ELPRT 100ERH

Product Description

ELPRT-100ERH Analog Electronic Pressure Transmitter is an indigenously developed nuclear-grade pressure transmitter designed for reliable operation under normal, abnormal, and severe accident conditions in nuclear power plants. It is qualified to IEEE-323 and IEEE-344 standards and operates using a capacitance-type sensor for pressure, differential pressure, and absolute pressure measurement. The transmitter features a two-wire 4–20 mA DC output, high accuracy, and a service life of 20 years. It is gamma radiation qualified up to 4.1 MRad TID, LOCA qualified, and seismically tested from 1–100 Hz on all three axes. With adjustable zero, span, and damping, SS-316 construction, and IP-68 ingress protection, it ensures dependable performance in harsh nuclear environments. The ELPRT-100ERH is ideal for critical nuclear process monitoring applications requiring long-term stability and safety compliance.
