Technical Data
The intrinsically safe input characteristics of the Mag-FLEX probe are listed below. Refer to the site preparation
procedures in this manual for general instructions on safe installation, use and replacement.
The above values are to be used when assembling a system in the field when for calculating its maximum cable run
(field + sensor cable).
When used in potentially explosive atmospheres, the maximum temperatures depending on the temperature
classes and categories can be found in Table A-1.
