KR-939SB3三參數組合探頭 英文說明書上海驊鷹

KR939SB3 three parameter combination (oil level temperature vibration combination) probe is a general type combined probe that is used in cooling tower fan safety monitoring system. It can be connected with a variety of general two instruments, or computer data acquisition and control system (DCS, PLC, etc.).

This is applied to the fan gear box combined probe for safe operation of monitoring, in its internal integrated measuring temperature, oil level, vibration signal sensing, conversion and transmission circuit of direct output and the security parameters corresponding to the 4 ~ 20mA standard current signal, can be matched with a variety of general-purpose two meter or      computer digital acquisition monitoring system.

The probe temperature measurement with platinum resistance sensor and semiconductor integrated device; level measurement using a capacitive sensing principle; sensor for measuring      vibration, mechanical vibration acceleration signal acquisition, band-pass filter, an integral and true effective value through the amplifier (RMS) converter, the vibration waveform in the effective bandwidth of it effective value conversion; finally, the oil temperature, vibration generated by the 4 ~ 20mA output.

Main technical performance and indicators

• External and installation structures;

KR939SB3 three parameter combination probe, the probe is an external thread form, is installed in the threaded installation hole of the fan reduction box, and the probe rod is inserted into the reduction box, so as to get the lubricating oil temperature, the lubricating oil level and the box vibration signal in the reduction box, and complete the transformation output. Thread specifications and probe inserts need to be declared at the time of order. See Figure1.
