Switch contact model 831
The built-in electrical inductive contacts are non-contact slot-type
inductive proximity sensors, which are powered from isolating ampliers
with certied intrinsically safe circuits. On exceeding the adjustable limit
values, their output circuits are either opened or closed.
2.3 Scope of delivery

Information
... points out useful tips, recommendations and information for
ecient and trouble-free operation.
3.2 Intended use
The instruments serve for temperature measurement in the chemical
and petrochemical industries, oil and gas industries and also for the
energy and shipbuilding industries.Through the high ingress protection
of the thermometer (IP65) and its liquid dampening, operation under
high vibration conditions is possible. In addition they full the high
requirements for resistance against aggressive media.The contact
thermometer, with up to 3 integrated model 831 inductive contacts,
displays the process temperature on-site and opens/closes circuits at
dened temperature values.
The instrument oers many application possibilities for gaseous and
liquid aggressive media that are not highly viscous or crystallising.
Only use the instrument in applications that lie within its technical
performance limits (e.g. temperature limits, material compatibility, ...).
→ For performance limits, see chapter 9 “Specications”.
The instrument has been designed and built solely for the intended use
described here, and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
