The two-wire system of IFM pressure sensors in Germany is relatively simple, and most customers know how to wire them. One wire is connected to the positive pole of the power supply, and the other wire, which is the signal wire, is connected to the negative pole of the power supply through the instrument. This is simple. The three wire system of pressure sensors adds a wire on the basis of the two-wire system, and this wire is directly connected to the negative pole of the power supply, which is a bit more complicated than the two-wire system. The four wire pressure sensor definitely has two power input terminals, and the other two are signal output terminals. Four wire systems are mostly voltage outputs rather than 4-20mA outputs. 4-20mA transmitters are called pressure transmitters, and most are made into two-wire systems. The signal output of some IFM pressure sensors in Germany is not amplified, with a full-scale output of only a few tens of millivolts, while some pressure sensors have amplification circuits inside, with a full-scale output of 0-2V. As for how to connect to the display instrument, it depends on the instrument's range. If there is a gear that is suitable for the output signal, it can be directly measured, otherwise a signal adjustment circuit needs to be added. The difference between five wire pressure sensors and four wire sensors is not significant, and there are relatively few five wire sensors on the market.

Correct installationNationwide free shipping sales of German IFM pressure sensors:
Usually, damage to high-temperature melt pressure sensors is caused by improper installation positions. If the sensor is forcibly installed in a small or irregularly shaped hole, it may cause damage to the sensor's diaphragm due to impact. Choosing a suitable tool to process the installation hole is beneficial for controlling the size of the installation hole. In addition, appropriate installation torque is beneficial for forming a good seal. However, if the installation torque is too high, it is easy to cause the high-temperature melt pressure sensor to slip off. To prevent this phenomenon, anti stripping compounds are usually applied to the threaded part of the sensor before installation.
1. Correct installation method for IFM pressure sensor in Germany:
(1) Verify the frequency response value of the pressure sensor under normal atmospheric pressure and standard temperature conditions using appropriate instruments.
(2) Verify the correctness of the coding of the pressure sensor and the corresponding frequency response signal.
2. Determine the specific installation location
In order to determine the number and specific installation location of the IFM pressure sensor in Germany, it is necessary to consider each inflation section of the inflation net.
(1) The pressure sensor must be installed along the cable, preferably at the cable joint.
(2) Each cable should be equipped with no less than 4 pressure sensors, and the two pressure sensors near the telephone office should be no more than 200m apart.
(3) Install one at the beginning and one at the end of each cable.
(4) Each cable should have one branch point installed. If two branch points are close together (less than 100 meters), only one can be installed.
(5) One cable should be installed at the location where the cable laying method (overhead, underground) changes
(6) For cables without branches, due to the consistent cable program of the base line, the installation spacing of pressure sensors should not be more than 500m, and the total number should not be less than 4.
(7) In order to facilitate the determination of the fault point of the pressure sensor, in addition to installing the pressure sensor at the starting point, an additional one needs to be installed at a distance of 150-200m from the starting point. Of course, in the design, economic and technical factors must be considered. If the pressure sensor does not need to be installed, it should not be installed.
