WL3100/WL3100A Dry Pressure Transducer
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 aluminum enclosure.
The WL3100 transducer is available as ‘stand alone’ for connection to HS23 dry bubble units (see flipside) or can be fitted 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 an additional location correction factor to better account for atmospheric pressure influence, especially in particularly elevated or deep sites.
