RHM0330MD631P102 American MTS Encoder*

Our company supplies MTS, magnetostrictive displacement sensors, displacement sensors, sensors, level gauges, connectors, and magnetic rings from the United States for consultation and selection!
MTS Systems is a company that develops magnetostrictive measurement technology. MTS magnetostrictive displacement sensors are suitable for extremely harsh working conditions such as high temperature, high pressure, and strong oscillation. Their output effectively solves the problem of power failure zeroing. Due to the non-contact and wear-resistant operation of sensitive components, the average time is 23 years.

In the paper and printing industry, MTS is commonly used in paper winding machines with upper and lower drums, installed on the upper drum oil cylinder to control the gap distance between the upper and lower drums and facilitate quick replacement of the drums. MTS is also widely used in fast paper winding machines, toilet paper cutting machines, and 8-color automatic fast printing machines.RHM0330MD631P102 American MTS Encoder*

Installation and Usage

Mechanical installation and use of rotary encoders:

There are various forms of mechanical installation for rotary encoders, including high-speed end installation, low-speed end installation, and auxiliary mechanical device installation.

High speed end installation: Installed on the shaft end (or gear connection) of the power motor. The advantages of this method areresolutionHigh, due to the presence of multi turn encoders4096Within this range, the number of rotations of the motor can be fully utilized to improve resolution. However, the disadvantage is that there may be gear clearance errors in the back and forth travel of moving objects after passing through the reduction gear. It is generally used for high-precision control positioning in one direction, such as steel rollingRoll gap controlIn addition, the encoder is directly installed at the high-speed end, and the motor vibration must be small, otherwise it is easy to damage the encoder.

Low speed end installation: Installed after the reduction gear, such as the shaft end of the winch wire rope drum or the shaft end of the last reduction gear section. This method has no gear backlash, and the measurement is more direct and accurate. This method generally measures long-distance positioning, such as variousupgrade equipmentPositioning of the feeding cart, etc.

Installation of auxiliary machinery:

Commonly used ones include gears and racks, chain belts, friction wheels, rope winding machinery, etc.

The materials of encoder encoders include glass, metal, and plastic. Glass encoders deposit very thin engraved lines on glass, which has good thermal stability and high accuracy. Metal encoders directly engrave lines with or without lines, which are not fragile. However, due to the thickness of metal, the accuracy is limited, and its thermal stability is one order of magnitude worse than that of glass. Plastic encoders are economical and have low cost, but their accuracy, thermal stability, and lifespan are all inferior.

resolution—Encoder with each rotation360The number of open or closed lines provided by a degree is called resolution, also known as resolution division, or directly referred to as how many lines, usually measured in increments per revolution5~10000Line.RHM0330MD631P102 American MTS Encoder*

MTSAttention to the selection of encoders

Three parameters should be noted:

1Mechanical installation dimensions: including positioning stop, shaft diameter, installation hole position;Cable outgoing method;Installation space volume;Whether the protection level of the working environment meets the requirements.

2Resolution: refers to the number of pulses output by the encoder per revolution during operation, and whether it meets the design accuracy requirements.

3Electrical interface: Encoder output methods commonly include push-pull output(FtypeHTLformat)Voltage output(E), open collector(C, CommonCforNPNType tube output,C2forPNPType tube output)Long line driver output. Its output mode should match the interface circuit of its control system.

MTSencoderpros and cons

MTSoptical encoder

Advantages:Small size, precision, high resolution, no contact or wear;The same variety can detect both angular displacement and linear displacement with the help of mechanical conversion devices;Multi loop photoelectric encoder can detect linear displacement of a considerable range(as25Multiple circles)Long lifespan, easy installation, diverse interface forms, and reasonable price. Mature technology has been widely applied both domestically and internationally for many years.

Disadvantages:Precise but with high protection requirements for outdoor and harsh environments; Measuring linear displacement requires the conversion of mechanical devices and the elimination of errors caused by mechanical clearances; Detecting objects in orbit is difficult to overcome slip.
