According to the requirements of technical specifications such as "rules for the application and maintenance of train operation monitoring device (LKJ)" and "JJG (railway) 181-2004 test equipment for train operation monitoring and recording device", the spa-type locomotive speed system detector simulative outputs the sensor speed pulse that conforms to the provisions of the railway standard "TB/T 2670-2010" on the sensor pulse signal.Wheel diameter and speed can be set arbitrarily within the range of technical parameters.

Technical indicators:

◆ Environmental temperature: -20~70℃
◆ Work Power: ≥9VDC
◆ Work Current: ≤20mA(no-load)
◆ Detection sensor pulse number per revolution: 50~400P/R
◆ Detection wheel diameter range: 500~1300mm
◆ Simulation speed range: 0~350km/h
(Internal combustion 1050, electric power 1250, bullet train 845/935, etc)
◆ Output frequency range: 0~15kHz, Accuracy: 5‰
◆ Output pulse amplitude: high level>9V,low level<0.5V

Characteristics:

◆ Detector design compact, can be directly screwed on the sensor connector socket, easy to operate
◆ It has overvoltage and overcurrent protection to prevent abnormal damage of equipment
◆ The output signal has high precision and good stability
