- 2. ADVANCED PRESSURE SENSORS FOR A WORLD OF LEVEL MEASUREMENTS Established in 1972, GE Druck specialises in the manufacture of high performance pressure measurement and related control equipment. The PDCR 1830/1840 transducer (mV output) and PTX 1830/1840 transmitter (4-20 mA output) are the latest generation of fully submersible high performance sensors for measurement of hydrostatic liquid levels. The PDCR/PTX 1830/1840 series incorporates many enhanced features gained from Druck’s experience in supplying thousands of sensors for small and large scale installations worldwide. Example applications include: ⅷ Potable Water From ground water borehole to surface water level measurements in rivers, canals and reservoirs. ⅷ Waste Water and Remediation Monitoring of secondary and outflow sewage levels within certified hazardous areas and contaminated ground water levels in land fill sites. ⅷ Tank Level From land based liquid storage vessels to on-board ship ballast tank monitoring within safe and certified hazardous areas, using potable water approved (1830) cable and hydrocarbon resistant (1840) cable. ⅷ Sea Water Marine environmental applications including tide gauging, coastal/flood protection and wave profiling 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 GE Druck 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 selection of cable material to meet the application. Lightning Surge Protection An optional integral lightning surge arrestor is available, qualified to the highest European standard IEC 61000-4-5 (level 4). This protects the sensor from raised earth potentials caused by lightning strikes, which often occur in surface water applications. Ease of Use A simple datum marked cable system is provided for ease of installation. Incremental 1 m datum points are clearly marked for quick and accurate alignment below ground level. In addition, a full range of related accessories simplifies installation, operation and maintenance. ⅷ Quick-release cable clamp assembly ⅷ Slimline and short profile sink weights ⅷ Moistureproof Sensor Termination Enclosure ⅷ In-situ pressure test/calibration adaptors P D C R / P T X 1 8 3 0 / 1 8 4 0 S e r i e s High Performance Level Pressure Sensors
