The Series WPR2 Wet/Wet Differential Pressure Transmitter monitors differential pressure of air and compatible gases and liquids with 1.0% accuracy. The design employs dual pressure sensors converting pressure changes into a standard 4 to 20 mA output signal or field selectable voltage. Small internal volume and minimal moving parts result in exceptional response and reliability. The WPR2 family has a robust NEMA 4X (IP66) construction, which is also available with an integral LCD for localized data monitoring and with a remote sensor option.
