HC-Y810 Digital Pressure Gauge Digital Intelligent Pressure Gauge Pump Negative Pressure Water Pressure Switch Controller DC12V 1PC Use Note:If the load exceeds 750w,make sure to use the range of contactor .Choose the rang of 1.5-2 times the actual pressure to prevent the medium with corrosiveness and flammablity to 304 stainless steel from overpressure Colour: Black and YellowPower supply:DC12VPressure Range:0-1.6Mpa(0-16kg/cm2=0-16Bar≈0-232Psi)Temperature Range:-30~+85℃Sampling Rate:5 times/secPort Size: M20X1.5Product Size: 80X115X48mmPackage Content : 1Pc x HC-Y810 Digital Pressure Gauge 1-Time dalay Control:When the Preessure reaches the action point,the delay action and the delay time can be set. Effect:It can prevent the unstable pressure in the pipe and cause the motor to move frequently 2-Password protection:Lock Parameter settings are not modiffied Effect:protect settings from modification 3-Reverse Control:When the pressure is lower than the lower limit,the contacts are disconnected after the function is opened when the pressure is higher thand the upper limit,the contacts are closed.Effect:High start low stop 4-Pressure protection:When the pressure change can not be detected within the set time,the pump is automatically disconnected showing E--1,and automatically restart when the pressure changes. Effect:Avoid water shutdowm due to water source drying,pipeline leakage, resulting in pressure not up to the upper limit pump idle 5-Water Shortage Protection:When the water pressure is lowerthan the set water-shortage protection value,the motor will be automatically closed showing E--F.After protection,it needs to start work manuallyEffect:Avoid water shortage,pump idle operation 6-Checking time:Setting Pressure inspection protection and water shortage protection time. Effect:Cooperate with pressure check protection and water shotage protection Warm tip: We also have other models, If you need other voltage(DC24V AC220V,AC110V AC380), Product default connector:M20x1.5, We also have(G1/4'' G3/8'' G1/2'' NPT1/4'' NPT3/8'' ) Please contact us,we will best price to you.
