KPSI 351-Digital Water Level Sensor

Brand: American Sensor Technologies Inc
Request Information Favorite
The KPSI 351 submersible hydrostatic level transducer is specifically designed for small bore applications and to meet the rigorous environments encountered in ground water level measurements. 

Designed and tuned to meet stringent USGS OSW specifications of ±0.01 feet H2O often required by governmental regulatory agencies and research institutions. The KPSI 351 incorporates a highly stable media isolated sensor, and features SDI-12 serial-digital interface. 

SDI-12 is a standard for interfacing data recorders with microprocessor-based sensors, especially in the environmental monitoring field. The KPSI 351 is an excellent solution for applications that require minimal current drain. 

It will accommodate cable lengths between sensors and recorder up to 1,000 feet. The removable cable option allows easy substitution of transducers and cables. A New removable nose cap option extends product applications.
