CAUTION!
Damage to the instrument
In thermometers with a built-in microswitch, the contacts can chatter as a
result of vibrations, which can lead to an increase in contact wear and a
displacement in the desired contact point.
▶
Mount the indicator case free from vibration.
▶
If necessary, it is possible to isolate the thermometer from the mounting
point, e.g. by installing a flexible connection line between the measuring
location and the instrument and mounting the instrument on a suitable
bracket.
Electrical connection
The pin assignment are given on the product label which is located around
the edge of the case.
5.1
Ambient conditions
To ensure the best measurement accuracy possible, the ambient temperature on the
indicator case should be between -20 ... +50 °C [-4 ... +122 °F]. Higher or lower ambient
temperatures can cause indication errors specified in EN 13190 class 1 to be exceeded.
5.2
Installation conditions
Before mounting the probe, check whether the probe material used (specified in the
delivery note) is chemically resistant/neutral to the medium being measured.
The accessories are either fitted or located in a bag fastened to the thermometer.
5.3
Mounting the probe
If possible, the entire length of the stem should be exposed to the temperature being
■
measured. However, at least the length of the active part that corresponds to the
length of the expansion vessel (active length).
In pipelines or other measuring locations, the temperature probe must be positioned
■
as far towards the flow as possible.
Protect capillaries against bending. The smallest bending radius of the capillary
■
should not be less than 6 mm. Any bending or discontinuities of the remote capillary
may result in the failure of the instrument.
The transport safety on the compression fitting in the shape of a rubber ring must be
■
removed before mounting the probe.
