There is no data signal in E14 displayed by radar level gauge

Radar level gauge The display information E14 indicates that there is no radar echo data signal, and there are many reasons for this situation
1. There are many reasons for installation problems, such as location, docking, orientation, etc. the way to distinguish whether the installation problem is or not can be determined according to the "radar echo curve of information displayed on the spot". Another way, such as the instrument panel is available, can distinguish the instrument panel from the external obstacles. The compressive strength of radar echo can be damaged if the wave energy of radar detection can not be transmitted out or the inclination angle is not vertical to the obstacle. On the spot work situation did not grasp clearly also is likely to cause.
2. Steam and crystal adhesion can also lead to E14, which is easy to distinguish. Remove the instrument panel to observe the resolution of part of the wireless antenna, or the radar echo is normal after cleaning.
3. The main problem of model selection is that the model and specification of instrument panel are not suitable, which leads to weak radar echo. The radar echo data signal is greatly related to the relative permittivity, measurement range and smoke vapor.

4. It is difficult to adjust the setting of main parameters. Radar echo has certain compressive strength, but because the basic parameters are unscientific, such as too large "threshold", E14 can also be caused;
5. Poor security protection of the instrument panel, such as the cable gland is not tightened, leading to water seepage in part of the wireless antenna of the instrument panel. Open the instrument panel to observe carefully or use the instrument panel to point to the external obstacles to distinguish this common fault.
6. The common faults of the power supply circuit of the instrument panel, such as empty solder joints in the power supply circuit, can be distinguished according to the "radar echo curve diagram" or the lower dashboard, which can be distinguished by pointing the instrument panel to the external obstacles.
to make a long story short, Radar level gauge The common faults of E14 are very complex. For example, E14 appears in a short time, but it is also caused by inadvertent influence. As an anti-interference countermeasure, the instrument panel can be regarded as normal operation at this time.
Radar level gauge Distinguish whether the common fault of E14 is caused by the instrument panel itself or the installation in natural environment; if the common fault of E14 is caused by the instrument panel itself, it is necessary to further distinguish whether it is caused by the problem of power circuit module or water seepage, installation short circuit, etc., if it is the former one, it can be solved according to the replacement of power circuit module; if it is the latter, it is better to repair and repair. If it is difficult to distinguish the model selection, it is only necessary to replace the model specification; if it is a difficult installation problem, it must be communicated with the on-the-spot communication, change and solve according to the installation method.
