Hampton, Va. Pressure Systems, Inc. offers two new submersible KPSI hydrostatic level transducers that are designed specifically for compatibility with Campbell Scientific dataloggers. The Model 116 and 126 transducers provide an innovative ratiometric mV analog output to achieve a total error band (TEB) accuracy of ±0.3%, making them suitable for surface and groundwater level measurement and control applications, including well and surface water monitoring, soil remediation, and dewatering.
Available in custom lengths, the new transducer cable incorporates Kevlar strength tensioning members to prevent cable elongation as well as a unique, self-sealing water block feature in case of minor cuts or abrasions. The cable features a total of six wires to enable sensing of the sensor bridge input voltage, which the datalogger uses to compensate for any deviations. This enables the TEB specification to be maintained over the compensated temperature range of 32°F to 86°F (0°C to 30°C), said the company. Static accuracy, independent of temperature effects, is ±0.10% FSO for the Model 126 and ±0.25% FSO for the Model 116.
Constructed of 316 SS or titanium, the new transducers are available in full-scale level ranges from 10 to 230 ft H20 (3 to 70 m H20) with custom ranges available, proof pressure of 1.5x FS, and burst pressure of 2.0x FS. The units can operate over the temperature range of -4°F to 140°F (-20°C to 60°C). The transducers are CE-compliant to EN 61000-6-4:2001 as well as EN 61000-6-2:2001 and are shipped with a vent filter that prevents moisture from entering the vent tube.
Transducer pricing starts at $645. Delivery is ten working days.
