Surface Mount.
Thermocouples engineered to measure the surface temperature of machinery, engines, tubes and vessels — gasket, bayonet, tube-skin and magnetic styles, in standard and CERAMO® high-temperature construction.
Surface Mount Thermocouples
Seven constructions for reliable surface temperature measurement
Each style is designed for a different mounting need — from permanent gasket and tube-skin attachment to quick-release bayonet and magnetic contact. Select a construction below and download its datasheet.
Gasket Thermocouples
Attaches to a stud welded to the surface, or with a nut and bolt. The measuring junction is effectively the entire gasket area — most often used to monitor the surface temperature of machinery and engines.
High Temperature Gasket Thermocouples
A CERAMO® tip on the gasket provides a higher temperature range and a more durable, bendable construction. The sheath can extend from a few inches to any length, and allows an ungrounded measuring junction.
Bayonet Thermocouples
A quick twist of the bayonet locking cap gives easy installation and removal, with positive tip contact regardless of surface expansion and contraction. A variety of mounting adapters suit different machine designs.
High Temperature Bayonet Thermocouples
Manufactured with CERAMO® for a higher temperature range and more durable construction, especially in moisture-prone areas. Also allows an ungrounded measuring junction.
Adjustable Length Bayonet Thermocouples
Adjustable by hand-twisting the cap — eliminating the need to stock many fixed immersion lengths. Available in rigid sheath or flexible armor.
Tube Skin Thermocouples
For permanent attachment, especially suited to lightweight applications where the heavier industrial tube-skin construction isn't needed.
Magnetic Thermocouples
Measures the surface temperature of any magnetic object — ideal where quick removal is needed or the surface can't be modified. Spring-loaded, with grounded or ungrounded flat-tip construction; temperature limited to the magnet's holding power (approx. 400°F).
