Description
The LL-MINI-GAUGE-050 is a 50m water level sensor with temperature measurements. The sensor incorporates a vented piezoresistive sensor to monitor depth and integral temperature sensor. This sensor does require a vent tube to the surface and does actively compensated for barometric pressure readings. This ensuring accurate readings across the full operational temperature range of -20 to +80°C. Users can select from a range of vented cables and AquaConn connectors.
The sensor housing is constructed from a carbon fibre and titanium composite. This material selection provides a high strength-to-weight ratio and enhanced corrosion resistance, critical for reliable long-term deployment in challenging environmental conditions, including saline solutions.
