Description
Radial pressure sensors are high-tech equipment designed for continuous conversion of pressure into a proportional electrical signal.
Their design is based on tenzo-modules manufactured using silicon-on-sapphire (SOS) technology, which are distinguished by high reproducibility of characteristics and long-term stability. The SOS structure is the basis for the production of radiation-resistant integrated circuits, which is especially important for the space industry, military applications, and nuclear power. A diaphragm made of titanium alloy ensures excellent corrosion resistance in most measured media.
Radial pressure sensors presented in the AO NPK VIP catalog have the following advantages:
-
Low hysteresis values
-
Wide operating temperature range
-
High output signal level and overload capacity
-
High resistance to ionizing radiation
-
High protection against aggressive media
