The established range of Labfacility thermocouple and PRT sensors meet the needs of virtually any application.
Standard configurations or custom made assemblies are offered in all of the widely used calibrations, type J,K,N,R,S and B. The choice of standard sheath materials include stainless steel, Inconel (trade mark), Nicrobell (trade mark), recrystallised alumina and silicon carbide; other materials are available to special order.
Depending on the choice of sensor type and sheath materials, temperature ratings of up to 1750oC are available with single or duplex elements.
The comprehensive selection of mineral insulated thermocouples now features 0.5mm sheath diameter versions in addition to 1.0mm, 1.5mm, 3.0mm and 6.0mm. The 0.5mm diameter thermocouples combine low thermal mass and fast response to temperature changes with durable construction; they are highly flexible and their use minimizes process intrusion.
Mineral insulated PRT sensors are now available in a range of diameters and configurations to meet the need for high accuracy, high stability, sheath flexibility and robust construction.
Labfacility offers a wide range of high quality Pt100 and Pt1000 sensing resistors in wire-wound and thin-film types. New additions to the range include surface mount versions and glass encapsulated types for those applications requiring the highest stability and hermetic sealing.
All Pt100 sensors comply with IEC751 and, depending on construction, are available in Class A, B and 1/3, 1/5 and 1/10 DIN tolerances. Dimensions range from sub-miniature to 50mm length to suit any application and optional extended terminations are available to order.
The new, low-cost surface mount device provides an accurate and stable alternative to thermistor beads with the advantage of a universal world standard Pt100 interface with a virtually linear characteristic over a wide range, -50oC to 130oC.
All thermocouples comply with cable colour codes and tolerances to IEC 584-3 as standard but alternatives can be specified. A family of compensating thermocouple connectors manufactured by Labfacility is also available from stock.
Labfacility also offers a wide range of components and fittings for sensor installation and manufacture.
These include pot seals for mineral insulated thermocouples, bayonet caps and adaptors and closed end protection tubes. Additional components include compression glands, melt bolts, thermowells and a wide range of terminal heads.
The established range of "own-manufacture” thermocouple connectors, head and barrier terminal blocks are available for all of the popular thermocouple types. Large stocks of wirewound and thin film platinum resistance thermometer elements are held in Pt100 and Pt1000 versions.
Other products available include thermocouple cables, stainless steel armour for cable protection.
