Cảm biến áp suất Valcom High Accurate Pressure Transmitter for Middle High Pressure VPRT(F) series VPRT-A3-6KS-4

Cảm biến áp suất Valcom High Accurate Pressure Transmitter for Middle High Pressure VPRT(F) series

High accuracy (Nonlinearity: ±0.2%R.C.)

Sensor machined integral with diaphragm offers durability and long life.

Pressure port diameter is as large as 9.5 mm, which allows less sludge or fluid to accumulate

Measured medium Water, oil, gases or other media that will not corrode 15-5PH (precipitation-hardened stainless steel).

Pressure Type Positive and compound pressures can be measured.

Measured Range Can be specified within the range of 1 kPa to 100 MPa of rated capacity (Calibration range: 0.5 MPa to 100 MPa).

Specify more than 50% of rated capacity as the calibration range.

Output type 4–20mA (2 wire system, 4 wire system),

Specify among 4 to 20 mA (2-wire, 4-wire), 1 to 5 V, 0 to 5 V, and 0 to 10 V.
