The NP640 Digital Pressure Gauge and Transmitter is a solution bundle that includes the low-cost and highly accurate NP640 Pressure Transducer and the LoopView LED loop-powered indicator which provides a local display for the NP640. The bundle can be ordered under one convenient part number with versions available for different pressure ranges.
The NP640 pressure transmitter is ideally suited for pressure measurement applications requiring a compact, rugged pressure transducer. It's 0.25% accuracy makes it well-suited for laboratory and R&D applications where precision pressure measurement is required. The rugged stainless steel body also makes them a great choice for industrial environments.
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.
