Polltech - Model PSI-DPC 1 -Digital Pressure Calibrator
Model PSI-DPC-1 is a compact instrument, which comes in three models namely PSI-DPC-1-HH, PSI-DPC-1-TT and PSI-DPC-1-IB which are distinguished in respect of the cabinet, operating power supply and maximum measurement range and are similar in all other respects. PSI-DPC-1-HH is a battery operated, hand held instrument and is normally used for pressures up to 100 psi full scale with internal sensor.
Range :
- Differential Pressure: 0.3 to 100 psid with internal sensor
- Gauge Pressure: 0.3 to 150 psig with internal sensor
- 15 to 10000 psig with external sensor
- Absolute Pressure: 1150 mbar with internal sensor
- 500 PSIA with external sensor
- Accuracy: ± 0.1% of FS customizable to ± 0.05%
Applications
Calibration of pressure meters and indicators.
PSI-DPC-1-TT is a table top instrument and can be used for any pressure range from 100 mm WC full scale to 10000 psi full scale. PSI-DPC-1-TT is supplied generally as mains operated but can be made battery operated for ranges up to 1000 psi.
PSI-DPC-1-IB is supplied as battery operated with rechargeable Li-ion battery for ranges up to 5000 psi. All the models PSI-DPC-1-HH and PSI-DPC-1-TT and PSI-DPC-1-IB are similar in functionality; they will be simply referred to as DPC-1 henceforth in this text.
DPC-1 comprises a pressure sensor and electronics. All the parts including the pressure sensor and electronics and pressure connections are housed inside or on the single instrument cabinet for most general applications involving non-corrosive fluids like air and moderate pressure range viz. 0-0.3 PSI, 0-0.8 PSI, 0-1 PSI, 0-3 PSI, 0-5 PSI, 0-15 PSI, 0-30 PSI, 0-100 PSI and 0-150 PSI F.S. For applications involving pressures higher than 150 PSI and up to 10000 PSI, sensors with stainless steel isolated diaphragm and SS body are available. These sensors are located outside the instrument cabinet as such or packaged as a probe. These sensors are also available for lower pressures and are suitable for applications involving liquids and corrosive gases
