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 distribution pipe or wiring groove as the power line and power line for the connecting wire, or use the shielded wire.
3) The connecting wire should not be too thin and the length should not be too long.
4) After the power is turned on, wait for a certain moment before testing.
Sensor device process requirements:
The sensor device method is correct, and the position or sensitivity of the sensor should be adjusted after the device is completed, so that the sensor can accurately detect the corresponding signal.
Device process requirements for circuits:
1) The connecting wire is selected correctly.
2) The connection points of each connection point of the circuit are reliable and firm, and the longest exposed copper wire cannot exceed 2mm.
3) The wires entering the wiring block should be numbered, and the number tube should be covered.
4) There can be no more than 2 connecting wires for the same terminal block.
Safety requirements for plant operation:
In the process of assembly, it is necessary to achieve the "top of the safety list", please read the following requirements carefully.
1) It is necessary to correctly use a word or a cross screwdriver, needle-nose pliers, and wire strippers to prevent the screwdriver or pliers from hurting hands during operation;
2) After the device is finished, confirm that the wiring is correct, and then send power for testing;
3) Disassembly and assembly should be carried out in a state of power failure;
4) When using the surface live measurement, it must be carried out in accordance with the safety regulations of the appearance use;
5) When the device is installed, it is not necessary to knock on the device device to prevent damage to the device.

Differential pressure sensor function – ifm sensors
A differential pressure sensor is a sensor used to measure the difference between two pressures, usually used to measure the pressure difference between the front and rear ends of a device or component.
A typical application of differential pressure sensors is to measure the difference in exhaust pressure between the front and rear channels of the exhaust particulate trap of a passenger car engine.

Precautions for the installation of ultrasonic level gauges
1. The appearance is installed outdoors, and it is recommended to install a sunshade to prolong the service life of the appearance.
2. Wire and cable protection pipes should be sealed to avoid water accumulation.
3. Although the appearance itself is equipped with lightning protection equipment, when the appearance is used in the multi-lightning area, it is advocated to distinguish the inlet and outlet lines on the surface.
