Description
The P20T High-Temperature Transmitter is engineered for applications involving media temperatures up to 200°C. It utilizes a piezo-resistive design, where pressure on the diaphragm is transmitted to an imported silicon or sapphire sensing die through a radiating fin. This innovative fin efficiently reduces high media temperatures, eliminating the need for additional cooling systems, while optimizing the performance benefits of piezo-resistive pressure sensors.
The fully welded construction of the P20T, combined with an IP65 protection rating and superior anti-corrosive capabilities, ensures long-term reliability even in demanding high-temperature media pressure measurements. With its robust design and resistance to harsh environments, this transmitter is the perfect solution for applications that require precise pressure measurement in extreme conditions, without the need for supplementary cooling mechanisms.
