Powertek Current Sensors

Current Sensors - Powertek | Westek ElectronicsThe CTHR current sensors convert ac, ac+dc and dc currents to a dc level proportional to the A rms. The CTHR sensors have excellent tolerance for distorted and complex wave shapes.

The CTHR sensors can provide all popular process control voltage and current loop outputs along with custom output options. A range of through hole or split core sensors means that connection is possible without shutting down manufacturing plants. Optional offset control allows nulling of residual ac currents to ensure best use of the output span (CTHR). The sensor power input is designed to operate over a wide voltage range associated with process control and sub-station auxiliary dc supply systems.

Active Hall Effect sensor technology allows measurement from DC-100kHz, depending on the core type selected. Typical applications are process control systems like PLC or SCADA, current monitoring in ac/dc drives, ultrasonics, welding and circuit breaker trip coils. For all CTHR models, a NIST/NPL (UKAS) traceable calibration certificate and certificate of conformance is supplied. All CTHR use UL or CSA approved materials.
