Product Description

ELPRT-100SPT Smart Pressure Transmitter is a high-performance 2-wire pressure measurement solution for accurate monitoring of liquids, gases, vapors, and steam. It uses piezo-resistive and capacitive sensor technology to deliver excellent long-term stability and fast response. The transmitter provides a 4–20 mA output with superimposed HART communication, enabling advanced diagnostics and configuration. With a wide turndown ratio up to 100:1, built-in LCD display, and robust IP66 enclosure, it is suitable for demanding industrial environments. ATEX certification, high overpressure protection, and multiple process connection options, including remote seals, ensure safe and flexible installation. The ELPRT-100SPT is ideal for critical pressure and level measurement applications across process industries.
