Series 676 duct pressure transmitter offers an accuracy of ±1% of full scale and a temperature range of 0 to 175 degrees F (-18 to 80 degrees C). Each unit features a micromachined glass-on-silicon (Gl-Si) capacitance sensor that provides a high-level, fully conditioned and temperature-compensated 4-20 mA output, the company says. This duct pressure transmitter also has three field-selectable pressure ranges, a NEMA 4 (IP-65) enclosure, gasketed cover, and external mounting bracket.
