Product Details


                                    Pressure switch H121 -550  H122-554


Feature :

1, the core of the product using the new intelligent micro-processing chip, stable and functional and 

     practical performance.
 2, LED displays the current pressure or level value;
 3, the pressure or level can be set to start or stop according to their needs;
 4, four LED products according to customer needs three units can choose: Mpa, KG.F / CM2, PSI
 5, can be set high and low pressure or level alarm, and relay or optocoupler output to the control device;

      dual relay  output (SPDT) switch;
 6, two-way relay / two-way coupler / with 4-20mA / 0-10V output can be selected;
 7, the use of high-precision pressure sensors, high precision than mechanical pressure switches, small hysteresis,

     fast response, stable and reliable; no dead zone adjustment, can be set relay pressure points over the entire

      measuring range;
 8, use the buttons to adjust the operating pressure, easy to use, more flexible; degree of protection: IP65, it can be 

     used in harsh environment applications;
