PRESSURE CONTROL DEVICE

A pressure control device for controlling a compressor includes a pressure sensor configured to measure pressure of a pressure line and a processing circuit. The processing circuit is configured to receive the measured pressure of the pressure line from the pressure sensor and control the compressor based on a set-point and the measured pressure. The pressure control device includes a mechanical switch sensitive to the pressure of the pressure line and configured to move between an open position and a closed position responsive to the pressure of the pressure line. Movement of the mechanical switch into one of the open position or the closed position causes the compressor to turn off and overrides the control of the compressor by the processing circuit. 种用于控制压缩机的压力控制装置包括压力传感器和处理电路，所述压力传感器被配置用于测量压力线的压力。所述处理电路被配置用于从所述压力传感器接收所述压力线的所测量压力并且基于设定值和所述所测量压力来控制所述压缩机。所述压力控制装置包括机械开关，所述机械开关对所述压力线的所述压力敏感并且被配置用于响应于所述压力线的所述压力而在断开位置与闭合位置之间移动。所述机械开关移动至所述断开位置或所述闭合位置之使得所述压缩机关断，并且超控所述处理电路对所述压缩机的所述控制。
