The NP400 Digital Pressure Gauge and Transmitter is a solution bundle that includes the low-cost NP400 Pressure Transducer and the LoopView LED loop-powered indicator which provides a local display for the NP400.  The bundle can be ordered under one convenient part number with versions available for different pressure ranges.

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.

The LoopView has a 4-digit LED display and 2 keys which allow for quick and easy adjustment of indication range, decimal point position, digital signal filter and user calibration. It's a two-wire 4-20 mA loop-powered indicator that mounts directly on the NP400 and is powered by the current loop so it requires no additional power.
