Hi experts. I would like to ask some question. Can I connect three wire pressure sensor atlas copco 1089 0575 51 (ecactly is a pressure transducer) to Logo 0-10V Analog input, This transucer operate at 0,5-4,5V range. It have wires: Signal, GND and V+ I try to connect this in different ways, but the value never increase with the pressure that I see on the analog manometer

What is the range of the sensor? For which logo? |

The sensor range is 0-10 bar and logo is 6ed1052-1md00-0ba6 |

Yuo have to make some calculations. The sensor = 0,5 V to 4,5 Volt, and your LOGO works 0 - 10 Volt. Range 0,5V to 4,5 Volt = 4 Volt 0-10 Bar. If the sensor works with a range of 10 Volt, the sensor must be 10/4x10= 25Bar The sensor starts at 0,5 Volt (not at 0 Volt) 0,5 Volt in a range of 25 Bar = 1,25 Bar. So the offset must be - 1,25 bar The end range of the sensor is 25 Bar (Range) - 1,25 Bar (Offset) = 23,75 Bar So are the settings of the analog amplifier block.

Here's another solution proposed by me. Attachmentpressure_0-10_bar.zip (472 Downloads) |

Thank You experts. This is my solution for this machine and probably for the most of air compressor. The Q1 and Q2 outputs are responsible for star-delta motor start. The Q4 output is responsible for load/unload valve The Q3 output is the stop function. AI2 is for PT1000 temperature sensor Will be greate, if someone want or can improve this.
