Description

The TC46 series thermocouples are custom-designed to suit all applications where sheathed thermocouples are required. An extensive range of elements, transition sleeves and process connections can be individually selected for the appropriate application. With the flexibility and small diameters in which they are available, model TC46 thermocouples can be used in locations that are not easily accessible.

Thanks to their unique design, the hot runner thermocouples are especially suited for applications where the metal sensor tip is fitted directly into a drilled hole or press-fitted into a grooved channel along the machined parts.

Hot runner thermocouples, model TC46

In the standard version the thermocouples are manufactured without process connections. Fastening elements such as a union screw, a compression fitting, or a spring-loaded or customer-specific hold down device can be attached and are available as options.

Special features

Exclusion of potential faults during installation and operation in hot runner systems thanks to plasticencapsulated transition
The thermocouple can be installed without any fixing through bending or forming the sheathed cable or with a rotatable (if required, spring-loaded) union screw
Probe diameter 0.5 ... 3.0 mm [0.020 ... 0.118 in]
Kapton ® , as the industry standard insulating material for connection cables

Sheathed cable

Design	Mineral-insulated cable (sheathed cable) Thermocouple wires embedded in highly compressed ceramic powder
Max. permissible bending tolerance in accordance with ASTM E839 - 8.5.2 standard	Can be closely wrapped three full turns on a mandrel with a diameter twice the sheath diameter
Diameter	■ 1.5 mm[0.059 in] ■ 1.6 mm[0.063 in] ■ 0.5 mm[0.019 in] ■ 1.0 mm[0.039 in] ■ 2.0 mm[0.079 in] ■ 3.0 mm[0.118 in]
Material	Stainless steel ■ Up to 800 °C [1,472 °F] (air) ■ Good resistance against aggressive media and also against vapour and combustion gases in chemical media

Transition
Version	■ Plastic-moulded ■ Brazed ■ Crimped ■ Embedded in potting compound Further customer-specific versions on request Note:
Plastic-encapsulated transition	■ A unique design highly recommended and used in the hot runner industry ■ The transition, which is plastic-encapsulated at high temperatures, eliminates all potential issues that may cause failures during installation or production processes. ■ The plastic-encapsulated transition eliminates moisture leakage into the sheathed cable or connection leads.
Tensile strength	Up to 9 kg [20 lbs]
Dimensions	Ø5x20 mm[0.197 x 0.787 in]

Connection cable
Version	Jointly insulated individual strands, ready for connection
Cross-section	Min. 0.20 mm² [24 awg]
Cable length	1,000 mm[39 in] with additional intervals of 500 mm[20 in]
Other lengths on request
Insulating material	Kapton ® / Kapton ®	Polyamide tape sheath for improved electrical properties and high-temperature applications.
	Polyamide tape sheath for excellent abrasion and perforation resistance and very high resistance to moisture and chemicals.
	Glass fibre / glass fibre	Wound glass fibre insulation for improved moisture and abrasion resistance at high temperatures.
	Braided glass fibre for additional flexibility and abrasion resistance at high temperatures.
	PVC / PVC	PVC insulation for cost effectiveness, durability and mechanical strength
		PVC jacket for cost effectiveness, durability and mechanical strength. It is also tough and resistant to heat, abrasion and moisture.
	PTFE / PTFE	PFA insulation for improved electrical properties and high-temperature applications.
