g

• Ranges from 5 to 900 psi

• Accuracy ±0.25% full scale (FS) best straight line (BSL)

• Fully welded 0.69 in 316 stainless steel construction

• Pulse power operation

• Polyurethane cable

• Full range of installation accessories

The PDCR 1730 transducer (mV output) and PTX 1730
transmitter (4 to 20 mA output) are the latest generation
of fully submersible, 316 stainless steel, high performance
sensors for measurement of hydrostatic liquid levels.

Application specific features include a Kevlar

®

strain
relieved vented cable, internal condensation protection
and an IP68 injection moulded cable assembly, which
ensures sensor operation over an extended lifetime.

Features

1730 is a Druck product. Druck has
joined other GE high-technology
sensing businesses under a new
name

—GE Sensing.

Pressure Measurement

Operating Pressure Ranges
PDCR 1730 (mV)/PTX 1730 (mA)

5, 10, 15, 20, 30, 50, 75, 100, 150, 300, 500, 900 psi gauge

Overpressure

The operating FS pressure range can be exceeded by the
following multiples with negligible effect on calibration.

• 4 x for 5 psi range

• 2 x for ranges 10 to 900 psi

Pressure Containment

• 10 x for 5 psi range

• 4 x for ranges up to 900 psi (2000 psi maximum)

Media Compatibility

Fluids compatible with 316 stainless steel, polyurethane
(cable) and EPDM (nose cone).

Excitation Voltage
PDCR 1730 (mV)

10 V at 1 mA nominal
Output is fully ratiometric to supply within 2.5 V to 12 V
limits.

For pulse power operation refer to technical note.

The minimum supply voltage (V

MIN

) which must appear
across the pressure transmitter terminals is 9 V and is
given by the following equation:
