The temperature pressure calibrator provides unmatched pressure measurement flexibility over any competitive unit, setting a new standard over the venerable BetaGauge 320.

This temperature pressure calibrator provides 0.025% FS accuracy on both internal, isolated and stainless steel pressure sensors. An external pressure module connection supports all BetaPort-P pressure modules for greater measurement capability. A Pt100 RTD input is provided for temperature measurements accurate to 0.1 C (0.2 F). In addition, the temperature calibration device measures a 4-20 mA loop current and up to 30 VDC. An internal 24 Volt Loop Power Supply can power a transmitter. The temperature pressure calibrator supports up to three simultaneous measurements in any combination, including three pressure measurements.

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

The temperature pressure calibrator is available in two standard configurations: 15 psi/1500 psi or 30 psi/3000 psi ranges, or customized with any two ranges selected from 5, 15, 30, 100, 300, 500, 1000, 1500, 3000, 5000, or 10,000 psi. 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. Also available with single pressure sensor as the BetaGauge 311.
