Mobile robots need to obtain information about surrounding obstacles in real time through sensors, including scale, shape, and orientation information, to complete obstacle avoidance. There are many kinds of sensors used in obstacle avoidance, and the common ones are vision sensors, laser sensors, infrared sensors, ultrasonic sensors, etc. ...

The prevailing understanding of sensors is to transmit sensory information to the machine, the same type of sensor, transmit different sensory information, we also know that the senses are the organs that sense external things to stimulate the machine, such as our eyes, stomping and nose for the machine, the sensor can realize all the sensory information, so many axes ...

Tension and compression sensors are one of the load cells. A device that converts physical data signals into accurately measured electronic signal outputs. It is widely used in industrial production weighing equipment, platform scales, electronic scales, hook scales, batching scales and other dynamometers. But different types of tension and compression sensors are used differently, and now ...

1. Temperature Excessive temperature is one of the common causes of differential pressure sensor failure, as there are many components of the differential pressure sensor that can only function properly within the specified temperature scale. During installation, if the sensor is exposed to temperatures beyond these temperature scales, it may be exposed to ...

1. Single-point load cells should be handled with care, especially for small capacity sensors with alloy aluminum as elastomers, any vibration-induced impact or drop is likely to cause large output errors. 2. Design loading ...

A device that converts the value of a force transducer into an associated electrical signal. Force is the direct cause of changes in the motion of materials. Force sensors can detect tension, tension, pressure, components, torque, internal stresses, and strains. The specific equipment is metal strain gauges, pressure sensors, etc., which have become electric ...

1. Avoid scum deposited in the catheter and contact the transmitter with corrosive or overheated media. 2. When measuring the gas pressure, the pressure port should be opened at the top of the process pipeline, and the transmitter should also be installed at the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process.

The air pressure sensor is a control sensor that can be operated according to the barometric pressure end sensing. Inside the air pressure sensor, an air intake tube is provided that can promise air ingress, and once the power is applied, air can be transferred to the inside of the sensor, and when air enters, squeeze sensing occurs ...

There are three goals of precision: precision, correctness, and precision. precision It sheds light on the sloppy nature of the measurement results. That is, for a certain stable goal (to be measured) by the same measurer ...

First, the first component blocking may be the wrong way of the device, the pressure point is unreasonable, so we often emphasize that the device must be the correct device, once the installation is wrong, maybe the installation is not good, it will bury endless hidden dangers for the back. What are the primary components? Orifice plates, remote transmission measuring joints, etc.

1. Shielding skills Containers are made from metal materials. Wrapping circuits that require maintenance between them can effectively prevent the disturbance of electric or magnetic fields, which is called shielding. Shielding can be divided into electrostatic shielding, electromagnetic shielding and low-frequency magnetic shielding. 2. Electrostatic shielding ...

An accelerometer is an electronic device that measures the force of acceleration and converts it into a signal. It is possible to calculate the skew angle of the device relative to the horizontal plane, and analyze the equipment movement method through the analysis of dynamic acceleration. The requirements for sensitivity are very high, in fact, no matter what type ...

1. Selection of reliability The potential of a sensor to persist in its properties over a period of time is called reliability. In addition to its own structure, the key factor affecting the long-term reliability of the controller is the use of harsh environments. Evil...

1) It is recommended to place the pressure sensor and its tee valve at the level of the axillary line, which is used for ventilation and sensor zeroing. 2) Approve the maintenance cap on the three-way valve to be perforated, connect the sensor with the monitor, and follow the instructions of the monitor to ...

The resistive sensor and the corresponding measuring circuit are composed of force, pressure, weighing, displacement, acceleration, torque and other measuring instruments for metallurgy, electric power, transportation, petrochemical, commercial, biomedical and national defense departments to carry out automatic weighing, process detection and realize the automation of the production process.

1. Static characteristics of the sensor The static characteristics of a sensor are related to the static input signal, the output and input of the sensor. Since the input and output are moment-independent at this point, the connection between them (i.e., the static properties of the sensor) can be used in an algebraic equation without time variables.

The working principle of the straight line is the same as that of the sliding rheostat, it is used as a voltage divider, it is the actual orientation of the measured direction with the relative output voltage. There are the following requirements for the operation of this equipment: 1 ...

1. How to estimate the standard detector body of photoelectric sensors? The thrift-beam type and the regressive reflection type are based on the diagonal length of the optical structure, and the scale of the opaque body with a large diameter is used as the standard object. The general through-beam type is based on the diagonal length of the projector and receiver as the standard detection ...

In order to select the best liquid level sensor, we need to understand not only the characteristics and conditions of the liquid to be measured, but also the advantages and limitations of different detection methods, and then we can select the most suitable sensor. Here are some of the most common inspection technologies on the market today. ...

1. Select the type of proximity switch according to the detected object. If the detection object is metal, the inductive proximity switch is preferred, and if the detection object is non-metal such as wood, plastic, paper, water, etc., or smaller and finer metals, the capacitive proximity switch should be selected. ...

1. The temperature and humidity sensor will drift during use, which is impossible to avoid. 2. The fundamental reason for the drift is that all pressure sensors are based on the elastic deformation of a kind of material, no matter how outstanding the elasticity of the raw material is, after each elastic recovery, there will always be ...
