Platinum chip temperature sensors belong to the category of temperature sensors that were made using thin-film technology. Wired sensors of type PCW are mainly used in industrial electrical temperature measurement in RTD temperature probes
The PCWR compact design type has connection wires that lead to the center of the sensor. As a result, it is particularly suitable for confined spaces or special probe designs. The PCWRB variant is equipped with a solderable nickel-gold metallization on the back cover. Direct thermal contact to another body can be established via metallization using a solder connection, as a result of which a fast response time can be achieved. One popular application is calorimetric flow measurement. The PCWC design type offers special protection against moisture and condensation with an epoxy coating. The sensors are ideally suited for sensor probes in the field of heating, air conditioning, and ventilation.
Platinum sensors in SMD design type are especially designed for the automatic placement on circuit boards. They are suitable for surface or ambient temperature measurement on circuit boards and are the preferred option for temperature monitoring or compensation circuits. Their small size allows a high placement density. The patented contact technology enables outstanding processing results and a high degree of temperature cycle stability.
The sensors are available in 3 design types by default and differ mainly in the version of the solder contacts. The SMD design type has a contact on the reverse side (wrap-around contact), while the solder contact on the SMDFC design type (flip chip) is on one side. In addition, the SMDFCB variant is available with a solderable, metallized back cover.
The AEC-Q200 specifies electrical standards and test procedures for use in the harsh automotive environment. It provides evidence of the reliability and quality of electrical components. Selected SMD sensors from JUMO are qualified according to the standard, so that efforts for further qualification tests at the component level are reduced.
A popular use of SMD sensors is the construction of measuring inserts for temperature probes. A circuit board is automatically equipped with the SMD sensors to form a preassembled measuring insert that can be slid into a thermowell. Such probes are used, for example, in large numbers for heat quantity measurement.
JUMO offers standard measuring inserts with PCB design type. However, an application-specific layout is often required. We will happily support you in finding a suitable solution for your application.
