Duct Static Pressure Transmitter PR276 Series

Duct Static Pressure Transmitter


The MAMAC Systems Model PR276 Duct Static Pressure Transmitter incorporates sophisticated integrated circuits and a new micro-machined glass-on-silicon (Gl-Si) capacitance sensor to not only provide a high level, fully conditioned and temperature compensated output, but also to offer up to three (3) field selectable pressure ranges in one unit. The field selectable feature eliminates costly inefficiencies by providing a single unit which can be configured to cover all the pressure ranges for a particular application. For instance, 1.25″, 2.50″ and 5.00″ W.C. are in one unit. To substantially reduce installation cost and to eliminate costly control panels, the Model PR276 incorporates a pressure sensor and a static pressure tip integrated as one assembly. Two industry standard output versions are available, 4-20mA 2-wire loop or field selectable 0-5 VDC/0-10 VDC. Wide 12-40 VDC or 12-35 VAC unregulated supply voltage and a broad 25°F−150°F compensated temperature range ensures compatibility to most of the applications. Rugged NEMA 4 (lP-65) enclosure, gasketed cover, external mounting bracket, fully temperature compensated NIST traceable accuracy, and a liberal five year warranty are some of the features which make the Model PR276 not only the most reliable, but the lowest installed cost duct pressure sensor in the industry.
