Operating conditions Platinum-chip temperature sensors may not be used unprotected in humid ambient
conditions or corrosive atmospheres. They must also not be immersed directly in liquids.
The user may have to carry out some checks before operation.
Please also refer to the Installation Instructions B 90.6121.4 “Notes on the
application of platinum-chip temperature sensors.”
Connecting wires These temperature sensors feature connecting wires that are made from pure silver. The
connecting wires are especially suitable for soft-soldered joints. During further
processing, it is essential to ensure that the connections are not subjected to lateral
pressures. The horizontal tension on the individual connecting wire must not exceed the
maximum value of 5N. Any unnecessary bending of the connecting wires must be
avoided, as this may result in material fatigue and a wire break. Please also refer to section
3 “Connection methods” in our installation instructions. Longer connecting wires up to
300mm length (in one piece) can optionally be fitted. Alternatively, extensions of any
length or insulated stranded wires can, on request, be fitted at a later stage.
Measurement point The nominal value specified refers to the standard connecting wire length L1. The
measurement is acquired 2mm from the open end of the wire. If the wire length is altered,
changes in resistance will occur which may result in the tolerance class not being met.

drift 0.05%/year (see Data Sheet 90.6000 for definitions)
Low-temperature application Taking into account nominal value drifts and hysteresis effects that may occur within
certain limits, temperature measurements down to -200°C are also possible. Further
details can be obtained on request.
Insulation resistance >10MΩ at room temperature

Packaging Blister belt/bag
Storage In the standard belt packaging, JUMO temperature sensors, PCA/L style, can be stored
for at least 12 months under normal ambient conditions. It is not permissible to store the
sensors in aggressive atmospheres, corrosive media, or in high humidiy. Since the
connecting wires for this version are made from pure silver, storability is enhanced by air-
tight packaging and dark surroundings. If this is not the case, the silver will tend to get
tarnished with time, which may lead to difficulties when making the solder joint.
