➀
Process temperatures based on -40 °to +160 °F
(-40 °to +71 °C).
➁
Bronze models are rated to a maximum process
temperature of +500 °F (+260 °C).
Stainless steel models are limited to the maximum
temperature of the selected switch mechanism.
➂
On steam applications, temperature down-rated
to +400 °F (+204 °C) process at +100 °F (+40 °C)
ambient.
