Digital Pressure Calibrator

数字压力校准仪

Instrument technicians calibrating transmitters, gauges and switches on site carry this documenting calibrator. Modules span −100 kPa to 70 MPa with ±0.025–0.05 % FS accuracy, and the unit measures 0–24 mA and 0–30 V while supplying 24 V DC loop power. Specify 1/4 in NPT or G1/4 connections and the pressure modules you need.

Pressure range: −100 kPa to 70 MPa (by module)
Accuracy: ±0.025–0.05 % FS
Resolution: 5 digits
Electrical measurement: 0–24 mA, 0–30 V
Loop power supply: 24 V DC
