Installation Suggestions
1.When installing the sensor,ensure that the transmitting surface of the transducer is parallel to the measured plane, so as to ensure that the sound waves emitted vertically to the surface of the measured object return with maximum energy to ensure maximum range stability and reliability;
2.In front of the sensor,it should be noted that except for the measured object,other objects should avoid the sensor testing range;
3.There is steam at the site of use and installation,and water droplets are easy to adhere to the surface of the probe, so try to avoid the influence of water droplets;
4.The installation and fixation of the sensor needs to avoid structural deformation, metal or other resonance, and avoid resistance components such as elbows, valves, variable diameters;
5.The installation height of the ground or obstacle objects and the module is recommended. The actual module installation height can refer to the above effective detection range reference diagram, and select the appropriate installation height according to the range of different angle requirements.
