Abstract Discal tightwire hammer sensors used in valve′s hydraulic pressure switches in Jianbi Pumping Station were discussed,its limitation was analyzed,and other usual sensors characteristics were compared.Discal rubber sensors are prior to be selected at the requirements of Jianbi pumping station.Controlling principle and ways of parameters setting are described in details.In addition,outlet valves switches′ testing results of the No.3 pump show that sensors and switches controlling windage is less than 0.5% of criterions.Discal rubber sensors are tested to be capable of meeting expectations of linking valves with pumps,through running on-line for years.Its improving measures are also suggested to ensure the pumping station′s safety and reliability.sensor;pumping station;valve;hydraulic pressure switch
