INJECTION MOLDING NOZZLE TYPE
In-Melt type thermocouples and RTDs are designed to bolt into the injector nozzle and sense the temperature of the melt directly, and is rated to 450°C (900°F). The standard 3/8" hex head stainless steel body has 3/8-24 NFT threads. The sensor tip extends 1/8" beyond the end of the bolt assembly.
Not In-Melt type thermocouples and RTDs are designed to screw into a blind hole in the nozzle, and is rated 450°C (900°F). The standard 1/4 NFT thread fits most standard nozzles.
EXTRUDER BOLT TYPE
Designed for direct mounting into extruder barrels, the Bolt Type thermocouples and RTDs offer easy interchangeability. Standard configuration has a 1/4" penetration into the barrel, and industry standard 1/2-20 NF thread. Order options allow barrel penetrations of 0 inches (flush) to 1 inch in 1/100th inch increments (specify as A dimension) and flex extension in 1 inch increments (specify as B dimension).
Mineral Insulated Thermocouples and RTDs are known for their excellent mechanical durability and resistance to electrical breakdown. Available in outside diameters from 0.020" (0.5 mm) to 0.500" (12.7 mm), Mineral Insulated Thermocouples can be bent to most any angle without special equipment. Because of its flexibility, the mineral insulated material can be made to extremely long lengths, coiled for inexpensive shipment, and straightened upon arrival without damage.
Ungrounded and exposed junctions are electronically isolated from the sheath. Minimum resistance is 1.5 megohms at 500 VDC.
Due to the varying sized of connection wire and cable, a transition fitting is used between the cold end of the sheath and the connecting wires. This fitting measures 1-1/4" long by 1/4" outside diameter for 1/8" or smaller sheaths, and 1-1/2" long by 3/8" outside diameter for 3/16" and 1/4" sheaths. Larger sheaths are usually connected to bushings or connector heads, and usually do not require transition fittings. Sheaths terminating connectors other than wire or cable do not require transition fittings
Precision RTD (Resistance Temperature Detector) offers excellent accuracy and stability over a wide temperature range. Industry standard 3-wire 100 ohm (DIN) probes are available in 6" (15 cm), 12" (30.5 cm) or 18" (46 cm) sheath lengths with 30" (76 cm) extension cable and spade lug terminals.
The Series TE Duct and Immersion Temperature Sensor can be used to monitor air or water temperature throughout a building management system or an air handler unit. Flanged duct sensors monitor the supply or return air and provide a thermistor or RTD output to the digital controller. Immersion sensors which are supplied with compression fittings are typically used to monitor the hot or chilled water lines throughout a building. Thermowells are recommended, but not required on the immersion sensors.
For variable air volume applications, the Series TE can be configured to have 8' plenum rated cable with flying leads. Standard units come with 4" leads with an integral terminal block to eliminate carrying extra wire nuts. For housing models, multiple knockouts provide easy conduit access to any side of the housing. The 1/4 turn lid comes with a chain to prevent it from being lost during installation.
