	Fiber optic sensor selection points – ifm 1. Determine the type according to the measurement object and environment It is necessary to carefully analyze the measurement operation and consider which principle of sensor to use for measurement, because even if the same physical quantity is measured, it can be achieved by different principles. Secondly, we have to consider the range, volume (whether the space is satisfied), amperemia ...
	Sensor installation requirements and precautions – ifm sensors 1. Device requirements: 1. Measure the shaft diameter and center height of the high-precision displacement sensor. 2.

The sensation is more ...
	Load cell wiring method – ifm There are four-wire and six-wire load cells. Four-wire system: EXC EXC: Power cord, that is, the DC power supply supplied by the instrument to the sensor. SIG, SIG-: The signal line, that is, the signal line output by the sensor, is output to the instrument. In addition to the above four lines, there are more than two in the four-wire system: SEN, SEN-: feedback line ...
	Use and maintenance of strain gauge load cells – ifm The aluminum foil sensor is composed of elastomer, strain gauge, adhesive, maintenance layer, compensation circuit, etc. The strain transmission path is: elastomer - + adhesive → strain gauge sensitive grid - + overlay - maintenance coating, which constitutes a complex system that is more different from the strain gauge itself. If the application attached to the elastomer ...
	Choice of load cell construction form – ifm First, the application environment of the weighing system Sensors operating in high-temperature environments should use high-temperature resistant sensors, and especially harsh occasions must also be equipped with heat-insulation, water-cooled or air-cooled devices. For use in alpine areas, load cells with heating devices should be considered. ...
	Precautions for the use of sensors and installation requirements - ifm Precautions for using sensors: 1) The sensor should not be installed in the following places: direct sunlight, high temperature, frost, and corrosive gas. 2) Do not use the same wiring pipe or wiring groove as the power line and power line to connect the wire.
	Range, accuracy and installation of load cells – ifm 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.
	Moisture-proof method for sensors – ifm As an accurate detection device, if the sensor is damp, it will be troublesome, the sensor will affect its accuracy and stability when it is damp, and it will form a problem if the sensor is used in a more important place, then the loss of the formation is very heavy. In '08 there was a ...
	Zero drift of pressure sensors – ifm Zero drift is an important indicator that affects the function of the pressure sensor, so when the problem occurs, we should pay attention to it, so what is zero drift? Zero drift refers to when the input signal of the expansion circuit is zero, due to the influence of temperature changes, power supply voltage instability and other factors, so that ...
	The solution to the non-output of pressure transmitters – ifm 1. If the pressure transmitter is used in cooperation with the digital display, if the digital display does not appear at this time, then the user may say that the pressure transmitter has no output, but in fact, this problem is obvious, and it is unreasonable to hastily determine that the pressure transmitter has no output. If the pressure transmitter is working properly, ...
	The criterion for judging vibration sensors – ifm 1. The size of the measured oscillation; 2. The frequency scale of the oscillating signal; 3. The environment of the oscillation test site; 1) Selection and measurement scale of the sensitivity of the oscillation sensor Estimating the amount of oscillation will help ...
	Pressure sensor encounters fault handling method – ifm Don't panic when you encounter a problem with the pressure sensor, you should find a way to solve it, if the pressure rises, the transmitter output will not rise. In this case, first look at the pressure sensor pressure interface to see if it is leaking or blocked; If not, check the connection form and power supply; If...
	Introduction to sensor design tips – ifm 1. Start with the bus east and west As a first step, the engineer should take the approach of first interfacing the sensor, which is through a bus stuff to constrain the ignorance. A bus thing connects to a personal computer (PC) and then to the sensor for I2C, SPI or other ...
	Features of the S-type load cell – ifm 1. S-type load cells are moderately priced and suitable for mass production - good sensor consistency is required, suitable for automated batch production, and high requirements for processing equipment to eliminate inconsistencies and faults formed by manual operation. 2、 ...
	Accuracy adjustment of inclination sensors – ifm The first step is the ambient temperature, what is the normal temperature? 25±15°C, if there is a regular measurement temperature of the measured specimen, then the regular temperature shall prevail; The second step, the condition of the product, that is, the normal operating condition, ...
	Selection of sensor sensitivity and range – ifm The sensitivity of the sensor is one of the most basic goals of the sensor. The sensitivity of the sensor directly affects the measurement of the oscillation signal. It is not difficult to understand that the sensitivity of the sensor should be determined according to the size of the oscillation (acceleration value) to be measured, but since piezoelectric acceleration is a measurement of the acceleration value of the oscillation, ...
	Common faults of lambda sensors – ifm 1. Oxygen sensor poisoning. Oxygen sensor poisoning is a common and difficult problem to prevent, especially in cars that often use leaded gasoline, and even new oxygen sensors can only operate for a few thousand kilometers. If it's just a subtle case of lead poisoning, then use a box of lead-free ...
	Common faults of pressure sensors – ifm If the power supply is normal, it is necessary to carry out a simple pressurization to see if the output has changed, perhaps observe whether the zero position of the sensor has an output, assuming that it has not changed, the sensor has been damaged, otherwise it is the appearance of the damage or other links of the whole system. ...
	Common faults in eddy-current sensors – ifm The eddy-current displacement sensor is a commonly used measuring instrument, which can accurately measure the static and dynamic relative displacement changes between the measured body (if necessary, a metal conductor) and the end face of the probe, and has the advantages of flexible use, stable function, high reliability and simple protection. ...
	The difference between fiber optic sensors and photoelectric sensors – ifm 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. ...
	The main classification of current sensors is ifm (1) Resistance shunt: It is actually a resistance with a very small resistance value, when there is a current passage period, according to Ohm's law, the voltage occurs in the resistance, and the current size is known according to the measured voltage value. The resistance shunt has high precision, fast response, low cost, simple use, and disadvantages ...
