Dwyer 电容式物位开关 NCS-10系列

Series NCS-10 Through Wall Capacitive Sensor features a thin profile with a sensing distance of 10 mm non-flush mounted. The switching points can be altered by means of the push-button teach-in function. 3-wire DC output with selectable make (NO) or break (NC) switching and NPN Alarm. The NCS-10 is designed for front, pipe or plane mounting. Capacitive sensors can detect metallic as well as nonmetallic objects; however, their traditional use is for non-metallic materials such as: plastics industry, chemical industry, wood industry, ceramic and glass industry, and packing industry.
