Temperature Ratings
The maximum temperature ranges stated in this installation guide are only valid if the Hydro-Mix HT is
installed using the supplied mounting system (Fixing Plate and Clamp Ring).
1 Process Temperature Range
The Hydro-Mix HT has been designed to operate in applications where the process temperature
is between 0-120°C. The sensor will operate at intermittent temperatures of up to 130°C to
enable cleaning to take place (maximum 10 minutes).
The Hydro-Mix HT has been designed with additional cooling fins to enable heat to dissipate
quickly. The cooling fins must not be covered and must remain clean at all times to enable
effective cooling.
Additional cooling may be required if the sensors electronics exceed 65°C.
2 Ambient Temperature Range
The ambient temperature around the sensors body will affect the overall maximum process
temperature the sensor can operate in. The maximum ambient temperature for the Hydro-Mix HT
is 53
°
C. However, the upper ambient temperature limit is reduced as the process temperature
increases. The following temperature profile graph indicates the maximum process temperatures
for a given ambient temperature (Figure 25)

3 Additional Cooling
If the temperature of the sensor electronics exceeds 65°C then additional cooling will be
required. Cooling can be achieved by installing a forced air supply. The air should be directed
over the cooling fins and the sensor body.
