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. • 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 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 outflow sewage levels and contaminated ground water levels in land fill 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 flood protection and wave profiling, amongst others.

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 indefinite immersion in 700 mH2O, with a selection of cable materials to meet the application....

Excitation voltage PDCR 1800 (mV) Output is ratiometric to supply within 2.5 V to 12 V limits. The minimum supply voltage (VMIN) which must appear across the pressure transmitter terminals is 9 V and is given by the following equation: VMIN = VSUP - (0.02 x RLOOP) Where VSUP is supply voltage in Volts, and RLOOP is total loop resistance in Ohms Recommended power-on time before output sample: Combined effects of non-linearity, hysteresis and repeatability: • Option D: ±0.06% FS BSL maximum (±0.08% FS BSL max. for 1 mH2O and below) (240 mm with Lightning Surge Arrestor) M14 x 1.5 exposed thread...
