Three parameter combination probe KR939SB3

This combination probe for monitoring the safe operation of wind turbine gearboxes is integrated internallySensing, conversion, and transmission circuits for measuring oil temperature, oil level, and vibration signals, directly outputting these safety parametersThe 4-20mA standard current signal corresponding to the quantity can be connected to various general-purpose secondary instruments or computersDigital acquisition and monitoring system.Probe temperature measurement uses platinum resistance sensors and semiconductor integrated devices; The oil level measurement uses heatGuiding sensing principle; Magnetic electric sensors used for vibration measurement can directly obtain the velocity of mechanical vibrationThe degree signal is amplified, bandpass filtered, and transformed into a true effective value (RMS) converter within the effective bandwidthThe complex vibration waveform undergoes true effective value conversion, and is ultimately driven by a voltage/current circuit to generate 4-20mAOutput.The combination probe is a small integrated all stainless steel anti-corrosion structure, and the output transmission method has long line resistanceInterference capability, coupled with good sealing and seismic/explosion-proof measures, enables it to withstand harsh environments on measurement sitesLong term online work.
