The intrinsically safe temperature pressure calibrator provides unmatched pressure measurement flexibility compared to any competitive unit.

This temperature pressure calibrator typically provides 0.025% of full scale accuracy on internal pressure sensors. A Pt100 RTD input is provided for temperature measurements accurate to 0.1°C (0.2°F). In addition, the calibrator measures a 4-20 mA loop current. The temperature pressure calibrator supports up to three simultaneous measurements in any combination.

With simultaneous display of as many as two pressures and an RTD temperature measurement, the temperature pressure calibrator is ideal for gas flow or custody transfer calibrations.

The temperature pressure calibrator is available customized with any two ranges selected from 0.4, 1, 5, 7, 15, 30, 100, 300, 500, 1000, 1500, 3000, 5000, or 10,000 psi or absolute pressure ranges of 15, 30, 100, 300 PSIA. It is also available in a calibrator Kit, which includes the Calibrator, Pt100 RTD Probe, batteries, manual, NIST-traceable certificate, test leads, and hard-sided carrying case. The single sensor BetaGauge 311A-EX is also available configured for differential pressure measurement in 0.4, 1, 5, 7, 30 and 100 psi ranges.
