6.1 Replacing the electronics
When it comes to the manufacturer's industrial thermometers, it is only possible to replace an
electronic component if the measuring insert features a temperature transmitter ("head-
mounted transmitter"). Consult the handbook for the temperature transmitter to learn what you
need to take into consideration when replacing the electronics.
6.2 Cleaning and maintenance
As a rule, the manufacturer's industrial thermometers require no cleaning or maintenance.
However, depending on the conditions of use and the thermal and mechanical load, they can age.
This is true of both measuring inserts with Pt100 RTDs and measuring inserts with
thermocouples.
As a result of the ageing process, the characteristics ("characteristic curve") can change. That
means that the relationship between the electrical resistance (measuring insert with Pt100 RTD)
or the thermovoltage (measuring insert with thermocouple) and the temperature changes. In
this case, calibration shows whether any deviations in measurement values are still within
permissible tolerances.
6.3 Spare parts availability
The manufacturer adheres to the basic principle that functionally adequate spare parts for each
device or each important accessory part will be kept available for a period of 3 years after
delivery of the last production run for the device.
This regulation only applies to spare parts which are under normal operating conditions subjects
to wear and tear.
6.4 Availability of services
The manufacturer offers a range of services to support the customer after expiration of the
warranty. These include repair, technical support and training.
