Overview:
KR-939S3 integrated three-parameter combination probe KR939SB3 is a non-bus structured general-purpose combination probe used by our company in the cooling tower fan safety monitoring system. It can be connected and used with a variety of general-purpose secondary instruments or computer data acquisition and control systems (DCS , PLC , etc. ) .
KR-939S3 integrated three-parameter combination probe KR939SB3 is a combination probe used for monitoring the safe operation of fan reducer. It integrates the sensing, conversion and transmission circuits for measuring oil temperature, oil level and vibration signals, and directly outputs 4 to 20mA standard current signals corresponding to these safety parameters. It can be connected to various general-purpose secondary instruments or computer digital acquisition monitoring systems.
