The PC-29A and PC-29B are low voltage pressure transmitters designed for the measurement of pressure, underpressure, and absolute pressure of gases, vapours, and liquids. These transmitters feature a piezoresistant silicon sensor separated from the medium by a diaphragm and a specially selected manometric liquid. The electronics are housed in a casing with protection ratings from IP65 to IP68, depending on the electrical connection type. They are suitable for use in hazardous environments with an ATEX intrinsic safety version available. The transmitters offer a wide measuring range from 0...25 mbar up to 0...1000 bar, with high accuracy and long-term stability. They support various electrical connections (PD, PZ, PKD, PK, SG, SGM) and process connections (G1/2, M, 1/2NPT, GP, P, G1/4), with options for different materials and protection ratings. The transmitters are designed for easy installation and can be used in a wide range of temperatures, from -40°C to 80°C, with special considerations for high-temperature applications.

Use Cases

  • Measurement of pressure, underpressure, and absolute pressure of gases, vapours, and liquids
  • Measurement of levels and pressures in food and chemical industries with diaphragm seal
  • Use in zones under explosion hazard with ATEX Intrinsic safety version

Capabilities
