How to match Renault Koleo tire pressure sensor?

Koleos tire pressure sensors can be matched in the following ways:

1, the wiring of sensors has always been one of the most frequently asked questions in the process of customer purchase. Many customers don't know how to connect sensors. In fact, the wiring methods of various sensors are basically the same. Pressure sensors generally have two-wire, three-wire, four-wire and some five-wire systems.

2. The two-wire system of pressure sensor is relatively simple, and most customers know how to wire it. One wire is connected to the positive pole of the power supply, and the other wire, that is, the signal wire, is connected to the negative pole of the power supply through the instrument, which is the simplest. The three-wire system of pressure sensor is based on the two-wire system, which is directly connected to the negative electrode of power supply;

3, it is a little more troublesome than the two-wire system. The four-wire pressure sensor must have two power inputs and the other two signal outputs. Most of the four-wire system is voltage output instead of 4 ~ 20mA output. 4 ~ 20mA is called pressure transmitter, and most of them are made into two-wire system. Some signal outputs of the pressure sensor are not amplified;

4. The full-scale output is only tens of millivolts, while some pressure sensors have internal amplification circuits, and the full-scale output is 0 ~ 2V. As for how to connect the display instrument, it depends on the range of the instrument. If there is a gear suitable for output signal, it can be measured directly, otherwise, a signal adjustment circuit should be added. There is little difference between the five-wire pressure sensor and the four-wire pressure sensor, and there are few five-wire pressure sensors in the market.
