Measurement & Control

1800 Series

Druck High Performance
Level Pressure Sensors

The PDCR 1800 transducer (mV output) and the
PTX 1800 transmitter (4 to 20 mA output) are the
latest generation of fully submersible titanium
high performance sensors for measurement of
hydrostatic liquid levels.

Features

• Ranges from 0.75 mH2O to 600 mH2O

• Accuracy ±0.10% full scale (FS) best straight
line (BSL)

• Fully welded 17.5 mm diameter titanium
construction

• Polyurethane and hydrocarbon resistant cables

• Full range of installation accessories

Applications

The 1800 Series incorporates many enhanced features
gained from experience in supplying thousands of
sensors for small and large scale installations
worldwide. Example applications include:

• Potable water
From ground water borehole to surface water level
measurements in rivers, canals and reservoirs.

• Waste water and remediation
Monitoring of secondary and outfl ow sewage levels
and contaminated ground water levels in land fi ll sites.

• Tank Level
From land based liquid storage vessels to on-board ship
ballast tank monitoring.

• Sea Water
Marine environmental applications, including tide
gauging, coastal fl ood protection and wave profi ling,
amongst others.

Reliability and Data Quality

The combination of a high technology sensor, together
with advanced signal conditioning and packaging
techniques, provides an ideal long term solution for
reliable, accurate and economical level measurements.
The micromachined silicon element is sealed
within an all-titanium pressure module assembly, fully
isolated from the pressure media. This is contained in a
slimline, welded titanium body, terminated in an
injection moulded cable assembly. The cable features a
Kevlar® strain cord and is IP68 rated for indefi nite
immersion in 700 mH
materials to meet the application.

Ease of Use

A simple datum marked cable system is provided for
ease of installation. 1 m datum points are clearly
marked for quick and accurate cable alignment
below ground level. In addition, a full range of related
accessories simplifi es installation, operation and
maintenance, including:

• Quick-release cable clamp assembly

• Slimline and short profi le sink weights

• Moistureproof Sensor Termination Enclosure

• In-situ pressure test/calibration adaptors

Other units may be specifi ed, such as ftH2O, inH2O, bar,
mbar, kPa, kg/cm2, psi

Overpressure

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

• 8 x for ranges up to 1.5 mH2O

• 6 x for ranges above 1.5 to 3.5 mH2O

• 4 x for ranges above 3.5 mH2O (1400 mH2O max.)

Pressure Containment

• 10 x for ranges up to 3.5 mH2O gauge

• 6 x for ranges above 3.5 mH2O gauge
(1400 mH2O maximum)

• 200 bar for absolute ranges

Media Compatibility

Fluids compatible with titanium (body), acetyl
(nose cone) and polyurethane or Hytrel® 6108 (cable
assembly)
