First, press the [Acknowledge] button to enter the first-level menu, press the [Up] or [Down] button to find the menu you want to set, and press the [Acknowledge] button to enter the set value, which will be displayed at this moment. Press and hold the [Up] or [Down] button, and when the value starts flashing, continue to press to adjust the value. Press the [Up] value to increase, and press the [Down] value to decrease; When the value to be set is reached, press the admit button to complete the parameter setting;
In most cases, the parameters that need to be set are the setpoint values, which are SP1 (setp point 1) and SP2 (channel 2).
Output channels 1 and 2 are both normally open contacts and can be set to normally closed or perhaps closed (OFF) as required.
Taking output channel 1 as an example, under the normally open output, if the measured value of the sensor is less than the set value SP1, the output channel 1 is activated, pin 4 will have a voltage output of 24V, and the LED light of 24V will be lit at the same time.
If the measured value of the sensor is greater than the set value SP1, the output channel 1 is closed, pin 4 does not output voltage, and the LED light 3 is off.
For example, if a moving object is 80 cm away from the sensor, the sensor laser will be emitted to the opposite side at a distance of 2.5 m when it detached. At this moment, if the value of SP1 can be set to 90cm, then the signal output of channel 1 will be in place after the object is in place, and the signal of channel 1 will be closed after it is detached. In this way, the output of channel 1 can be processed by connecting the output of channel 1 to the digital input of the PLC.

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 ...

The function and purpose of ifm pressure sensors
Pressure sensors are one of the more common sensors. Conventional pressure sensors are primarily mechanical devices, and the deformation of elastic parts indicates pressure. However, due to their size and weight, they are unable to generate electricity. The development of semiconductor skills has also led to the emergence of semiconductor pressure sensors.
