ECVS Series Dual-channel Speed Sensor for Electrically-Conductive Wheels
ECVS series dual-channel speed sensor is based on the principle of eddy current (non-magnetic), it is suitable in conjunction with an aluminum pole wheel (or other conducting, non-magnetic metal) for generating two nominally 90° phase shifted square wave signals indicating the rotary speeds and the direction of rotation.
This dual-channel speed sensor uses light-weight target wheels made of aluminum alloy for its weight-saving construction, and the free-maintenance is ensured since that the measuring surface does not attract magnetic particles such as ferric powder or swarf. The speed sensor is ideal for operation in presence of ferric particles due to non-magnetic measuring system.
Yuanben provide customized and standard speed sensors for automotive, railway, power and industrial applications.
- Maintenance and wear-free operation due to non-contact measurement of rotation
- Safe detection of slow rotation from 0 Hz without pulse loss and for high-speed rotation up to 25 kHz
- Suitable for electrically conducting target wheels
- Two channels shifted by 90° provide the direction of rotation
- Robust and compact stainless steel housing suitable for harsh application
- Simple flange mounting
- Customized cable fittings
- Rail vehicles: traction control, anti-slip, motor speed, anti-skid
- Automation: measurement of speed and positions at gears, motors and roller
