Understanding the accuracy of sensors – ifm
There are three indicators of precision: precision, correctness, and precision, but how do you understand them?
precision
It sheds light on the sloppy nature of the measurement results. That is, for a certain stable target (to be measured) by the same measurer with the same sensor and measurement appearance in the appropriate ...

Precautions when switching the ifm on or off the power supply
The output status of the sensor when the power is turned on or off, whether it is detected or not, is OFF. In particular, when the power supply is turned on, the output condition is OFF for a certain period of time is called the initial reset. But in the following cases, the output will be momentarily ON(OFF) ...

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 ...

Classification of ifm temperature sensors
According to the measurement method, it can be divided into two categories: touch type and non-touch type.
1. Touch type
The detection part of the touch temperature sensor has an outstanding touch with the measured target, also known as a thermometer.
The thermometer reaches thermal equilibrium by conduction or convection, so that the thermometer indication ...

Diffuse photoelectric sensor target impact
1. The larger the object, the more light is reflected and the farther the sensing interval is.
2. For visible red light sensors, light colors can be detected at a greater scale than dark colors. The color of the target object has a much smaller effect on the infrared light sensor. Compared to a flat or matte appearance, a highly reflective ...

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 ...
