Description of thermocouple:
Thermocouple consists of two conductors of different materials
(usually metal alloys) that produce a voltage in the vicinity of
the point where the two conductors are in contact. The voltage
produced is dependent on, but not necessarily proportional to, the
difference of temperature of the junction to other parts of those
conductors. Thermocouples are a widely used type of temperature
sensor for measurement and control and can also be used to convert
a temperature gradient into electricity.
Features of thermocouple:
• Customized diameter, sheath lengths and lead length
• Stainless steel braided or hose protection
• K, J, T and E calibrations
• Grounded, ungrounded and exposed junctions
• Flat and drill point
• Epoxy sealed cold ends
• Flexible extensions
• Miner coated and stainless steel sheaths
• Straight, 45° bend or 90° bend
• 12 mm and 15 mm locking bayonet caps
Performance Capabilities of thermocouple:
Maximum Temperature Tolerance of thermocouple with glass fiber
insulation: 600 cent degree for non-stop working.
Maximum Temperature Tolerance of thermocouple with mineral fiber
insulation: 1500 cent degree non-stop working.
Temperature test precision: +/-1 cent degree
Applications of thermocouple:
• Food processing equipment
• De-icing
• Plating baths
• Industrial processing
• Medical equipment
• Pipe tracing control
• Industrial heat treating
• Packaging equipment
• Liquid temperature measurement
• Refrigerator temperature control
• Oven temperature control
