Product Description

GHS1 series speed sensor General description

Series speed sensor is a device specifically designed to meet the needs of the rail transit vehicles operation. Based on the mechanism of the Hall effect, it provides stable and reliable signal for speed recording systems of rail vehicle such as traction system, braking system, monitoring system, etc. Sensor is usually installed on the housing or end enclosure of rotating device of all kinds of rail vehicles, and the measuring rotational object is a magnetic conductive speed-measuring gear.
