Hello TechNetters... We're X-Raying our thermal fuses now for more thorough observation of potential failures, but due to multiple mfgs of thermal fuses, we're wary right now that our standards may not be quite so standard... I'm researching this myself, but maybe one of you out there could help me get started on this: Thermotrol PN: DF915 Looking for thermal pellet starting width Looking for degradation tolerance Thermodisc PN: Q4A00098C Looking for thermal pellet starting width Looking for degradation tolerance Ecmsen PN: D090-002 Looking for thermal pellet starting width Looking for degradation tolerance We have several precision-set thermo-monitors with cut-off alarms running on the prod. line in conjunction with the X-Ray machine, but want to acquire some more standards info... I'll be looking up url's shortly, and going thru catalog inventories... Any assistance on this matter would be greatly appreciated! John Grabski III Engineering Tech.
