High temperature sensors my be used for temperature up to 120 °C.
A short-time overload up to 135 °C is allowed; within this time the switching
point is not specified. After returning back to temperatures below 120 °C the
sensor will work properly again.
Amplifiers required: SKM..., SKZ..., see page 1.54 - 1.56
