Description
The PR3202LR ultra-low range sensor accurately measures differential pressure from as little as 0-0.25mbar to an accuracy of better than ±1% of full scale. Thanks to the PR3202LRs stainless steel capacitive sensing element, the sensor requires minimal amplification which provides excellent accuracy and long-term stability.
It is enclosed in an IP65 / NEMA 4 plastic glass-filled polycarbonate UL94v-0 case enabling it to withstand many harsh environments. Zero and span adjustments are accessible inside the case allowing for easy on-site adjustment if required.
The PR3202LR ultra low range differential pressure sensor is designed for tiny pressure measurements of dry, non-corrosive gases in applications such as HVAC systems, clean room monitoring and over pressurisation, static duct pressure and energy management systems.
This ultra-low range differential pressure sensor comes with 3/16″ OD barbed brass pressure connections to suit flexible hose, while electrical connection is made via a cable gland to internal screw terminals.
