Scope of use
The LJK series of feedback probes produced by our factory are used in chemical water treatment systems, ash removal systems, acid and alkali in power, petroleum, chemical, metallurgical and other enterprises. Signal feedback from various domestic and imported equipments in metering systems, condensate systems, lime water systems, upgraded products of various types of travel switches such as boiler soot blowing, ignition, pumping, exhaust, electric gates, etc. Monitoring display.
Performance Features
(1) This product uses SMT assembly technology to reassemble various micro components, and the contacts are non-magnetized, wear-free and fatigue-resistant;
(2) Signaling is a non-contact action with no mechanical failure. Submersible, double-layer fully sealed structure, non-oxidizing, moisture-proof, waterproof, acid and alkali corrosion resistant, safe and explosion-proof performance;
(3) The contact is fully suffocating, no power supply is required, leakage current, residual voltage is zero, and the proximity switch is solved in programmable controller, PLC, DCO Problems such as “out of signal” and “missing error” caused by leakage current and voltage drop during operation in the system;
(4) Feedback probe is easy to install and debug, no tools, just move the position by hand, long service life, once installed, no maintenance for life ;
(5) With built-in inch threaded interface, it can be connected to various specifications of metal joint bushings.
