The NP640 is a family of industrial pressure transmitters with all wetted steel parts.  They are robust and reliable transducers suitable for general industrial applications. They feature piezoresistive oil-filled pressure front-end technology, digital field calibration capabilities and a wide range of pressure measurement ranges.

With a 0.25% accuracy the transducers are well suited for laboratory and R&D applications where precision pressure measurement is required. The rugged stainless steel body also makes them a good choice for industrial environments.

The NP640 transmitters 4-20mA output range is configurable to zoom up to 1/3 of the nominal range. This is accomplished using a USB connection to a Windows computer with the optional TxConfig-DIN43650 interface cable and free downloadable TxConfigII software. The factory calibration may also be adjusted in the field using the same software and cable connection.

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.
