Panasonic pressure sensors
Panasonic Automotive & Industrial Systems has a range of semiconductor pressure sensors that integrate amplifiers and temperature compensation circuitry (PS-A units).
Precision sensors without amplifier and open wheatstone measurement bridge are also available and in ultra-miniaturised sizes.
There are also versions with chamfered pins for improved ease of DIP pin insertion into PCBs.
The PS-A units come in three types. The standard type with a glass base can handle pressures from ±100kPa to -1000kPa with a total accuracy of ±1.25%.
The economy type without a glass base is for 40kPa pressures and ±4% accuracy and the low-pressure version is for 6kPa and ±2.5% accuracy. Footprint is 7.0 by 7.2mm (10.4 by 10.4mm for the low-pressure type).
The PS and PF sensors come in two versions. The standard type with a glass base is for pressures from 4.9 to 980.7kPa and the economy type without a glass base for 40kPa.
The PS models, which have a footprint of 7.2 x 7.2mm, have a 3.3kΩ resistance.
Applications for the PS units include industrial pressure switches and pneumatic devices and medical blood pressure measurement.
