KR-939SB integrated three-parameter integrated probe is a combined sensing and transmission unit that is applied to the safe operation monitoring of large and medium-sized rotary motion equipment such as cooling tower fans.
The probe is used in conjunction with the KR-939B fan safety monitor to perform on-line safety monitoring of the mechanical vibration during operation of the fan, the temperature of the gear box lubricant, and the oil level of the lubricant.
It integrates three sets of sensors, amplifiers and compensation transmission circuits into one. It uses digital coding technology to implement a four-wire bus connection method, that is, eight probes can be connected in parallel on a four-core cable, and up to 24 safe operation parameters of eight devices can be measured at the same time.
This product is particularly suitable for the safety monitoring of fan groups.
The main function and technical parameters
â—Temperature measurement characteristics: Lubricant temperature measurement range: 0 ~ 100 °C, temperature measurement synthesis error: ± 3 °C
◠Oil level measurement characteristics: Lubricant oil level measurement range: -10 ~ 40?, Oil level measurement comprehensive error: ±5? (0? is the lower limit of the normal level of the gear box, the measured medium must be non-conductive medium )
â—Vibration measurement characteristics: Vibration measurement range: 0 to 20 ?/s. The measurement output is proportional to the true rms value (RMS) of the vibration speed. The vibration measurement band range is 10 to 1000 Hz, and the vibration measurement synthesis error is ±1 ?/s.
â—Signal output characteristics: Command coded signal (D side): Logical pulse method, TTL level, measured signal return (A side): Temperature and level signal  DC/4~20mA, Vibration waveform signal  DC/12mA ±8mA (p-p), signal transmission distance: (probe to monitor) better than 500 meters
â— Power supply characteristics: Probe supply voltage (-V ~ +V terminal): DC/16 ~ 18V (provided by the monitor inside), single probe average supply current: 50mA, instantaneous zui large supply current: 150mA
â—Environmental characteristics: Ambient temperature range: -20～80°C, Ambient humidity range: 0～100% (Interface uses 704 silicone rubber seal)
