World Class Expert in Special Angle Displacement Sensor Technology
Resolver
A rotary transformer is an electromagnetic sensor, also known as a synchronous decomposer, used to measure the axial displacement and angular velocity of a rotating object. It consists of a stator and a rotor.
Magnetic resistance resolver
A sensor that uses the change of air gap magnetic resistance to output signals, with wide temperature range, high protection level, simple structure, high reliability, flexible size, low cost, and ultra-thin design.
Brushless Rotary Transformer
With contactless electromagnetic induction principle, wide temperature, high protection level, output absolute angle and high precision.
Multipole/Dual Channel Rotary Transformer
With electromagnetic induction principle, non-contact, wide temperature, output absolute angle, angular second level ultra-high precision and high value can also be designed.
RVDT Angular Displacement Sensor
It is an abbreviation of rotary variable differential transformer, belonging to angular displacement sensor. In other words, the rotation of the mechanical component is transmitted to the shaft of the angular displacement sensor to drive the connected spoiler/iron core, change the induced voltage/inductance in the coil and output the voltage/current signal proportional to the rotation angle.
Dual Redundancy RVDT
RVDT non-contact design for unlimited resolution and long life.
Single Redundancy RVDT
High accuracy for 360 ° rotation measurement.
Hollow Shaft RVDT
It is used for transmission and feedback control of ball valve position, hydraulic pump, forklift, robot, fan and other equipment.
LVDT Wire Displacement Sensor
It is the abbreviation of linear variable differential transformer and belongs to linear displacement sensor. The working principle is the iron core movable transformer, which is composed of one primary coil, two secondary coils, iron core, coil frame, shell, etc.
Dual Redundancy LVDT
Friction-free measurement, infinite mechanical life, infinite resolution.
Single Redundancy LVDT
Zero Position Repeatability, Axial Restraint, Rugged, Environmentally Resilient, I/O Isolation.
Single Redundancy LVDT
Applied in aerospace, machinery, construction, textile, railway, coal, metallurgy, plastics, chemical industry and scientific research institutions and other industries of the national economy.
Magnetic Sensitive Encoder
An electronic device that uses changes in the magnetic field to accurately measure the rotational angle or angular displacement of an object.
CJWDC15A
The sensor element (magnetically sensitive chip) has no contact with the magnet before and is suitable for long life and high reliability applications.
CJWDC15
It replaces traditional potentiometers in many fields such as automobile, industry and consumer electronics.
Eddy Current Sensor
Eddy current sensor excites metal rotor to generate eddy current through high-frequency magnetic field (2-5MHz), receives coil to detect magnetic field change and outputs orthogonal signal, and calculates angle after demodulation. The sensor is composed of eddy current rotor, exciting coil, receiving coil, eddy current control module and printed circuit board assembly.
Type 59
Potting glue sealing design, applicable to oil-cooled/water-cooled electric drive system, anti-EMC interference.
Type 101
The angle accuracy can reach ± 22.5 ′ mech (4 pairs of poles), which is superior to ± 33 ′ mech of traditional rotary transformer.
Type 141
High frequency magnetic field (2~5MHz) with fast response, suitable for motor detection up to 150000 RPM.
Frameless Torque Motor
It is a new power unit that breaks through the limitation of traditional motor structure. The core feature is that the external frame and bearing are omitted, and only the rotor and stator are retained.
