Why choose FB9x series self-aligning machineresolver-absolute shaft angle encoder

Self-aligning machine/resolver, known for its high precision and high reliability, is mainly used in places requiring high accuracy and reliability, such as aviation, aerospace, ships, weapons, radar, fire control, missile control , Communications, etc. Compared with other types of shaft angle encoders, the self-aligning machine/resolver type has obvious advantages:

⑴ From the performance point of view: Since there are no electronic components inside the auto-aligner/resolver, there are only two sets of coils, so its vibration resistance, temperature resistance, corrosion resistance, dust and oil pollution, and interference resistance It has very good performance, can adapt to the requirements of any environment, and has extremely high reliability. The photoelectric type, grating type, and magnetoelectric type have many electronic components due to the integrated processing circuit inside the sensor, which is greatly affected by vibration, temperature, corrosive gas, dust and oil, and the photoelectric type is also affected by the life of the light source Influence, its anti-interference performance is not as good as self-aligning machine and resolver.

⑵ From the point of view of use: the installation size has a large choice of space, which can be from 20mm to 80mm in diameter, and the outline size is not affected by the resolution; the sensor and the data processing part only need 5 connections, eliminating other types of encoders The trouble of connecting 10 to 20 lines; the sensor has no absolute zero position, and any position can be used as the zero position for measurement, eliminating the trouble of adjusting the zero position of the sensor; high measurement capability, can measure up to 30,000 cycles.

⑶. From the measurement accuracy point of view: FB9x series angular position transmitters, the single-turn resolution can range from 8 to 16 bits (that is, 360 degrees is divided into 256 to 65536 parts); the tracking speed is high, which can reach 6000 rpm ( For 400Hz sensors).

⑷ From the point of view of function: various interfaces are complete, and it is very convenient to connect with computers or other equipment. FB900C has angle and position conversion function, users can program it, 4-20mA output, RS232C or RS485 output; FB900P has 20-bit parallel port angle output, which is convenient to connect with PLC or other equipment; FB900D has RS232C or RS485 output , Communication parameters can be set by users; FB900V has both angular position and speed output, and users can program it. There are two 4-20mA outputs, RS232C or RS485 outputs. The product we have developed is also the FB920 series dual-speed shaft angle converter, with 4-20mA output, RS232C or RS485 output.

⑸ From the price point of view: After years of painstaking research, our company has overcome many difficulties, cancelled the traditional SCOT transformer and SD converter, adopted newer and more advanced methods to calculate the angle, improved the conversion accuracy, and reduced Cost, to provide users with a very competitive price of high-performance products.

In summary, due to the use of the FB9x series of self-aligning machine/resolver-absolute shaft encoder has good performance, high precision, extremely high reliability, wide use environment, and low price, it can be completely replaced Other types of absolute shaft encoders can improve the performance and market competitiveness of customers' own products.
