4.3 Sensor Temperature Considerations
The sensor may be ordered with one of three process temperature ranges:
1. -40ºF to 250ºF (-40ºC to 121ºC)
2. -40ºF to 450ºF (-40ºC to 232ºC)
3. -40ºF to 800ºF (-40ºC to 426ºC)
Note: For the process temperatures in the range of 233ºC - 426ºC, a high temp probe must be used.
The maximum allowable ambient temperature at sensor housing is 70ºC.
