Pressure Systems Adds Absolute Reference Pressure Format with Atmospheric Pressure Compensation to Datalogging Kpsi(TM) Transducers


Hampton, VA, February 2006 -- Pressure Systems, manufacturer of KPSI(TM) Level and Pressure Transducers, now offers its waterMONITOR submersible datalogging level transducer in an absolute reference pressure format. The sealed reference design simplifies maintenance, since no vent tube or associated desiccant filter is required to guard against moisture incursion. In addition, a specialized configuration of this transducer, the baroMONITOR, has been developed to collect corresponding barometric (atmospheric) pressure readings. These measurements are used to compensate for errors in the absolute level measurements induced by changing barometric pressure.

The error compensation for the barometric pressure is executed under the control of
K-ware, Pressure Systems' intuitive yet comprehensive Visual Basic-based applications software. K-ware easily guides users through the process of extracting measurements from the transducers and presenting the data in a variety of formats for analysis as well as for export to another software program. The software package comes standard with both the waterMONITOR and baroMONITOR. Upgrades are available on Pressure
Systems' web site at no charge: http://pressuresystems.com/KPSI_software.html.

The waterMONITOR and baroMONITOR are ideal for a wide range of groundwater and surface water applications in areas such as boreholes, tanks, rivers, lakes, and streams. The new transducers can each store up to 600,000 level, temperature, and time stamp measurements. The units have full-scale level ranges from 10 ft. to 692 ft. (3 m to
210 m) H2O with an accuracy of up to +/-0.05% FS TEB (Total Error Band) over the compensated temperature range of 14°F to 104°F (-10°C to 40°C). The baroMONITOR has a pressure range of 8 to 16 psia (55 to 110 kPa). The transducer electronics, along with two replaceable AA batteries, are completely sealed in a 3/4" stainless steel or titanium housing.

The transducers' selectable sampling modes include linear, linear averaging, event, and logarithmic. The units also feature programmable sampling rates of up to 15 readings/second; incorporate internal non-volatile memory of 2 MB or 4 MB; and upload data at 100 scans/second at a baud rate of 19,200, with a pressure and temperature time stamp.

Pricing for the waterMONITOR and the baroMONITOR starts at $695 per unit. Delivery is 20 days ARO.
