World Class Expert in Special Angle Displacement Sensor Technology
Resolver
The rotary transformer is an electromagnetic sensor, also known as a synchronous decomposer. It is used to measure the rotational shaft angle displacement and angular velocity of rotating objects, and is composed of a stator and a rotor.
Magnetic Resistance Resolver
A sensor that outputs signals by utilizing the change in air-gap magnetic resistance. It features wide temperature range, high protection level, simple structure, high reliability, flexible size, low cost and ultra-thin design.
Brushless Resolver
Utilizing the principle of non-contact electromagnetic induction, it features wide temperature range, high protection level, the ability to output absolute angles, and high precision.
Multi-pole/Dual-Channel Resolver
By utilizing the principle of electromagnetic induction, it is also possible to design a non-contact, wide-temperature, capable of outputting absolute angles, with ultra-high precision at the level of arc seconds, and of high value.
RVDT Angular Displacement Sensor
It is the abbreviation of Rotating Variable Differential Transformer and belongs to an angular displacement sensor. That is, the rotation of the mechanical component is transmitted to the shaft of the angular displacement sensor, driving the attached guide plate/iron core, which changes the induced voltage/inductance in the coil, and outputs a voltage/current signal proportional to the rotation angle.
Dual-Redundancy RVDT
RVDT adopts a non-contact design, featuring infinite resolution and long service life.
Single-Redundancy RVDT
The feature of high precision enables 360° rotational measurement.
Hollow Shaft RVDT
It is widely applied in the transmission and feedback control of equipment such as ball valves, hydraulic pumps, forklifts, robots, and fans.
LVDT Linear Displacement Sensor
It is the abbreviation of Linear Variable Differential Transformer and belongs to a linear displacement sensor. The working principle is an electromechanical transformer with a movable core. It is composed of a primary coil, two secondary coils, a core, a coil frame, an outer shell and other components.
Dual-Redundancy LVDT
No friction measurement, unlimited mechanical lifespan, unlimited resolution.
Single-Redundancy LVDT
Zero position repeatability, axial suppression, sturdy and durable, strong environmental adaptability, input/output isolation
Single Redundancy LVDT
It is widely applied in various sectors of the national economy, including aerospace, machinery, construction, textiles, railways, coal, metallurgy, plastics, chemicals, as well as research institutions and universities.
Magnetic Sensor Encoder
An electronic device that precisely measures the rotation angle or angular displacement of an object by utilizing changes in magnetic fields.
CJWDC15A
The sensor element (magnetic sensitive chip) has no contact with the magnet, making it suitable for applications requiring long lifespan and high reliability.
CJWDC15
It has replaced the traditional potentiometer in numerous fields such as automobiles, industry, and consumer electronics.
Eddy Current Sensor
The eddy current sensor generates eddy currents in the metal rotor by exciting it with a high-frequency magnetic field (2-5 MHz). The receiving coil detects the changes in the magnetic field and outputs orthogonal signals. After demodulation, the angle can be calculated. The sensor is composed of an eddy current rotor, an excitation coil, a receiving coil, an eddy current control module and a printed circuit board component.
Type 59
Sealing adhesive sealing design, suitable for oil-cooled / water-cooled electric drive systems, with anti-EMC interference capability
Type 101
The angle accuracy can reach ±22.5' mech (4 pairs of poles), which is superior to the ±33'mech of traditional rotary transformers.
Type 141
High-frequency magnetic fields (2 - 5 MHz) have a fast response speed and are suitable for detecting motors with a maximum speed of 150,000 RPM.
Frameless Torque Motor
It is a new type of power device that breaks through the limitations of traditional motor structures. Its core feature is that it omits the external frame and bearings, and only retains the rotor and stator components.
