Basic Information

High precision pressure sensor (without amp.)

PS Pressure Sensors image

RoHS compliant

Features

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.
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

Please consult us if a pressure medium other than air is to be used.
This is the regulation which applies within the compensation temperature range.
Please consult us if the intended use involves a negative pressure.
