Current sensors, 360 amps and 1800 amps to measure current in traction motor control applications

Used for applications where current needs to be measured, TMV’s Current Sensors allow for the accurate measurement of current through the cable-hole—without the need to modify existing wiring.
Reinforced and robust, TMV’s Current Sensors can withstand a lifetime of transportation shock and vibration without jarring components.

Additionally, for wheel-slip control, current sensors are a viable alternative to Axle Generators or Speed Probes, as current and voltage can be calculated to monitor traction and wheel-slip conditions.

These current sensors are typically connected to a TECU system, providing a wealth of current information utilized to monitor and control the locomotive.
