10.3 Disposal
Incorrect disposal can put the environment at risk.
Dispose of instrument components and packaging materials in an environmentally
compatible way and in accordance with the country-specific waste disposal regulations.
Do not dispose of with household waste. Ensure a proper disposal in
accordance with national regulations.
11. Specifications
Measuring insert
Versions
Vibration-resistant, sheathed measuring cable (MI cable)
Optimal heat transfer
Requirement
■
Correct measuring insert length
■
Correct measuring insert diameter
Bore diameter of
the thermowell
Max. 1 mm [0.04 in] larger than measuring insert diameter
Joint width
For joint width > 0.5 mm [> 0.02 in] between thermowell
and measuring insert:
→ Negative impact on heat transfer
→ Unfavourable response behaviour of the thermometer
Insertion length
When fitting the measuring insert into a thermowell, it is very important
to determine the correct insertion length (= thermowell length for bottom
thicknesses of ≤ 5.5 mm [≤ 0.22 in]). In order to ensure that the measuring
insert is firmly pressed down onto the bottom of the thermowell, the insert
must be spring-loaded (spring travel: 0 ... 10 mm [0 ... 0.39 in]).
Spring travel
Spring-loaded plate
max. 10 mm [0.39 in]
Self-gripping spring
max. 20 mm [0.79 in]
Operating conditions
Ambient and storage temperature
-40 ... +80 °C [-40 ... +176 °F]
Vibration resistance
The information on vibration resistance refers to the tip of the
measuring insert.
→ For detailed specifications on the vibration resistance of Pt100
sensors, see Technical information IN 00.17 at www.wika.de.
Standard
6 g peak-to-peak, wire-wound measuring resistor or thin film
Option
■
Vibration-resistant probe tip, max. 20 g peak-to-peak, thin-film
measuring resistor
■
Highly vibration-resistant probe tip, max. 50 g peak-to-peak,
thin-film measuring resistor
