Oven and Food Equipment Applications
- Commercial and electric ovens
- BBQ grills, smokers and baking equipment
- Food processing and cooking machinery
- High-temperature laboratory and industrial equipment
- Temperature control systems requiring stable RTD measurement
Installation and Wiring
The four-wire configuration is suitable for controllers that require lead-resistance compensation and repeatable temperature measurement. Probe length, diameter, mounting method, cable routing and connector selection should be matched to the equipment drawing and installation space.
OEM Customization
Starlight Sensors can customize the PT100, PT500 or PT1000 element, probe dimensions, mounting method, cable material, cable length, connector and wiring configuration. For a technical review, send the operating temperature, installation drawing or sample, required accuracy and expected quantity.
