Thermocouple Holes/‘U’ Slots/Cutout
Normally required for clearance of the thermocouple probes or holding bolts. Oversize gap can in many cases serve the same purpose, using the centre of the gap as a starting point, specify location in terms of degrees and size of the hole or cut-out. Minimum of ½” is required from the hole to the edge of the heater. For critical hole or
cut-out locations, please provide detailed drawing.
All Thermocouple Holes for Band Heaters (if required) will be Provided at center of width either at 1800 opposite the Clamping or 900 from Clamping, unless specified along with drawing.
Note: As far as possible please avoid thermocouple holes. Try and locate them in the heater gap, since holes in the heater body complicates the internal wiring resulting in less heating area and also turns out to be more expensive.
Oversize Gap: The nominal gap between the clamping is 5-10mm. If a larger gap is required for probes or thermocouples, specify when ordering.
