KR939SB3 three in one probe

KR-939SB3 integrated three parameter (oil temperature, oil level, vibration) combination probe is a universal non bus structure combination probe in the KR-939 series cooling tower fan safety monitoring system. It can be directly connected to the "KR-939B3 Fan Safety Monitor" to achieve single device monitoring. It can also be connected to various general-purpose secondary instruments or computer data acquisition and control systems (DCS, PLC, etc.) for 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.

KR-939SB3 three parameter combination probe features:

Probe temperature measurement uses platinum resistance sensors and semiconductor integrated devices; The oil level measurement adopts the principle of thermal conductivity sensing; The magneto electric sensor used for vibration measurement can directly obtain the velocity signal of mechanical vibration. After passing through an amplifier, bandpass filter, and true RMS converter, the complex vibration waveform within the effective bandwidth is converted to true RMS. Finally, the voltage/current drive circuit generates a 4-20mA output.
