The KR-939SB integrated three parameter combination probe is a combined sensing and transmission unit used for monitoring the safe operation of large and medium-sized rotating equipment such as cooling tower fans.
This probe is used in conjunction with the KR-939B fan safety monitor, which can perform online safety monitoring of mechanical vibration, gearbox lubricating oil temperature, and lubricating oil level during fan operation.
It integrates three sets of sensors, amplifiers, and compensation transmission circuits internally. It uses digital encoding technology to achieve a four wire bus connection method, which allows eight probes to be connected in parallel on a four core cable, while measuring up to 24 safe operating parameters of eight devices.
This product is particularly suitable for safety monitoring of wind turbine groups.
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 lower limit position of 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: instruction encoding signal (D end): logic pulse mode, TTL level, measured signal feedback (A end): temperature
and liquid level signal DC/4-20mA, vibration waveform signal DC/12mA ± 8mA (p-p), signal transmission distance: (probe to monitor) better than 500 meters
Power supply characteristics: Probe power supply voltage (- V~+V terminal): DC/16-18V (provided internally by the monitor), average power supply current per probe: 50mA, instantaneous maximum power supply current: 150mA
Environmental characteristics: Environmental temperature range: -20~80 ℃, environmental humidity range: 0~100% (interface sealed with 704 silicone rubber)
