Example
For instruments fitted with a DIH50 transmitter and digital display, for example, the following
limit for temperature class classification applies:
Temperature class
T6
The permissible ambient temperatures and surface temperatures for third-party products
can be seen from the relevant approvals and/or data sheets and must be observed.
According to approval, these thermometers are suitable for the temperature classes
T1 ... T6. This applies for instruments with or without built-in transmitters and/or digital
displays. Make sure the maximal ambient temperature for the safe use of the instrument is
not exceeded.
1) The values in brackets apply to special designs. These probes are manufactured using special sealing compounds.
Moreover, they feature cases made of stainless steel and cable glands for low-temperature ranges.
