NSL 8257 – Low Pressure Transmitter

The very compact NSL low pressure transmitter is the only pressure transmitter in the market with thin-film-on-steel-membrane and pressure ranges down to 0 .. 200 mbar. This combination allows also for low pressure ranges accurate measurements with excellent longterm stability. Through the extraordinary high burst pressures up to 125 times nominal pressure the NSL is the first choice for critial applications.

Features

  • Smallest design
  • Relative or absolute pressure measurement
  • Excellent temperature resistance
  • Improved vibration resistance
  • Completely welded steel sensor system without additional seals
