3.0 Functionality
3.1 Functional description
The sensor can be used for measuring temperature
in the range -50°C to 400°C (-58°F to 752°F).
Sensors may be supplied with certificates for a
limited temperature range.
The resistance of the JOFRA STS-103 B sensor is
converted to temperature according to IEC-751 (ITS-
90) (calculated coefficients specific for the sensor
are stated on the certificate).
3.2 Connections
The sensor is delivered with a connecting cable and
with the following options:
