AT30 Skin Type Thermocouple
Brand: Ashcroft IncThe 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
