The NP620 is being replaced by the NP640 which is a newer design featuring all stainless steel wetted parts.


The NP620 family of industrial pressure transmitters 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 NP620 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.
