AT20 Thermocouple
Brand: Ashcroft IncDoes not ship to OH, United States
The Ashcroft AT20 temperature sensor assemblies provide accurate temperature measurements for applications that are located in hazardous environments.
Each temperature sensor assembly consists of a spring loaded temperature sensor, magnesium oxide, MgO, insulated insert, connection head and lag extension.
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 and RTDs assemblies are manufactured to IEC 60751.
Features- Designed for DIN 43772 thermowells
- Manufactured to 60584-2, or ANSI MC 96.1
- Designed to be used with ISA-ds 49 style thermowells
