TCPP3 integration three parameters (oil temperature, oil level, vibration) combined probe, in the cooling tower fan safety monitoring system, is a non-bus structure universal combination probe. It can be directly connected with the fan safety monitor to realize the monitoring of single equipment. It can also be used with a variety of common secondary instruments, or computer data acquisition and measurement system (DCS, PLC, etc.).

This fan reducer is applied to the combination of the safe operation of the monitoring probe, in its internal integration respectively to measure the oil temperature, oil level, vibration signal of sensor, conversion and analog circuit, direct output and the security parameters corresponding to the standard of 4 ~ 20 ma current signal, can be allocated to various universal secondary instrument or computer data acquisition monitoring system.

The probe temperature measurement USES platinum resistance sensor and semiconductor integrated device; The thermal conductivity sensing principle is adopted for oil level measurement. Magnetoelectric sensor for vibration measurement, can directly obtain the speed of the machinery vibration signal, the amplifier, bandpass filter, true RMS (RMS) converter, the complex vibration waveform within the effective bandwidth, true RMS conversion, eventually produced by voltage/current drive circuit 4 ~ 20 ma output.

The composite probe can be obtained is closely related to the safe operation of the equipment under test of important parameters, so it is also suitable for other rotating machinery and reciprocation machinery equipment safety monitoring directly, is an essential part of modern industry, national defense, scientific research vibration safety monitoring unit.
