Main functions and technical parameters

●K1-KR-939SB3Type IntegrationThree parameter combination probeThe external thread form is installed in the threaded hole on the upper part of the fan gearbox (or other tested equipment), and the probe is inserted into the gearbox to obtain the lubricating oil temperature, lubricating oil level, and box vibration signal in the gearbox, and complete the transmission output.
●Temperature measurement characteristics:Lubricating oil temperature measurement range: 0-100 ℃, comprehensive temperature measurement error: ± 3 ℃
●Oil level measurement characteristics:Lubricating oil level measurement range: -10~40mm, comprehensive error of oil level measurement: ± 5mm (0mm is the oil limit position below the normal oil level of the gearbox, and the measured medium must be non-conductive)
●Vibration measurement characteristics:Vibration measurement range: 0-20mm/s, measurement output is proportional to the true effective value (RMS) of vibration velocity, vibration measurement frequency band range: 10-1000HZ, comprehensive vibration measurement error: ± 1mm/s
●Signal output characteristics:Current type output: DC/4-20mA, maximum load resistance calculation (including transmission line internal resistance) Rmax=（V-15)/0.02 (includingVFor power supply voltage)
●Power supply characteristics:Recommended working voltage: DC/24V ± 2V, no-load working voltage: DC/15V, maximum overload voltage: DC/36V, maximum instantaneous working current: 200mA, with built-in voltage polarity reversal protection
●Environmental characteristics:Environmental temperature range: -20~80 ℃, environmental humidity range: 0~100% (port sealed with 704 silicone rubber), environmental vibration conditions: not less than 3 times the upper limit of the vibration range.
