PCA/S Platinum-chip Temperature Sensors

MOQ: 100PCS
All sizes available
Samle available

Quantity:
  • PAC/S style
  • JUMO
Description: 

Platinum-chip temperature sensors, S version, are mainly used for applications at temperatures above 180°C. They are particularly suitable for electrical connection through weld/crimp or hard-soldered joints. The connecting wires consist of a solid sheathed platinum wire and exhibit high strength. The application temperature ranges from -70 to +400°C.

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.

Connecting wires

These temperature sensors feature connecting wires made from sheathed platinum wire with a nickel core. The connecting wires are suitable for crimp/weld and hard-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 10N. Any unnecessary bending of the connecting wires must be avoided, as this may result in material fatigue and a wire break. Longer connecting wires up to 300mm length (in one piece) can optionally be fitted. Alternatively, silver wire or insulated stranded wires of whatever length is required can be used as extensions at a later time. Please note, however, that there may be restrictions on the application temperature.

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.

Long-term stability

max. R0 drift 0.05%/year

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

Self-heating

t = I2 x R x E

Packaging

Blister belt/bag

Storage

In the standard belt packaging, JUMO temperature sensors, PCA/S 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 humidity.
