Pressure test tools

Davidson Measurement has released the DPI 800 series of calibrators. Nine models cover pressure and temperature, dual function versions also provide additional facilities for measuring mA, supplying 24 V power, testing switches and providing Hart compatibility.

Pressure models DPI800/802 use intelligent digital output sensors to provide 0.05% FS accuracy from 0 to 50°C, including one year stability (0.01% FS precision optional) and a choice of 22 pressure ranges is available from 25 mbar to 200 bar.

The DPI811/812 temperature variants provide RTD measure/source capability with 2, 3, 4 wire auto detection for identification of sensor and wiring faults.

The DPI820, a dual input data logging thermometer and the DPI 821/822 thermocouple calibrators use cold junction compensation to keep errors within 0.2°C, even for a 30°C rapid change in ambient temperature.

IDOS plug-in modules expand the range of any IDOS-compatible instrument and can convert a temperature calibrator into a fully featured pressure indicator.
