Atmospheric pressure transducer WL series

differential4-20 mAcurrent output

WL3100 is a dry/dry differential pressure transducer. The difference between the pressure on the high and low pressure ports is linearized and converted to a usable 4-20 mA current output and made available as a digital serial SDI-12 output. The SDI-12 output transmits up to a distance of 60 m (200 ft). The 4-20 mA and SDI-12 outputs can operate simultaneously allowing redundant connection to up to 2 data loggers or RTUs. WL3100 and WL3100A are mounted in a vented rugged aluminium enclosure. The WL3100 transducer is available as ‘stand alone’ for connection to HS23 dry bubble units (see fl ipside) or can be fi tted as a component of the HS40 Series II or HS40 Compact bubbler system. Two models: WL3100 and WL3100A The two units share the same base technology and have very similar specs. The WL3100A is an advanced model with a wider temperature range starting at -40 °C and additional location correction factor to better account for atmospheric pressure infl uence, especially in particularly elevated or deep sites High accuracy +/-0.02 % full scale Compatible with many pressure measurement applications Available in ranges from 5 m (16 ft) to 50 m (164 ft) SDI-12 and 4-20mA output at the same time Low power consumption Factory calibrated by HyQuest Solutions with certifi cat Range - 0-5 m, 0-10 m, 0-15 m, 0-20 m, 0-40 m, 0-50 m water head Accuracy - +/-0.02 % FS (full temperature compensation) Overpressure - 2.67 x range Longterm Stability - Typically +/-0.05 % FS per annum Power Supply - Operating : 9.6 -16 V DC
