Application conditions Platinum chip temperature sensors must be protected when used in a humid environment or in
aggressive atmospheres. Direct immersion into fluids is also not permitted. The user should
check the conditions, prior to using the sensors.
Please also refer to the installation instructions B 90.6121.4 "Information for the applica-
tion of platinum chip temperature sensors.“
Connecting wires These temperature sensors are equipped with connection wires made of a platinum wrapped
wire with a nickel core. The connection wires are suitable for crimp, welded and brazing con-
nections. For further assembly, avoid lateral pressure load acting on the connections. Ensure
that the horizontal pull on individual wires does not exceed 10N. Avoid unnecessary bending of
the connection wires because this will weaken the material and lead to cable breakage. Please
also refer to point 3 "Connection techniques“ in our installation instructions. Longer connection
wires up to a length of 300mm (in one piece) can be optionally fitted. Extension wires made of
silver or insulated strands in any lengths can also be retrofitted as an alternative. In this case,
however, take into account that this may result in restrictions concerning the application tem-
perature.
Measuring point The specified rated value is related to the standard connection wire length L1. The measured
value is taken 2 mm in front of the open wire end. Wire length extensions could lead to resis-
tance changes as a result of which the tolerance class can no longer be met.

drift 0.05%/Year (for definition, see data sheet 90.6000)
Low-temperature application Taking an occurring rated value drift and hysteresis effect within certain limits into account, tem-
perature measurements are also possible up to -200°C. Further details are available on request.

Packaging Blister belt/bag
Storage In their (standard) belt packaging, JUMO temperature sensors of the PCA/S design can be
stored for at least 12 months under normal ambient conditions. Storage in an aggressive atmo-
sphere or in corroding media as well as under high air humidity is not permitted.
