Wireless sensor problems and solutions – ifm

Unlike load cells or force transducers, the measuring body of a torque transducer is not subjected to a tension load when used, but is torsionally affected by lever torque or torque. Therefore, torque sensors require special strain gauges to measure this type of load, i.e. torque. Canon...

Temperature sensor 1. The sensor should be firmly grounded, and the wire side of the sensor should not be short-circuited. 2. The thermistor of the moving magnet water thermometer sensor will increase with the temperature and the resistance value will decrease. Fuel level sensor ...

Photoelectric switch (photoelectric sensor) is the abbreviation of photoelectric proximity switch, which uses the shielding or reflection of the beam by the detected object to connect the circuit by the synchronous loop to detect the presence or absence of the object. When the photoelectric sensor outputs the signal, the signal is occasionally unstable, and many people do not know what to do.

1. Device requirements: 1. Measure the shaft diameter and center height of the high-precision displacement sensor. 2. Two sets of couplings are used to connect the device with high-precision displacement sensor between the power source and the load. 3. The sensor can be connected with a rigid or elastic coupling. The sensation is more ...

1. Encoder own problem: It refers to the problem of the encoder's own components, resulting in its inability to generate and output correct waveforms. In this case, the encoder needs to be replaced or its internal components repaired. 2. Encoder connection cable problem: the probability of this problem is high, and the maintenance is under repair.

Spindle speed detection In order to prevent damage to wind turbines due to overspeeding, the rotational speed is detected using inductive sensors and evaluated by safety-related speed monitors. ifm IFS24X series inductive sensors with M12 ...

Diagnose sensor faults based on mathematical models? When there is a problem, the first time is to diagnose it, see where the problem is, so that it is easy to deal with, from different angles, we use more than one method when diagnosing the problem, if this is classified, it can be divided into two ...

1. High degree of activity; 2. A few shapes have multi-faceted adaptability, and can be made into arbitrary shape of optical fiber sensors; 3. It can manufacture devices that sense various physical information (sound, magnetism, temperature, rotation, etc.); 4. It can be used for high voltage, electrical noise, ...

1. According to the measurement object and measurement environment In order to carry out a specific measurement operation, it is necessary to consider the principle of the sensor first, which requires an analysis of many factors. Since, even for the measurement of the same physical quantity, there are sensors with multiple principles to choose from.

The first step in selecting a pressure sensor is to determine the pressure to be measured. Exciter sensors are divided into mechanical pressure and pneumatic pressure (hydraulic). The mechanical pressure unit is generally N.KN.KGF, etc. The pneumatic and hydraulic units are generally KPA, MPa, PSI, etc. This article describes the selection of mechanical pressures. ...

Optical fiber sensors and photoelectric sensors are two typical sensors, which are widely used in production and measurement, so what is the difference between the two? Next, we will analyze the differences between the two from the perspective of principle and use. ...

Because of the many technical goals of sensors, various data and literature have different perspectives, so that different people have different understandings, and even misunderstandings and ambiguities. To this end, the following are some of the top technical objectives of sensors: 1. Resolving power and resolution: Definition...

For more than 30 years, ifm is a global group of companies that researches, manufactures and sells components and systems for the detection, control and processing of signals – from standard sensors to application-specific controllers. ...

Torque sensor is a component that must be installed in some industrial products, mainly used to measure speed and viewpoint orientation, but different types of sensors have different ways to use and function, what is the classification of torque sensor? Resistance strain ...

The laser sensor consists of a laser, a laser detector and a measuring circuit. The laser sensor is a new type of measuring instrument, and its advantages are that it can complete the remote interval measurement without touch, with fast speed, high precision, large measuring range, strong anti-light and electric disturbance ability, etc. When the laser sensor is operating, the laser is first ...

With the continuous development of large-scale biogas digester construction and comprehensive utilization of biogas, biogas power generation has "presented"! It is a comprehensive utilization technology of power integrating environmental protection and energy saving, which not only deals with the environmental problems in the biogas project, consumes a lot of waste, protects the environment, and reduces greenhouse gas.

1. Inspection interval Detect the stop, start and orientation of elevators and lifting equipment; Detect the orientation of the vehicle to prevent two objects from colliding; Detect the setting orientation of the operating machinery and the limit orientation of the moving machine or components; Detect the abort azimuth of the rotary body, the opening or closing of the valve; Detection of pneumatic or hydraulic cylinders ...

1. The scale of the sensor: (1) In normal use (static test or quasi-static test, the frequency of use is not high), the scale of the sensor should be selected to consider the force value of the measurement, but also consider the weight of the auxiliary tool (test fixture) and so on.

Wiring method The wiring method of various sensors is basically the same, and the pressure sensor generally has a two-wire system, a three-wire system, a four-wire system, and some five-wire systems. The two-wire system of the pressure sensor is relatively simple, and one wire ...

The decentralised AS-i IO-Link master module acts as a gateway between the intelligent IO-Link sensor and the AS-Interface fieldbus. They combine the advantages of the AS-i cabling system with standard IO-Link communication. With IO-Link, connected sensors or actuators can be detailed ...
