KPSI 351 Series Pressure Transducer

Description: The MEAS KPSI 351 submersible hydrostatic level transducer is specifically designed for small bore high accuracy applications and to meet the rigorous environments encountered in ground water level measurements. Incorporating a highly stable media-isolated sensor, the MEAS KPSI 351 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 MEAS KPSI 351 is intended for applications with requirements that include battery-powered operation with minimal current drain, low system cost, and use of a single recorder with multiple sensors “daisy-chained” on one cable. It will accommodate cable lengths between sensors and recorder up to 200 feet. Our new removable cable option allows easy substitution of transducers and cables.
