- Marine Industry: Especially on submarines it is very precise how much oxygen the crew has; pressure sensors regulate the amount.
Distributors in Finland
Because pressure sensors are used in so many things, Finland has an endless amount of vendors from small retailers to large distributors.
Piezoelectric transducers:write here about your topic
We chose as our Piezoelectric sensor an PiezoStar® Pressure Sensor Type 6125C.
Sensors sensitivity:
Sensitivity-33 pC/bar
Acceleration sensitivity:
- axial: <0,003 bar/g
- radial:<0,0005 bar/g
Sensitivity change:
- 250 C +- 100 1 %
- RT...350 C +- 2 %
There are different kind of sensors on the market with different amount of bars. New piezo materials (PiezoStar crystal) inprove the sensors performance.
Other Characteristics:
Operating temperature range -20...350 C
Measurin range 0...300 bar
Natural frequence >70 kHz
