Pressure Sensors

Product Details:

The PDCR 1830 transducer (mV output) and PTX 1830 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 PDCR/PTX 1830 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.

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 indefinite immersion in 700 mH2O, with a selection of cable 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
simplifies installation, operation and maintenance.

• Quick-release cable clamp assembly
• Slimline and short profile sink weights
• Moistureproof Sensor Termination Enclosure
• In-situ pressure test/calibration adaptors

Operating Pressure Ranges:

• PDCR 1830/1840 (mV): 0.75, 1.5 mH2O gauge, 3.5, 7, 10, 15,  20, 35, 50, 70, 100, 150, 200, 350, 600 mH2O gauge and absolute
• PTX 1830/1840 (mA): Any zero based FS from 0.75 to 600 mH2O gauge and 3.5 to 600 mH2O absolute.
  Elevated zero, compound and reversed output ranges
  available. Refer to GE for further information. Other units may be specified, e.g. , ftH2O, inH2O, bar, mbar, kPa, kg/cm2
• 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 maximum)
• 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)
• Excitation Voltage PDCR 1830 (mV): 10 V at 5 mA nominal
  Output is ratiometric to supply within 2.5 V to 12 V
  limits.
• PTX 1830 (mA): 9 to 30 V 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, RLOOP is total loop

Product Details:

RPS/DPS 8000 High Accuracy Resonant Pressure Sensor, For over 40 years, Druck has manufactured precision pressure sensors with a capability to meet critical applications in industrial, aerospace, oil and gas, and research environments. Today, Druck is part of GE Measurement & Control and
has continually worked to develop and improve on the performance of our pressure sensors to meet customer’s requirements. The RPS/DPS 8000 is the first product to incorporate the exciting new TERPS technology. TERPS is
a resonant silicon pressure sensor technology platform that provides an order of magnitude greater accuracy and stability than current pressure measurement technologies available. The new TERPS technology also extends the pressure range
capability to high pressures and by incorporating true pressure media isolation greatly improves its suitability for use in harsh environments. In addition to providing the performance and packaging improvements available with TERPS, the RPS/DPS 8000 product line takes advantage
of best practices to offer a wide range of pressure and electrical connections to enable a level of customization for your specific requirements never before available in the performance class of this sensor. The combination of the power of the TERPS technology and the quality, reliability and flexibility of the RPS/DPS 8000 Series offer a truly unique
solution for high accuracy and high stability pressure measurement requirements.
Features:

• High Precision, ±0.01% FS over compensated temperature range
• High Stability, ±100 ppm FS/year
• Wide temperature range, -40°C to +85°C (-40° to
• 185°F)
• Media isolated construction, suitable for use in harsh environments
• Multiple Output configurations, RS-232, RS-485,
• Frequency & Diode (TTL)
• Wide selection of pressure & electrical connections to suit specific requirements

Base Pressure Ranges:

• 0 t 2 bar (0 to 30 psi) absolute
• 0 to 7 bar (0 to 100 psi) absolute
• 0 to 14 bar (0 to 200 psi) absolute
