Hygienic measurement instrumentation are designed for use by the food, drink and pharmaceutical industries, which require a high level of cleanliness in their manufacturing processes.
Diaphragms
Silicon Pressure Sensors
Silicon Pressure Sensors have silicon diaphragms which have a very high elasticity and semiconductor strain gauges which produce a high span sensitivity.
Wet/Dry
Wet/Dry describes a dp measurement device for use with a liquid on the positive pressure side and a dry/non-condensing gas on the negative pressure side.
SOI – Silicon on Insulator
Silicon on Insulator (SOI) is a type of material technology which can be utilised in the manufacture of pressure sensor diaphragms to allow operation at higher temperatures.
Mechanical Stop
Mechanical Stop is an internal component which protects pressure sensing components from overpressure by limiting the deflection of the diaphragm.
Flush Diaphragm
A guide to flush diaphragm pressure & level measurement instrumentation, including explanations, applications and a choice of products with flush process fittings.
Symptons and Causes of Damage to Pressure Transducer Diaphragms
It is possible to view part of the diaphragm on most pressure transducers and some which are completely exposed such as flush diaphragms are particular vulnerable to mechanical damage.
