W&B Instruments has announced the release of the Delta OHM model HD2047 Pt100 calibrator specifically designed for field use with Pt100 instrumentation.

The calibrator will both simulate the Pt100 signal and provide the loop supply, and also measure the loop current. Power supply is four AA batteries.

The HD2047 can be used as a 2, 3 or 4 wire Pt100 simulator over the range -100/+500°C with 24 fixed steps and an accuracy of ±0.5% of simulated value.

The input measurement operates in three modes: voltage measurement (±20V dc), current measurement (0.00-22.0mA) and current measurement with the loop power supply being generated. Measurement accuracy is ±0.01mA.

The HD2047 is extremely simple to operate and is a fraction of the price of full-featured field calibrators that are often used for Pt100 instrumentation only.

The unit comes complete with carry case, leads and NATA traceable calibration certificate and carries a two year warranty.
