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.
