Differential pressure switch is the use of two pipelines in general to issue a number of telecommunications differential pressure switch, when the series ends of tubing pressure increased (or decreased) exceeds the setpoint pressure switch controller 609, issue signals to control or monitor the reversing valve lubrication system. Open the valve and then the big (or off small) sor pressure switch, so the system ends of the tube pressure decreases to normal operation of the system. AFS930.8x series of air pressure switch also called gas pressure switch, which can be used to monitor air or other non-flammable and non-corrosive other overpressure, vacuum and differential pressure switch _ dwyer pressure switch _ Li gifted Litas electromechanical provided by Changzhou gifted Litas Electrical Co., Ltd. established.
