, is a non bus structured universal combination probe used in our company's rotating machine safety monitoring system. It can be connected to various general-purpose secondary instruments or computer data acquisition and control systems (DCS, PLC, etc.) for use.

This combination probe for monitoring the safe operation of rotating machines integrates sensing, conversion, and transmission circuits for measuring temperature, X, Y, and Z direction vibration signals inside. It directly outputs 4-20mA standard current signals corresponding to these safety parameters and can be matched with various general-purpose secondary instruments or computer digital acquisition and monitoring systems.

Probe temperature measurement uses platinum resistance sensors and semiconductor integrated devices; A sensor used for vibration measurement, which directly obtains the acceleration signal of mechanical vibration, and converts the vibration waveform within the effective bandwidth into true effective value through amplifiers, bandpass filters, and converters; The final temperature and three-axis vibration each generate 4-20mA output.
