AT30 Skin Type Thermocouple

Brand: Ashcroft Inc
Does not ship to OH, United States

The Ashcroft AT30 skin type thermocouple assembly provides accurate surface and wall temperature measurements for applications that are located in hazardous environments. 

Each thermocouple assembly consists of a spring loaded thermocouple, magnesium oxide, MgO, insulated insert, a connection head, lag extension, expansion loop, and weldable sensor.

The assembly may also include an optional terminal block for wiring and/or transmitters. 

Thermocouple assemblies are manufactured to either to IEC 60584-2 or ANSI MC 96.1.
Features
  • Weldable sensor head
  • Available with and without transmitters
  • Integrated expansion loop allows for expansion and contraction within temperature changes
