Type 220DD 

Baratron® General Purpose Differential Capacitance Manometer 

The MKS Type 220DD Baratron® General Purpose Differential Manometer 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.

Features & Benefits 

• All-metal sensor eliminates handling problems associated with glass, mercury, and liquid gauges 

• Useable resolution of 1 part in 10,000 — minimizes the number of capacitance manometers required to cover a wide range of pressures 

• NEMA 1 enclosure provides sensor protection in harsh operating environments 

• Sensor is temperature controlled at 45°C for stable performance 

• Simultaneous 0 to 10 VDC and 4 to 20mA outputs interface with common process control systems
