Miniature Pressure Transducer with Integrated Temperature Sensor

The HKM/T-519-562 is a miniature threaded pressure transducer. The hexagonal head and o-ring seal make it easy to mount and simple to apply.
The HKM/T-519-562 utilizes a flush metal diaphragm as a force collector. A solid state piezoresistive sensing element is located immediately behind this metal diaphragm which is protected by a metal screen. Force transfer is accomplished via an intervening film of non-compressible silicone oil. The platinum RTD protrudes beside the diaphragm to sense media temperature. The pressure and temperature devices are designed to operate independently. This sensing sub assembly is welded to a stainless steel body.
This advanced construction results in a highly stable, reliable and rugged instrument with all the advantages of microcircuitry: significant miniaturization, excellent repeatability, low power consumption, etc. The miniaturization process also yields a marked increase in the natural frequencies of the transducers, making them suitable for use even in shock pressure measurements.
