What is the JB series gate opening sensor
The JB series gate opening sensor is composed of an encoder, a shifting gear, a bracket, a flexible coupling and the like. As a whole is organic, all-digital angular displacement with more precision technology, linear displacement sensors, mainly for water, electricity, chemical, oil and automatic measurement of the automatic control system, especially for hydroelectric power plants, the accumulator Lifting measurement and control of gates such as dams and ship locks. The JB series gate opening sensor converts the actual mechanical parameter values ​​into electrical signals. These electrical signals can be processed by counters, tachometers, PLCs and industrial PCs through different conversions . The encoders selected have the following distinctive features.
1 . The encoder adopts a deformed code contact type shaft encoder and belongs to an absolute value multi-turn digital encoder. In positioning control applications, absolute encoders eliminate the computational task of electronic receiving devices, eliminating the need for complex and expensive input devices. When the machine fails or is powered off, the current position value can be utilized as long as the machine returns to normal operation without returning to the position reference point.
2 . Since the dual-level code wheel is adopted, the code system of the low-order disk and the high-order disk adopts the Gray code, and the low-order disk adopts the deformation code method for the carry-in of the high-order disk, instead of the high-order disk composed of the inner and outer code channels which are commonly used in the past, The small volume and wide measuring range eliminate the coarse error in the whole range, and the data output line is reduced a lot, which saves the engineering transmission cable.
Practice has proved that the JB series gate opening measuring sensor developed by our company has the advantages of high precision, high reliability, strong anti-interference ability, convenient reading, long life, corrosion resistance, convenient installation and use, etc. Photoelectric sensor is incomparable     Â
