Hello: The angle sensor can be applied to different industries and different fields, the general industrial control requirements: power supply (24V), output signal, general application, and the communication distance is not very far, and the angle measurement is very standardized, no need to measure special angles, you can choose an analog output angle sensor (RB100LA-3006-24VV10-IP67), this sensor is 24V power supply, 0-360 ° corresponding to 0-10V standard linearity.

When you have high requirements for the signal output of the measurement, you can choose the angle sensor of 4-20mA, relative to the voltage, the signal stability of the angle sensor of the current type is more reliable, and the communication of the angle sensor of digital communication is also divided into many kinds, the commonly used TTL (suitable for the integrated development of single-chip microcomputer), 232 (suitable for the secondary development of the host computer), 485 (suitable for the development of control equipment), different communication interface levels are used in different environments, You can choose according to your needs.

See what kind of output you want? XYK-BMJ-38Z6-V This is more commonly used, and it is not expensive.

1. There are two types of angle sensors. From the perspective of construction form, angle sensors can be divided into two categories: wirewound angle sensors and non-wirewound angle sensors.

2. The wire lead selling angle sensor is to wind the resistance wire on the metal, ceramic and plastic skeleton of plum branch as a resistance element. Advantages: low temperature coefficient of resistance, good stability of electro-sensitive resistance, large power load, long working life.

Disadvantages: the resolution has a certain step, the total resistance range is narrow, and the high-frequency performance is poor.

3. Non-wirewound angle sensors include synthetic film angle sensors, glass glaze angle sensors, conductive plastic angle sensors, etc.

An angle sensor, literally, may be nothing more than an instrument for measuring angles, but it's not as simple as you might think. It is very versatile, and it can be said that it is as ubiquitous as firewood, rice, oil, and salt in our lives. The angle sensor can measure 360 ° without dead angles, but the so-called industry has a specialization, the angle sensor has a wide range of applications, and the models of the sensor are also diversified, so let's learn how to choose the angle sensor model together.

Model: SCA610-CA1H1G

The inclination angle sensor is used in high-precision laser instrument leveling, construction machinery and equipment leveling, long-distance ranging instrument, high-altitude platform safety protection, pitch angle measurement of directional satellite communication antenna, ship navigation attitude measurement, shield pipe jacking application, dam detection, geological equipment inclination monitoring, artillery barrel initial firing angle measurement, radar vehicle platform detection, satellite communication vehicle attitude detection, etc.

Model: WYT-1, WYT-3, WHY-3, WYT-250

The non-contact angle sensor converts the mechanical rotation into an electrical signal and the angle of rotation is measured without an electrical contact. Compared with wirewound, metal film or conductive plastic potentiometers, this sensor has the following characteristics: no contact, high sensitivity, extremely long life, no noise, high repeatability, monotonic infinite resolution, no wear, high reliability, high frequency response characteristics, low torque, 360° continuous rotation, and resistance to humid environments.

WYT-1 angle sensor, small size, light weight, widely used in aviation, medical equipment, military, electronics, textile, shipbuilding and other industries of angle control, valve control, tension control, robots and other precision instrumentation, to meet the requirements of frequent mechanical changes and long service life in the workplace. Realize the function of automatically measuring the angle and controlling the position.

Model: DWQT-BZ-V

The magnetic sensing angle sensor adopts high-performance integrated magnetic sensing components, uses the characteristics of magnetic signal sensing non-contact, and cooperates with micro-computer for intelligent signal processing to make a new generation of 360° full-scale and programmable selected measurement interval angle sensor. The sensor has the outstanding advantages of high resolution, good temperature stability, etc., and has excellent cost performance. It has strong environmental applicability and can be used in harsh industrial environments such as water, oil, steam, dust, high and low temperature, vibration and impact.

The above types of angle sensors are more commonly used, and they are also the types we see more. There is still a lot of knowledge about angle sensors, and we have only made a preliminary understanding of its model. But this knowledge is also very practical, in life, we can choose which model of angle sensor is more suitable according to its characteristics and functions, use different sensors from time to place, and make full use of its advantages to provide convenience for our lives.

Angle sensors are widely used in practical operation and can be applied to the needs of different industries and different fields and environments. However, in order to reduce the occurrence of errors in the measurement process, it is necessary to choose the best angle sensor. Especially for novices, how to judge the quality of angle sensors?

1. Selection of sensitivity.

In general, within the linear range of an angle sensor, the higher the sensitivity of the angle sensor, the better. This is because only when the sensitivity is high, the value of the output signal corresponding to the change to be measured is relatively large, which is conducive to signal processing. However, it should be noted that the sensitivity of the sensor is high, and the external noise that is not related to the measurement is also easy to mix, and will also be amplified by the amplification system, affecting the measurement accuracy.

Therefore, it is required that the sensor itself should have a high signal-to-noise ratio to minimize the factory disturbance signal introduced from the outside world.

The sensitivity of the sensor is directional. When the measured quantity is a single vector and its directionality is required to be high, the sensor with low sensitivity in other directions should be selected; If the measurement is a multi-dimensional vector, the smaller the cross-sensitivity of the sensor, the better.

2. Frequency response characteristics.

The frequency response characteristics of the angle sensor determine the frequency range to be measured, and the measurement conditions must be maintained without distortion within the allowable frequency range, in fact, there is always a certain delay in the response of the sensor, and the shorter the delay time, the better.

The frequency response of the sensor is high, and the frequency range of the measurable signal is wide, while due to the influence of structural characteristics, the inertia of the mechanical system is larger, and the frequency of the measurable signal is lower because of the low frequency of the sensor.

In dynamic measurements, the response characteristics should be based on the characteristics of the signal (steady-state, transient, random, etc.) to avoid over-fire errors.

3. Linear range.

The linear range of an angle sensor refers to the range in which the output is proportional to the input. Theoretically, the sensitivity remains constant within this range. The wider the linear range of the sensor, the greater the measuring range and the measurement accuracy.

When selecting a sensor, when the type of sensor is determined, the first thing to see is whether its range meets the requirements.

But in reality, no sensor can guarantee absolute linearity, and its linearity is also relative. When the required measurement accuracy is relatively low, within a certain range, the sensor with small nonlinear error can be approximately regarded as linear, which will bring great convenience to the measurement.

4. Stability.

The ability of a sensor to remain unchanged after a period of use is called stability. In addition to the structure of the sensor itself, the factors that affect the long-term stability of the sensor are mainly the environment in which the sensor is used. Therefore, in order for the sensor to have good stability, the sensor must have strong environmental adaptability.

In addition, before selecting an angle sensor, it is necessary to investigate the environment in which it will be used, and select the appropriate sensor according to the specific environment in which it will be used, or take appropriate measures to reduce the impact of the environment.
