TruBlue 555 checks water quality
01 September 2011
TRESSURE Systems, a US-based manufacturer of precision level and pressure instrumentation for environmental water usage and water resource applications, has introduced TruBlue, a new line of submersible level transducers that measure water level and water quality.
The TruBlue 555 Level is part of the new TruBlue line specifically designed for long-term measurement of water levels in environmental and watershed management applications including ground water, surface water, canal and harbour monitoring.
Featuring an advanced, power-conserving microprocessor technology, the transducer also offers more memory and a longer battery lifespan.
“With an internal memory of 8 MB, TruBlue 555 is capable of storing up to 550,000 level and temperature measurements,” says a spokesman for the company. “Its internal 3.6 V lithium battery with on-board surge protection has a lifespan of five years based on four readings per hour, making the transducer ideal for remote environmental data collection and process monitoring. In addition, the new unit provides an accuracy of +0.1 per cent FS total error band, which includes changes in temperature within the compensated temperature range. The transducer has an RS-485 electrical interface.”
The TruBlue 555 Level transducer is shipped with TruWare, Pressure Systems’ user-friendly software created specifically for the TruBlue line. Users are able to graph and export data using this new software and easily manage their data. The software is available for both PC and mobile applications.
The transducer sampling modes include linear, linear averaging and event, with programmable sampling rates of up to five readings per second. It is available in full-scale water level ranges from 0 to 11.5 ft to 0 to 658 ft (from 5 to 300 psi). The ¾-inch diameter unit comes in welded 316 stainless steel or titanium, making it suitable for a variety of applications including brackish and seawater. The operating temperature range is 0 to 50 deg C. The TruBlue 555 has a two-year warranty and comes standard with a calibration report.
