Cooling tower fan TSM803 three in one probe

Cooling tower fan TSM803 three in oneprobe

It is a non bus structured universal combination probe used in our company's cooling tower fan safety monitoring system. It can be associated withMultiple universal secondary instruments or computer data acquisition and measurement systems（DCSThePLCConnect and use.

This combination probe used for monitoring the safe operation of wind turbine gearboxes integrates sensing, conversion, and transmission circuits for measuring oil temperature, oil level, and vibration signals. 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; The oil level measurement adopts the principle of capacitive sensing; 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 (RMS) through an amplifier, bandpass filter, first-order integration, and RMS converter; Oil level, temperature, and vibration each generate 4-20mA output

• Electrical connection:

Due to the humid environment on site, the product is equipped with a 5-core double-layer shielded cable when leaving the factory, and the joint has been waterproofed. The corresponding relationship between cable wiring colors is as follows:

Red:+24V power supply;

Black: Public COM;

Cable shielding wire: grounded;

Brown: Vibration output;

Blue: Temperature output;

Gray: Oil level output;
