3.5 Temperature sensor installation instructions
A0008603
å 14 Installation types for temperature sensors
A - B For cables with a small cross-section, the sensor tip must reach to the piping axis or a little farther
(=L).
C - DSlanted orientation.
The immersion length of the thermometer influences the accuracy. If the immersion length is
too small, errors in the measurement are caused by heat conduction via the process connection
and the container wall. For installation in a pipe, therefore, the recommended installation depth
ideally corresponds to half of the pipe diameter.
• Installation possibilities: Pipes, tanks or other plant components
• Minimum immersion depth = 80 to 100 mm (3.15 to 3.94 in)
The immersion depth should be at least 8 times the diameter of the thermowell. Example:
Thermowell diameter 12 mm (0.47 in) x 8 = 96 mm (3.8 in). We recommend a standard
immersion depth of 120 mm (4.72 in).
For pipes with small nominal diameters, ensure that the tip of the thermowell extends far
enough into the process so that it also protrudes past the axis of the pipe
((® å 14, ä 14), item A and B). Another solution may be diagonal installation
((® å 14, ä 14), item C and D). To determine the immersion length or installation depth,
all parameters of the thermometer and the process to be measured must be taken into
account (e.g. flow velocity, process pressure).
See also recommendations for installation EN1434-2 (D), figure 8.

4.1 Connection requirements
!WARNING
Electrical hazard
►The entire electrical connection must be carried out only while the device is de-energized.
!CAUTION
Observe additional information
►Before commissioning, ensure that the supply voltage corresponds to the specification on the
nameplate..
►Provide a suitable switch or power-circuit breaker in the building installation. This switch
must be installed close to the device (so that it is easily accessible) and marked as a circuit
breaker.
►An overload protection unit (rated current = 10 A) is required for the power cable.
