Diaphragm Seals Accessories

Plain and Armored Capillaries

  • Stainless steel capillaries available with or without stainless steel armor
  • Protects the instrument from high or low process temperatures
  • Allows remote mounting of pressure instrument(s)
  • Select the shortest capillary length possible, as changes in ambient
    temperature conditions may significantly affect the accuracy and response time
    of the instrument
  • Standard length 5', others available
  • Installation on analog gauges requires a gauge support and gauge adaptor,
    or other surface mounting provisions
  • Any level difference between the instrument and the seal will result in a pressure indication error; make sure to compensate for the level difference during calibration of the diaphragm seal assembly if the level difference is known
