The 220DD-00010A2B Baratron® Heated Differential Capacitance Manometer features 1 Torr (1 mm Hg) full scale pressure measurement and a 0.5 inch OD tube fitting. It offers a reliable, accurate, inexpensive solution to measuring low differential pressures. Operating on the variable capacitance technique, the 220DD all-metal sensor contains a tensioned metal diaphragm, one side of which is exposed to the gas whose pressure is to be measured (Px side). The other side (reference, or Pr, side) is adjacent to an electrode assembly which is terminated in another like port. The diaphragm deflects with changing differential pressure, causing a capacitance change between the diaphragm and the adjacent electrode assembly. The capacitance change generates an AC voltage which is amplified, demodulated, and converted into a high level DC voltage output, linear with pressure, and calibrated against a pressure standard. The Type 220DD sensor is temperature controlled at 45°C for enhanced zero and span stability. All components are housed in a rugged, NEMA 1 enclosure for protection when used in harsh environments. Two outputs, 0-10 VDC and 4-20 mA, are provided for interfacing with common process controllers.
