LEM launches high accuracy transducer for current measurement of trackside applications

LEM has introduced a new current transducer series, ideal for retrofitting trackside applications or for reducing the cost of new installations. Due to its robust design and standardized 4-20 mA out, it can also be used in automation or the control of PV-plants. The transducer’s innovative primary circuit (patent pending), in combination with two ASiCs to detect the magnetic field, enables precise current measurement.

The HTRS-series will be available in three current ranges (10 A / 30 A / 50 A), with peak current measurement up to twice that of nominal. Despite the very high insulation test voltage of 6.0 kV, the HTRS-series is compact, measuring 72 mm x 29 mm x 26 mm. The HTRS series also offers very good temperature stability, while mounting adapters allow the unit to be installed in existing applications.

The transducer complies with the International Railway Industry Standards (IRIS). With the HTRS, users in the field of railway technology have a versatile series of sensors at their disposal, regardless of whether they work in the field of rail or signalling technology. The HTRS series is suitable for measuring currents in point machines, crossing gates and signalling systems. It can also be used in industrial applications, such as process automation or DC current collection in solar parks (more info).
