Датчик предельной ёмкости Capacitive limit switch LCL* Pepperl+Fuchs

Описание товара

Application
Function principle		Limit detection Maximum or minimum detection in silos with all types of solid granulates, even in dust explosion hazardous areas.
Function and system design
Measuring principle		A metal plate at the end of the probe, within the insulation, and the surroundings (e. g. the silo walls) combine to form the two electrodes of a capacitor. If the probe is covered or free of material, then the capacitance changes and the LCL switches.

Operating conditions
Installation conditions
	Installation position	LCL1: optional LCL2: vertically down Note the angle of the material mounds and the outlet funnel when determining the mounting point or probe length. The limit switch switches when the probe tip is covered by a few centimetres of material or when it is free material flow should not be directed at the probe.
	Mounting location	The capacitive limit switch can be installed in silos made of different materials (e. g. metal, plastic, concrete).

Важная информация

Все информационные материалы, представленные на сайте, носят справочный характер и не могут в полной мере передавать достоверную информацию о свойствах и характеристиках товара.

Фотография на сайте служит дополнительным источником для определения совместимости запчастей с Вашим оборудованием, и не может являться основным. Основной источник по совместимости запчастей - актуальная документация производителя оборудования, из которой значимой информацией для заказа являются: название запчасти и каталожный номер.

Запасные части и комплектующие подбираются самостоятельно покупателем строго по каталожным номерам из официальных деталировок производителей. В случае, если номенклатура товара совпадает с фактически поставленной, но не подходит на оборудование - в ее замене или возврате может быть отказано.

Цены на сайте имеют информационный характер и могут отличаться от цен в коммерческом предложении.
