Product Description Basic Info KR939SB3 three-parameter combination (oil level, temperature, and vibration combination) probe is a general type of combined probe that is used in the cooling tower fan safety monitoring system. It can be connected with a variety of general two instruments, or a 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 vibrationwaveform in the effective bandwidth of it effective value conversion; finally, the oil temperature, vibration generated by the 4 ~ 20mA output.PARAMETERS OF THREE-PARAMETER COMBINED PROBE KR-939SB3ITEMPARAMETERNOTEVIBRATION0-20MM/S LEVEL-10-40MM TEMPERATURE0-100oC OUTPUT4-20MA SENSOR LENGTH180MMCAN BE CUSTOMIZEDSENSOR DIAMETER12MMCAN BE CUSTOMIZEDCABLE LENGTH10 METERCAN BE CUSTOMIZEDTHREAD SIZEM27*2 Main technical performance and indicatorsExternal 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, stoget 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. Temperature measurement characteristic:Measurement range of lubricating oil temperature: 0~100 oC,Compreh-ensive error of temperature measurement:±1oCOil level measurement characteristics:Measurement range of lube oil level: 0~50 mm (10 mm for the gear box under normal oil level oil limit position), Maximum error of oil level measurement: <= ±1MMAmbient temperature from -40 to 65 C(Extreme temperature resistance from -50 to 150 C)Vibration measurement characteristics:Range of vibration measurement: 0~20 MM/s. The measurement output is proportional to the effective value of the vibration velocity (RMS). Frequency range of vibration measurement: 10~1000HZ, Maximum error of vibration measurement: <=±1MM/sSignal output characteristics:Active current type output: DC/4~20mA, Requirements for passive resistive loadMaximum load resistance:< 300 OhmSupply characteristics of the power supply:Working voltage: DC/24V±4V,Maximum protection voltage: DC/30V,Rated current: DC/80mA, Maximum instantaneous working current: 120mA,Internal voltage Ambient temperature range:-20~80oC,Ambient humidity range:0~100%(The port is sealed with 704 silicone rubber seals)Products Images: Use installation:KR-939SB3 integrated three-parameter combination probe is installed in the threaded hole on the upper part of the fan gearbox (or other equipment under test) in the form of external threads. The probe rod is inserted into the gearbox to obtain the lubricating oil temperature, lubricating oil level, and gearbox vibration signals in the gearbox, and complete the transmission and output.
