Weller’s WCU High-Precision Temperature Measurement Device Provides Fast Measurements with High Levels of Accuracy

Weller WCU mobile high-precision temperature measurement device

A professional control unit that controls soldering and reworking tools must ensure the precision of its working parameters. Some technologies have individual settable temperatures, in step increments of 1° while others work with fixed temperature tips. In both cases, it is crucial that the actual working temperature ensures a safe,repeatable process. The advanced Weller professional soldering technologies use a closed–loop temperature regulation to monitor the temperature of the tip via a high-quality Platinum sensor. It automatically adjusts the power to the silver core heating element according to the application, component and solder joint size. As the Weller® heater design continuously maintains the same physical material characteristics during its lifecycle, no calibration is required. The Platinum sensor and the control technology ensure temperature accuracy and stability according to IPC J-STD001 D. For advanced precision, surpassing IPC J-STD-001 D temperature accuracy requirements, all the professional digital units manufactured by the German company in the last 20 years have a built-n OFFSET function, which sets a value to correct any slight deviations (due to the specificity of the tip or to the state/wear or shape of it).

As an alternative (or addition) to the thermo cross, a type K thermocouple can be connected to carry out temperature measurements of any type: from a solder bath or a process, or even to verify “system accuracy” regardless of the specific tip used, but based on a sample tip, and this would use the 0.5 mm probe together with the appropriate Weller measurement tip (sold separately, T0053119099). The temperate read by the external sensor is shown in the top left corner of the display.
