NCS-PT105IISD Vertical Diffused Silicon DP Pressure Transmitter

NCS-PT105IISD

Product Overview

The NCS-PT105IISD Intelligent Pressure Transmitter features an advanced, proven, and highly reliable pressure sensor, meticulously engineered through integration of cutting-edge microprocessor technology and digital signal processing.

Leveraging the robust processing power and high-speed computation of its embedded microprocessor, the transmitter delivers superior performance characteristics, including intelligent functionality, exceptional accuracy, outstanding reliability, and excellent long-term zero stability.

The integrated LCD display module provides real-time visualization of key process variables, such as pressure, temperature, and output current. Intuitive local keypad operation enables convenient on-site configuration, including zero-point adjustment (migration), span/range setting, and additional parameters, facilitating efficient field commissioning and maintenance.

Supporting the PROFIBUS DP communication protocol, the transmitter accurately measures a wide range of industrial process variables, including pressure, differential pressure, liquid level, and flow. It is ideally suited for demanding applications across industries such as petroleum, chemical processing, power generation, and metallurgy.
