摘要： A method for measuring a permittivity (ε) of a material (30) includes following steps. A sensing rod (14) of a material level sensor (10) inserts into a tank (20). The material level sensor (10) proceeds with a material level measurement of the material (30) to obtain a first feature value. The material level sensor (10) is vertically moved with a vertical distance (Hair). The material level sensor (10) proceeds with the material level measurement to obtain a second feature value, and subtracts the first feature value by the second feature value to obtain a feature value variation, and calculates the feature value variation to obtain the permittivity (ε) of the material (30).

摘要： A material level indicator includes a probe, first and second signal compensating units, arranged at first and second ends of the probe respectively, and a controlling module arranged at the first end and includes a signal processor, a signal emitter, and a signal receiver. The second end is opposite to the first end. The signal processor is connected to the signal emitter and the signal receiver. The signal emitter emits an electromagnetic signal from the first end to the second end of the probe. The first and second signal compensating units reflect the electromagnetic signal, and the signal processor generates first and second time interval differences according to the reflected electromagnetic signal received by the signal receiver. The signal processor calibrates an environmental coefficient and indicates a dielectric coefficient of the material according to the first and second time interval differences respectively.

摘要： A self-alignment filling level detecting device has a reflector and a sensor detachable from each other. The sensor has a light emitter, a light sensor, and a controller. The light sensor receives different light intensities when the reflector is assembled to the sensor and when the reflector is not assembled to the sensor. Thus, the controller determines whether the reflector has been accurately engaged and aligned with the sensor or not based on sensing results of the light sensor. Since the reflector and the sensor are detachable from each other, either the reflector or the sensor can be replaced individually if any one of them malfunctions.

摘要： A plumb probe assembly for a level measuring device has a plumb and a connection assembly. The plumb has an inner connecting tube. The connection assembly has two connectors and two clip brackets. The connectors are slidably mounted together while one of the connector firmly connects to the inner connecting tube of the plumb. The clip brackets are movably connected together by at least one resilient device supplying a clipping force and clip around the connectors to hold connectors firmly together. When a force greater than the clipping force, applied to the plumb, the clip brackets separate and the plumb falls into the particulates in the container. The plumb will not cause damage to a particulate discharging device and will disconnect with the connection assembly. A replacement plumb may then be attached to the connection assembly for continued operation.

摘要： A microwave coupling moisture content sensor and a method for deriving a linear regression correlation between signal data generated by a microwave moisture content sensor and moisture contents of objects are disclosed. The microwave coupling moisture content sensor includes a microwave resonator and a signal feeding member or a microwave emitting member. An object is placed outside the microwave resonator, and the signal feeding member or the microwave emitting member emits microwaves, which penetrate the object. The resonance frequency and the amplitude of the microwave resonator are measured to obtain the moisture content of the object. Several objects having known moisture contents are detected by the microwave coupling moisture content sensor to obtain corresponding resonance frequency and amplitude. Correlation coefficients of several combinations are calculated, and the combinations having low correlation coefficients are removed, whereby the best linear regression correlation is derived for the measurement of moisture contents of objects.
