DH-S digital speed detector manufacturers, DH-S digital speed detector Supply DH-S digital speed detector, DH-S digital speed detector price, DH-S digital speed detector adoption TRs belt skid slip detection skid detector of Contact contact speed detector speed detection means the speed detector is a more advanced speed sensing apparatus, includes not only the slip detector function, more effective and accurate display speed data. Is a new type of detector, light weight, easy to transport, long life, no maintenance. This product has been widely used in metallurgy, coal, mining, cement, electricity, food, food and other industries in the belt conveyor, a material handling system to achieve automatic control indispensable monitoring devices. Its advantage candle accurate detection range, advanced technology, light weight, easy to install, small measurement error, degree of protection that can be used to monitor the speed of the conveyor belt when the speed is monitored transport belt is below (above ) when the pre-set value, it can issue a warning or stop signal, which can effectively avoid the accident. Belt speed detector has one (or two) from 1 to 999 rev / min can be arbitrarily set the alarm point. Zmjt11 technical parameters ? Contact capacity: AC220V 2A ? Loop detection: 2 channels, each set of changeover contacts ? Power supply: AC200V ± 20% 2A ? Insulation voltage: AC200V test machine one minute ? Power consumption: ≤10W ? Reliability: 25,000 hours between failures ? detection with speed range: 0-99.9m / s ? Detection speed range: 0-99.9r / s ? Detection speed error: ± 0.04r / s ? Protection: IP65 works DH- working process type speed detector S is detected by sensor head to tape speed or rotational speed in a pulse signal into the control box, in unit of time counted by the counter circuit in the control box, and then with the preset speed or with speed compared to greater than or less than the judge. If the belt speed is greater than or equal to the preset speed, then the control relay. At this point the tape running normally. If less than the preset speed or the speed with the release of the control relay, then tape stall. The product has been exported to many countries, the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran, was unanimously praised by customers.
