Wet Diff Press Transducer

APPLICATIONS

The Carrier WPR2 Series Remote Wet to Wet Differential Pressure Transmitter is designed to reduce installation time and provide mounting flexibility, often eliminating the need for additional plumbing. They accurately measure wet media pressures in a variety of applications. Commonly used for monitoring pumps, these devices are also ideal for measuring pressure across filters, heat exchangers and compressors. The dual remote sensors are based on a ceramic capacitive sensing element with ¼”-18 NPT male (304 stainless steel) fittings. The WPR2’s enclosure opens conveniently to allow it to be reconfigured between three additional ranges (see Specifications) and outputs of 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC (default). The different configurations in this series can measure both uni or bi-directional pressure ranges as low as 3 psi and as high as 300 psi, depending on the unit. The WPR2 also features a push button auto zero function for remote calibration. The LCD option will display pressure values for both the High and Low side pressures, a differential pressure value, “OVR” for values over the specified range, “ERROR” for differential pressures out of range, and “ZERO” when the auto-zero is in process.
