HTR Series – Split Core Current Sensors
The HTR Series split‑core current sensors are engineered for electronic measurement of DC, AC, and pulsed currents across nominal ranges from 50 to 500 A, with full galvanic isolation between primary and secondary circuits. Designed for industrial environments, HTR sensors combine measurement accuracy with mechanical simplicity.
HTR current sensors operate with a dual supply voltage of ±12 V to ±15 V and provide an instantaneous voltage output for real‑time current monitoring.
Unlike the HOP Series, the HTR product line is characterized by a fixed circular aperture of 21 mm, optimized for standard conductor sizes.
Its split‑core design supports fast, non‑intrusive installation, making the HTR Series well suited for industrial systems requiring straightforward current sensing with consistent mechanical integration.
