An economical way to provide access for instrumentation is to specify an over-sized gap between the heater ends. A hole in the sheath should be specified only when the entire cylinder surface (adjacent to the hole) must be heated.
When required,one hole may be provided in almost any location – as long as there is at least a 25 mm (1 in.)distance between the hole and one side of the heater. Standard hole sizes up to 51 mm (2 in.) diameter. Consult original factory manufacturer for limitations.
Note: For proper hole designation, a dimensional drawing is required with your band heater order.
