Industry Application

1.KTC is a versatile, suitable for various types of equipment to detect the position, such as: injection molding machines, die-casting machines, rubber injection machines, shoes, EVA injection machine, woodworking machine, hydraulic machine

2.KFT is a versatile slider linear displacement-free design, particularly adapted to reduce mechanical installation dimensions of length, suitable for application of larger stroke

3.KPZ is a mini Rod series, especially for the hole for space-constrained applications, and tie rod end with a 0.5mm of automatic features.

4.KPM is a mini articulated structure, suitable for small installations, an ontology cannot be fixed, moving swing position detection, neutral without any requirements for installation. Such as: Android, fetching machine, brick, ceramic machine, sluice

5.KTM is a mini Rod series, particularly suitable for space-constrained applications, such as: aircraft steering, steering, shoe machinery (the first machine after machine) thimbles position control of the injection molding machine, printing machinery, paper products and packaging machinery.

6.KTR is a self-recovery, is the minimum size of the miniaturization of structures, particularly suitable for small occasions, top putters do not need to install without having to

7.KPS is a miniature lever-style French installation structure, suitable for equipment and car applications within the cavity. Such as: coal, machinery, hydraulic machinery, and cavity detection

8.pulled rope displacement sensor application Yu warehouse location positioning, reservoir dam protection, gate open degrees control, pressure mechanical, paper mechanical, textile mechanical, metal plate mechanical, packaging mechanical, printing mechanical, level control instrument, building mechanical, industrial robot, shot out machine, woodworking mechanical, Elevator, empty pressure compressor/hydraulic machine, height machine, X-Y axis and the other length displacement, liquid bit, related size measurement and location control.

Common Problems and solutions:

1. insufficient power supply capacity Zhao-----electronic ruler shows fluctuations to provide a stable power supply capacity

2. FM interference and electrostatic disturbance----electronic device displays the number fluctuation signal lines and electric lines to separate on-line slot

3. display data regularly beat, or fail to display data----check that the line is broken or shorted

4. caused by poor installation will display digital watches----install need for neutral linear displacement sensor is very good, but parallelism can allow +-0.5MM errors, point can allow +-12 of error

5. sensor wiring error----correctly connect the power cord and output lines.

Technical knowledge

Electrical factors that affect the accuracy:

1. two-wire current output A2, maximum load, linear precision lower than minimum load 0.02%FS

2. three-wire current output type A3, maximum load, linear precision lower than minimum load 0.04%FS

3. voltage-output V1,V2 for empty, you need to load, load resistance cannot be less than 500kΩand precision than when you unloaded decreased 0.25%FS

4. resistance output type R-load type, you need to load, load resistance cannot be less than 500kΩ and accuracy than when you unloaded decreased 0.25%FS.

Precision Note:

1. when the callout parameter is a charged load test values, minimum load linear precision will raise about 0.02%FS

2. excessive load will cause the product does not work properly, or damage the product features

External mechanical bias effect on accuracy:

1. traction when the misalignment error S2=10002+102.S=1000.05mm. real traction lines with errors of the trip will be S=0.05mm

2. horizontal traction dangling error is: S2=1002+102,S=1000.05mm, the actual string error and trips will be 2S=0.1mm

3. traction side-wind effects error is S2=1002+202,S=1000.20mm, the actual string and trip error is 2S=0.40mm

Error rate: 0.02%FS

the corded foot is one of the biggest advantages of the installation of demand is not high, the linear precision less affected by external bias.

The advantages of two-wire current output type:

1. at present internationally as the standard displacement of the current remote sensing for analog signals.

2. susceptible to parasitic capacitance, resistance effect of pressure drop and temperature drift along, the transmission line is available very cheap and fine twisted-pair cable

3. the accuracy of the output signals are less prone to influence of load, the maximum and minimum load only linear precision 0.02%FS

4. output range, theoretically the transmission distance can be reached 1000m

5. transport terminal variable voltage signal into standard, versatility and applicability are well.
