Description
The Adjustable J-Type Bayonet Thermocouple is designed for accurate temperature measurement in plastic processing, packaging, and industrial heating equipment where consistent probe contact and installation flexibility are essential. It features a J-Type (Iron-Constantan) thermocouple element, a 100 mm spring-loaded bayonet assembly, and a 14 mm double-cut adapter, allowing the sensing tip to maintain constant pressure against the measurement surface even when installation depths vary. This spring-loaded design improves measurement reliability by ensuring continuous thermal contact during machine operation.
Manufactured with a durable stainless steel sensing assembly and a 40 mm sensing tip, the thermocouple operates over a temperature range of 0°C to +400°C. The FG/FG/SS insulated cable provides excellent resistance to heat, abrasion, and mechanical wear, making it suitable for demanding industrial environments. The longer 100 mm spring offers greater travel than standard bayonet designs, helping compensate for machining tolerances, thermal expansion, and equipment vibration while maintaining stable temperature readings.
The Adjustable J-Type Bayonet Thermocouple is widely used in plastic extrusion machines, injection molding equipment, thermoforming systems, film production lines, packaging machinery, hot runner systems, barrel heaters, dies, and nozzles. Aavad Instrument Pvt. Ltd. also offers customization of spring length, probe dimensions, adapter size, cable length, thermocouple type, and connector options to meet specific OEM and industrial process requirements.
Key Features
-
Extended 100mm Adjustable Spring Mechanism Offers longer compression travel than standard 60mm springs, accommodating deeper or non-standard machined mounting recesses.
-
14mm Double-Cut Bayonet Cap Standardized 2-slot cap locks quickly into standard 14mm bayonet adapter studs with a simple push-and-twist motion.
-
Positive Thermal Contact ($40text{mm}$ Tip) Continuous spring tension holds the sensing tip firmly against the bottom of the well, eliminating air gaps and preventing measurement drift from machine vibration.
-
High-Sensitivity Type J Calibration ($text{Iron / Constantan}$) Provides fast linear response across 0°C to 400°C, ideal for polymer melt zones and hot-runner dies.
-
Armored FG/FG/SS Extension Lead (1m) High-temperature fiberglass internal conductor insulation wrapped in an outer stainless steel wire braid guards against abrasion and flexing fatigue.
-
Fast Tool-Free Installation & Replacement Quick-disconnect bayonet mechanism enables rapid replacement during mold changes or maintenance overhauls.
