Stevens SDX Pressure Sensor

T-SDX-93720-xxx-xxx

The Stevens SDX (Submersible Depth Transmitter) is a high-accuracy water level/depth sensor that works with Onset’s HOBO® RX3000 cellular weather station to bring your water level data to the web. Suitable for a wide range of level monitoring applications, the SDX is a cost-effective option for remote, real-time water level data collection. It is recommended that each SDX vent tube is protected from water ingress with either a vent tube cap (T-SDX-93030-500) or a desiccant cartidge (T-SDX-93030-010).
