  • Low Cost
  • Compact Size
  • 0.50% Accuracy (model dependent)
  • 316 Stainless Steel Body
  • 1/4 Inch NPT Process Fitting
  • Two Wire 4-20 mA Output

The NP400 pressure transmitter is ideally suited for pressure measurement applications requiring a compact, rugged pressure transducer. It's low cost makes it ideal for price sensitive and OEM applications. The NP400 is machined from 316 stainless steel and features a a piezoresistive ceramic sensor.  The output of the NP400 is a thermally compensated two wire 4-20 mA  signal proportional to the input range.


Add an Optional Local Display with LoopView

LoopView is a two-wire 4-20 mA loop-powered indicator which mounts directly on transducers providing a local display.
