UE switch agent J400-451 J402-451 J403-451 J400-451 0-19.9KPa 1*SPDT  J402-451  0-19.9KPa 2*SPDT Two alarm points dead zone will increaseJ403-451  0-19.9KPa  3*The dead zone of the three alarm points ofSPDT  nitrile rubber diaphragm and O-ring pressure port 1/4NPT inner wire aluminum port The maximum working pressure is 0.2bar when it rises, it is the set point range When the high pressure end falls, it is the set point range Maximum withstand pressure 1.55MPa    The mechanical pressure switch is a purely mechanical deformation that causes the action of the micro switch. When the pressure increases, the different sensing pressure components (diaphragm, bellows, piston) will be deformed and will move upwards. Through the mechanical structure such as the railing spring, the uppermost micro switch will be activated to output the electrical signal. Control the pump start and stop  switch to control the start and stop of the pump. In the process, the pump is generally used as a power source to control the pressure in a specific area within the (a, b) interval, and the switch outputs a switching signal whether it reaches point a or b.  Option 1: H100-15731~15737, adjustable dead zone, SPDT output, the opening and closing of the switch point can directly control the start and stop of the pump. Disadvantage: no stock, the set point is easy to drift up to 10% of the set point. On-site calibration capability is required. Advantage: there is no need to add a logic controller in the middle, and there will be no switch point dead zone > ba range. question.  Option two: J402, 2 SPDT outputs. Disadvantage, it is necessary to add a logic relay to output signals when two points act at the same time. Advantage: no drift when ba>c.
