Analysis of problems in reed tube selection and application

　　(1) The elements of climate stress mainly refer to temperature, humidity, atmospheric pressure (altitude), coastal atmosphere (salt spray corrosion), sand and dust pollution, chemical atmosphere and electromagnetic interference. Taking into account the general applicability of the control system in various industries and natural environments throughout the country, reed pipe, selection, and application must take into account the particularity of reliable operation for many years, and the key parts of the control system must choose a fully sealed type with high insulation and strong electrical resistance (metal cover seal or plastic seal type, metal cover seal products are better than plastic seal products) reed pipe. Because only fully sealed RF sensors have excellent environmental resistance, good electrical contact performance and stable load switching ability (not affected by the external environment).

　　(2) Mechanical stress action elements mainly reed tube, selection, application refers to vibration, impact, collision and other stress effects. The main consideration of the control system is the ability to resist seismic stress and mechanical stress, and the small reed pipe with balanced armature mechanism should be selected.

　　(3) The input parameters of the excitation coil mainly refer to overexcitation, underexcitation, low-voltage excitation and high-voltage (220V) output isolation, the influence of temperature changes, long-distance wired excitation, electromagnetic interference and other factors, which are factors that must be seriously considered to ensure the reliable operation of the control system. It is necessary to motivate the system according to the excitation quantity stipulated by the reed dryer to ensure the stable and reliable operation of the system.

　　(4) Contact output (change circuit) parameter elements mainly refer to the nature of contact load, such as lamp load, capacitive load, motor load, inductor, contactor (RF sensor) coil, choke load, resistive load, etc. Contact load value (open-circuit voltage value, closed-circuit current value), such as low-level load, dry circuit load, small current load, large current load, etc.

　　Selecting the appropriate RF sensor according to the load nature and load capacity of the device being driven is the basic condition for the reliable operation of the RF sensor. Whether the RF sensor works reliably or not mainly refers to whether the contact can complete the specified circuit switching function. If the actual load capacity of the switched reed tube, selection, and application is greater than the switching load capacity specified by the selected RF sensor, the RF sensor cannot work reliably.
