ELPRT 100SDP

Product Description

ELPRT-100SDP Smart Differential Pressure Transmitter is a microcontroller-based instrument designed for precise differential pressure measurement of liquids, gases, and vapors in industrial applications. It uses a capacitive sensor with diaphragm to deliver high accuracy and excellent long-term stability across a wide measuring range. The transmitter provides a 4–20 mA output with superimposed HART communication, enabling remote configuration and diagnostics. Featuring a two-wire system, rangeability up to 100:1, and a clear LCD display with non-intrusive magnetic controls, it ensures flexible operation. The ATEX-certified, rigid construction with IP66 protection makes it suitable for harsh environments. With options for remote seals and multiple process connections, the ELPRT-100SDP is ideal for pressure, level, flow, and differential pressure applications.
