The pressure range of this sensor is 0-5BAR,with the insulate double thread fitting is M4, and the corresponding resistance value is the conventional 10-184 Ω and M10X1.0 without Alarm. When the pressure changes, the resistance value inside the sensor will change accordingly, and the different resistance values will be transmitted to the controller. The shell and the equipment are connected and grounded, and there is no low-voltage alarm function. The appearance adopts the form of iron galvanized, has the function of rust prevention, can be stored and used for a long time.
