The HTS-PM03X series flush-diaphragm pressure transmitter is designed for applications requiring high levels of cleanliness, such as in the food and sanitary industries. It features a diaphragm welded to the very front of the process connection to directly sense pressure signals. Utilizing a diffused silicon chip as the sensing element and integrated with specialized digital circuitry, the device processes signals—including amplification, linearity compensation, anti-interference measures, and surge protection—to output an industrial standard signal.
