German SPM sensor SPM model SPM price

SPM sensors are components that convert changes in non-electrical quantities (such as speed and pressure) into changes in electrical quantities. Depending on the non-electrical quantity being converted, they can be classified as pressure sensors, speed sensors, temperature sensors, etc., and serve as parts and accessories for measurement and control instruments and equipment. The SPM sensor structure consists of two parts: the scale grating and the grating readhead. The figure on the right shows the structure of the grating scale. The key part of the grating detection device is the grating readhead, which consists of a light source, condenser lens, index grating, photoelectric elements, and adjustment mechanisms. There are many structural forms of grating readheads.
