Many variations of each type are available to meet your application needs. The bare wire and bead construction normally requires additional protection from the medium being measured. The mineral insulated system however can be used on its own, except in particularly severe conditions such as in aluminum or brass foundries.

* Insulated wire thermocouples are suitable for most general purpose applications.

* Bare and ceramic insulated elements, available in ASTM  Types K and J, can be twisted or butt welded. Choices include straight or angle types, two- or four-hole insulators and single or dual element.

* Thermocouple with protection comes complete with head, block and protection tube. Several styles are available.

• Metal processing such as aluminum, zinc, brass (with appropriate protection tube)
• Chemical Industry
• Petrochemical Industry
• Industrial storage tanks
