Pressure sensors
For almost every purpose
  • low dead volume (≤ 47 μl)
  • self-venting
  • calibrated and temperature compensated
  • effective media resistance
    (parts in contact with medium: Teflon, silicon)
  • pressure range: 0 up to 10bar
    (35 bar maximum pressure without irreversible damages)
  • short-circuit proof output
  • TTL (5V) supply voltage
  • internal voltage reference: 0,5 up to 4,5V output

Supply voltage: 4,8 ...5,3V

 

Environmental conditions:
Storage temperature: -55°C - +100°C
Ambient temperature during operation: -40°C - + 85°C
Relative humidity: 0...95%

Measuring effect:
Piezo resistant is formed by a p-endowed diffused resistance in a n-endowed semiconductor substrate. If this substrate and with it also the Piezo-resistant-mechanical tensions is put out, the electrical resistance changes.
