BetaGauge 321 Dual Sensor Pressure Calibrator |
|
BetaGauge 321
Pressure calibrator.
BetaGauge 321 Pressure calibrator
provides 0.025% FS accuracy on 2 internal, isolated, stainless steel
pressure sensors, while external connection supports all BetaPort-P
pressure modules.
Accurate to 0.2°F, Pt100 RTD input is provided for temperature
measurements, and product also measures 4-20 mA loop current and up to
30 Vdc. Unit supports up to 3 simultaneous measurements in any
combination. It is available in 15 psi/1,500 psi or 30 psi/3,000 psi
ranges or customized with
any two ranges selected from 5, 15, 100, 300, 500, 1000, 3000, 5000, or
10,000 psi..
