The PX2670 series has been discontinued. Please see the PX655 as possible alternatives or contact our Pressure Engineering department.
OMEGA PX2670 Series pressure transducers sense either differential or gage pressure and convert this pressure to a highly accurate electrical signal. Used in building energy management systems, these transducers are capable of measuring pressures and flows with a high degree of accuracy to improve overall system efficiency. The units are temperature compensated to better than 0.33% FS/‹F over the range of 40 to 150‹F and have an IP65/NEMA-4 rated package to withstand environmental effects. A 31.2-digit LCD display is optional.
