2 Construction and Tolerances Construction feature flexible SERV-RITE wire insulated with woven fiberglass or high temperature engineered resins. For added protection against abrasion, products can be provided with stainless steel wire braid and flexible armor. ASTM E 230 color-coding identifies standard catalog thermocouple types (see reference chart on inside back cover). The addition of a metal sheath over the thermocouple provides rigidity for accurate placement and added protection of the sensing junction. Mounting options include springs, ring terminals, specialized bolts, pipe style clamps and shims. How to Order Determine style of thermocouple required Complete the eleven digit part number as determined by the following parameters: Construction Diameter Calibration protection unction Sheath length length Terminations/options Note: All eleven spaces must be filled in. Availability Rapid Ship sensors are available for same or next day shipment. Preferred sensor options are available for shipment in approximately three days. For custom built products consult factory for approximate shipment time. 44

20 Melt Bolt Thermocouple Watlow plastic melt bolt thermocouples are designed so that the sensitive closed end portion of the tip can be inserted directly into the plastic stream of an extruder or injection molding machine. The measuring junction is thermally isolated from the metal bolt mass, assuring accurate reading of the melt temperature up to 260 C (500 F) continuous. Bolt is 300 series stainless steel. 62 E in.
