The HT24 is a flush diaphragm pressure sensor built around a highly stable diffused silicon chip. Pressure is transmitted to the sensitive chip through a stainless steel diaphragm and sealed silicon oil, so the chip never comes into direct contact with the measured medium. Its flat diaphragm structure makes the sensor easy to clean and highly reliable, making it well suited to food, hygiene, and other demanding industrial applications.
