	Sensors, temperature sensors, RTDs and thermocouples – ifm RTDs and thermocouples are the most commonly used temperature sensing elements for temperature sensors. The operating principle of thermocouple temperature sensor is that the two ends of the contact surface of two kinds of incompatible metals produce a weak and weak voltage when the temperature is inconsistent, and the temperature is measured by expanding the electric, which is not necessary to measure the high temperature. RTD Temperature Sensors ...

The use includes current sensors, angle sensors, gear sensors, and space environment measurement. 2、 ...
	Precautions for the selection of level transmitters – ifm The differential pressure transmitter is a transmitter that measures the pressure difference between the two ends of the transmitter, and outputs a standard signal (such as 4-20mA, 1-5V). The difference between the differential pressure transmitter and the general pressure transmitter is that they have 2 pressure interfaces, and the differential pressure transmitter is generally divided into positive pressure end and negative pressure end.
	Correct use of the high-temperature pressure sensor method – ifm 1. It is necessary for the sensor to be properly installed Damage to high-temperature pressure sensors is usually caused by their installation in improperly machined holes. When the sensor is loaded into a hole that is too small or eccentric, the sensor diaphragm may be damaged, which can then cause the instrument to not function properly. Can...
	High-frequency pressure sensor output signal – ifm The conversion of the pressure to the electrical signal is done by the physical deformation of the strain gauge, and the strain gauge is bonded to the diaphragm of the pressure sensor and wired into a Wheatstone bridge structure. The pressure exerted on a high-frequency pressure sensor causes the diaphragm to flex, which causes the strain gauge to strain. Strain will occur ...
	Fuel level sensors monitor the cause of the fuel level – ifm The oil level sensor according to the resistance is mechanically connected to the float, and the float can rise or fall with the fuel level, and the resistance of the sensor changes as the float moves. The sensor used is part of the current balance circuit in the fuel gauge display circuit, which is generally used to drive ...
	What are the typical designs of torque sensors – 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...
	Load cell range and accuracy – ifm 1. Sensor scale: 1) Normal use (static experiment or quasi-static experiment, when the frequency of application is not high, the scale of the sensor should be selected to consider the measured force value, as well as the component of the auxiliary tool (test fixture), etc.). 2) When used dynamically, the scale of the sensor is generally larger than the ...
	The difference between a sensor module and a sensor – ifm The first statement is that the sensor module belongs to a kind of sensor module, according to different packaging forms, the sensor module can be divided into different types such as chip BQ4010YMA-200, PCBA, shell packaging module, etc., collectively referred to as the sensor module, different types of sensor modules according to different ...
	The cause of sensor interference – ifm 1. The PCB layout board touches the problem, and when the imitation signal is traced, the imitation signal is not wrapped with imitation, and there is even a possibility that the signal line is directly taken to the power line, which is easy to receive disturbance. Solution: When it is a board, wrap the GND to imitate the signal line. If there is a model ...
	Pressure sensor interference source – ifm We often use pressure sensors, there are pressure sensors in various environments, sometimes we will find that the pressure sensor in the use of time and time measurement is not accurate, or the signal output is unstable, which is generally disturbed by the disturbance source, the disturbance source of the pressure sensor mainly includes...
	Notes on Linear Position Sensors – ifm Whether it is a linear displacement sensor or a rope displacement sensor, it often encounters a variety of problems when it is used, including quality problems, application problems, environmental problems, etc., but the use of problems is common, and improper use simply makes the sensor damaged. So what we're using ...
	How sensor detection avoids interference – ifm Sensor detection is known to prevent disturbances. Once disturbed, the sensor may be damaged, the measurement system will be affected, the inaccurate data will affect the future use, the judgment will be biased, and the impact can be large or small, so anti-interference is very important. Today we're going to comment ...
	Analysis of sensor technical indicators - ifm 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...
	Method for measuring torque using angle sensors – ifm It is difficult to measure torque on a rolling shaft, and there are several ways to do it. The most common method is to derive the torque from the energy required by the rolling shaft. In general, this means measuring the current of the motor that drives the rolling shaft. This is sketchy but inaccurate, as ...
	Correct installation of pressure sensors – ifm Generally, the damage of the high-temperature melt pressure sensor is caused by the improper orientation of the device, if the sensor is forcibly installed in a hole that is too small or an irregularly shaped hole, it may cause the vibration film of the sensor to be damaged by impact, choose the appropriate thing to process the device hole, ...
	Failure analysis of the ifm pressure sensor PN2071 1. ifm sensor PN2071 pressure up, sensor output can not go up in this case, first should check whether the pressure interface is leaking or blocked, if you admit that it is not, check the wiring method and check the power supply, if the power supply is normal, then simply pressurize to see if the output changes, maybe observe ...
	Sensors in the mass flow controller – ifm The mass flow manipulator is a new type of flow measurement and monitoring instrument, as well as an instrument that can conveniently monitor the activity of different gases in the pipeline without temperature and pressure compensation. Its working principle is to send the flow signal measured by the heating bridge of the sensor to the amplifier for amplification, and the enlarged ...
	Structure and application of resistive sensors - ifm Structure of a resistive sensor The structure of a resistive sensor consists of two basic parts: a resistive element and a brush (movable contact). The motion of the brushes in relation to the resistive elements can be linear, rotational and spiral, thus converting the linear or angular displacement into the necessary ...
