External Chamber Sealed or Flanged Top DESCRIPTION The Magnetrol ® external chamber is a self-contained cage designed for use with our top mounting level transmitters or switches. Quality construction and a wide selection of configurations make this cage an ideal means of utilizing the power of our many technologies without mounting directly into the process vessel. The chamber is suitable for use with Eclipse® Guided Wave Radar and Kotron ® RF Capacitance transmitters, all electronic point sensors and top mounted displacer switches.

To properly size your sensing element when mounting in a flange top chamber, it is necessary to determine the dimension from the face of the head flange to the centerline of the upper process connection. To determine this dimension: 1. Use the third, fifth & seventh digits of your chamber model number and the above chart to verify the type of head flange on your chamber. 2. On page 5, locate the ‘A’ dimension of your chamber according to the chamber pressure rating, head flange type, design standard, chamber size & process connection size. 3. Go to the formulas on page 6 for probe or cable lengths. Using your ‘A’ dimension and measuring range (customer designated), determine your required probe length.
