Setra Systems Inc., a leading global designer and manufacturer of pressure measurement instrumentation for industrial, test and measurement, HVAC/R, semiconductor, energy, environmental, medical, pharmaceutical, and meteorological requirements, has announced its split core magnetic current sensing technology, found within its Current Transducer (CTC) Series.

This Setra Systems sensing technology provides cost-effective high-accuracy measurement of electrical current up to 150 Amps. Such current typically may be found running through the cables and wires used within HVAC/R and industrial applications, including refrigeration units, air handlers, compressors, pumps, fans, small industrial motors and lighting. Offered in three unique models, the CTC Series features a three-position slide switch for user selection of the best amperage range for individual applications. Available versions include industry standard 4-20 mA and 0-5 V outputs, both with 30/60/120 Amp selectable range; and a 0-10 V output version with 20/100/150 Amp selectable range. They are also available in both 24 V DC loop- and self-powered versions. Total measurement accuracy is ?2% of selected range, with an isolation rating of up to 600 V AC RMS.

The series clamped split core and self-gripping iris fingers design allows for the magnetic current transducer to grip onto the cable without additional support. This makes it easy to clamp onto existing power cables or wires within both new and retrofitted installations. In addition, the series is directly compatible with a snap-on command relay. Two optional power relay modules with LED indicators, sold separately as Models CCR-24 (24 V AC/V DC) and CCR-12 (12 V AC/V DC) are available for remote motor startups. Designed for onsite mechanical attachment to the CTC Series, Model CCR relays provide a cost-effective solution for load switching without the need to mount an external relay elsewhere in the control enclosure.

The CTC Series and its split core magnetic current sensing technology are developed and manufactured in-house at Setra Systems own ISO9001 certified facility in Boxborough, Massachusetts, USA, where vertically integrated manufacturing allows for full product quality control, from component through to finished product. Units are also CE marked, UL listed and RoHS compliant. CTC Series units are also available with same or next day shipping.
