RTX 1930 Series - Rangeable Submersible Pressure Transmitter

RTX 1930 Series - Rangeable Submersible Pressure Transmitter

 

The RTX 1930 Series, through the use of digital correction techniques and a serial configuration interface, offers a 4-20mA sensor with unparalleled accuracy, flexibility and reliability to the customer.

 

The fully welded construction of the RTX 1930 sensor, which contains no O-rings and incorporates all the enhanced features of a GE Druck family of level sensors developed over 25 years of application use, provides an ideal long-term solution for a reliable, accurate and economical level measurement.

Features

  • Ranges from 0.6 mH2O to 700 mH2O
  • Accuracy 0.06%
  • Fully welded 316 stainless construction
  • 4:1 Downranging
  • 4 to 20 mA output
  • Full range of installation accessories
  • Register for free CD-Rom

Applications

The accuracy and flexibility of the 1930 Series reduces the whole life cost for the user in a variety of level applications:

  • Surface water
  • Tank level
  • Borehole water
  • Waste water and remediation

Specifications

Operating Pressure Ranges Any zero based FS from 0.625 mH2O to 700 mH2O gauge
Standard Pressure Ranges

The standard Upper Range Limit (URL) can be configured by the customer to any intermediate range determined by the Range Adjustment Limits.

mH2O: 2.5, 5, 10, 15, 20, 35, 50, 100, 150, 200, 350, 700

ftH2O: 8, 16, 33, 50, 66, 115, 160, 335, 500, 650, 1150, 2300

Sensors can be provided with a pressure calibration at a down ranged FS, (e.g., 17 mH2O) at an additional cost (refer to Option C). Other units are software selectable e.g. mmH2O, ftH2O,inH2O, mbar, psi, bar.

Range Adjustment Limits

Downranging (4:1)—full 4 to 20 mA output change for any user zero based span setting up to the Upper Range Limit (URL) from 25 to 100% (URL).

Reverse (20 to 4 mA)—output can be inverted to give reducing current with increasing level, e.g. 0 to 10 mH2O (0 to 15 psi) range provides a 20 to 4 mA output as a power saving feature.

Elevation—the 4 mA output can be elevated within 0 to 75% of the Upper Range Limit (URL), e.g. 0 to 10 mH2O (0 to 15 psi) range can be elevated up to 7.5 to 10 mH2O (10 to 15 psi), with corresponding 4 to 20 mA output, e.g for water tower applications.

Overpressure Standard Pressure Ranges (URL) can be exceeded by the following multiples with negligible effect on performance:
  • 6 x for ranges to 2.5 mH2O (4 psi)
  • 4 x for ranges above 2.5 mH2O (4 psi) (1400 mH2O (2000 psi) max)
Pressure Containment
  • 10 x for ranges to 2.5 mH2O (4 psi)
  • 6 x for ranges above 2.5 mH2O (4 psi) (1400 mH2O (2000 psi) max)
Output Signal
  • 4 to 20 mA proportional to the level input in normal operation
  • 3.8 to 20.5 mA proportional to the Loop Cal input in Remote Configuration Software (RCS) operation

Performance Specification

Accuracy The combined effects of Non-Linearity, Hysteresis and Repeatability on standard pressure ranges (URL)
  • Standard: ±0.1% FS BSL maximum
  • Option A: ±0.06% FS BSL maximum
Zero Offset and Span Setting Customer controlled with Remote Configuration Software (RCS).
Long Term Stability 0.1% URL per annum 0.2% for ranges below 5 mH2O (7.5 psi).
