Miniature strain gauge handles tough
environments
The Sensit P150 miniature strain gauge can easily be incorporated into a compact housing, as part of OEM equipment.
Roxspur Measurement and Control has further developed its range of strain gauge - based pressure measurement capsules, and introduced the Sensit P150 miniature sensor, which is only 15mm in diameter Using state of the art thick film strain gauge bridge technology, and the well established Sensit expertise in alumina ceramics, the P150 offers a high output (1-5mV/V), high linearity sensor

Sensor monitors 1-200bar pressures
The Sensit Economic Industrial Transmitter incorporates an ASIC circuit to ensure accuracy and temperature compensation across all environmental conditions.
Using modern thick film production techniques, the sensor is fired onto a ceramic diaphragm, and the bridge components automatically laser trimmed, achieving a low cost element.
Glass fusion of the resulting diaphragm to a rigid ceramic case results in a self-contained, hermetically sealed pressure capsule.
All external surfaces are ceramic, therefore totally inert, unaffected by any liquids or corrosive fluids, and offer unrivalled abrasion resistance.
Capsules can be offered as either gauge or absolute pressure sensors with operational ranges from 400mbar to 200bar.
Supplied as a flat faced 15mm diameter alumina ceramic capsule, the Sensit P150 is a component that can easily be incorporated into a compact housing, as part of OEM equipment.
The experienced engineers at Roxspur are skilled in providing custom mechanical housings and electronic interfaces, allowing the sensor to incorporate any end user design requirement.
Using this engineering design support also allows designs with ATEX approval, with EA/FDA approved materials, or for high static pressure and temperature use.
This has led to the Sensit capsules being incorporated into hydrographic survey diving vessels and submarine cables, in oilfield well monitoring equipment and reservoir monitoring sensors, as well as built into weather monitoring systems and electronic dataloggers.
The 15mm diameter of the new P150 unit has allowed transducer housing designs with smaller size and weight, for example making a 17.5mm diameter water level sensor possible for use in boreholes.
