The "PLC-BS3" has been designed to study the pressure measurement techniques and control application with a PLC. This unit is equipped with a pressure chamber with several sensors, with different uses and applications, adjusted to measure the pressure changes inside the chamber and control the pressure with a PLC. One of the pressure sensor output signals is conditioned to be connected to the PLC. The equipment works with a compressor and a manometer connected next to a regulating valve that can adjust the maximum pressure inside the chamber. On both sides of the pressure chamber there are two diaphragms where displacement sensors are connected to measure the pressure valve. The pressure inside the chamber can be controlled by a PLC, controlling the air supply depending on the pressure values obtained from a sensor.
* Available PLC models of different manufacturers: PANASONIC, SIEMENS, OMRON, MITSUBISHI, ALLEN BRADLEY, etc.
