Obsolete Product . . .
Contact M&M for options
or current availability.

The Partlow Piston Pak is a fluid filled, hermetically sealed, stainless steel sensing element connected through a temperature compensated stainless steel capillary to a piston-cylinder arrangement. These sensors are rugged, reliable, sensitive, and accurate to within 1%. The capillary requires no armoring and the sensors are easily replaced in the field. Sensors cover the operating ranges from -30° F to 1100° F (-35° C to 600° C). Stainless steel element sleeves and capillary bushings are available, as well as Teflon and Geon element and capillary coatings.
