PS Pressure Sensors

Zoom

Compact size (PS type)

Precision semiconductor pressure sensor that contributes to downsizing of the apparatus.

Pressure type
･Standard type(with glass base) : Rated pressure 4.9 kPa to 980.7 kPa
･Economy type(without glass base) : Rated pressure 40 kPa

RoHS compliant

Ultra-miniature size: much more compact than the PF pressure sensors offered in the past
- Base area:7.2(W)×7.2(D) mm .283(W) × .283(D) inch
- Only 60% in mounting area and 91% in overall height of previous models (PF)
High-level precision and linearity

A high degree of precision and linear detector response have been achieved by applying the semiconductor strain gauge system. Highly reproducible based on repeated pressure.
Impressive line-up of models
- Taking their place alongside the standard 5kW bridge resistance models are those with a 3.3kW resistance which is optimally suited to 5V drive circuits.
- Economy model (no glass base) gives outstanding value for customer appliances 40kPa(0.4kgf/cm²) and 49kPa(0.5kgf/cm²) units are also available.
Improved ease of DIP pin insertion into printed circuit boards
- The ends of the DIP pins are chamfered to ensure easy insertion into printed circuit boards.
Example of pressure characteristics
(when the rated pressure is between
98.1 kPa{1.0kgf/cm²})

Drive current: 1.5 mA rated current; ambient temperature: 25°C 77°F

Industrial use: pressure switches and pneumatic components, compressed air pressure measuring devices and airbeds
Medical use: blood pressure meters, oxygen generator and airbeds
Others: pressure sensing devices for air pressure mediums
