A warning device () of abnormal operation of belt conveyor () has a pair of rotating mechanisms () disposed oppositely at two sides of a conveyor belt (). The rotating mechanism () includes a rotating component () and a rotating body. The rotating bodyhas a fixed end () and a movable end (). A pair of first sensor switches () is disposed on the rotating bodies (). The first sensor switch () emits a first signal when activated and emits a second signal when being triggered. The rotating body () triggers the first sensor switch () when the conveyor belt () is abnormal. The first sensor switch () is triggered and emits the second signal for warning.

A flexible float-type liquid level measurement device includes an outer tube securement member, a signal connection module, a flexible outer tube, a suspension member, a flexible supporting unit and a magnetic floating ball. The signal connection module is arranged on one end of the outer tube securement member. The flexible outer tube is connected to the outer tube securement member. The suspension member is connected to another end of the flexible outer tube. The flexible supporting unit is arranged inside the flexible outer tube, and the flexible supporting unit includes one end connected to the outer tube securement member and another end connected to the suspension member. The magnetic floating ball is moveably mounted onto the flexible outer tube. Accordingly, the elongated deformation of the flexible outer tube can be prevented while the measurement accuracy and useful lifetime of the measurement device can be increased.

A measurement device for detecting a material level and a temperature has a cable, a level sensing module, a thermal sensing module, a processing module, and a power module. The measurement device detects difference of currents between an electrode of the cable and the earth, and calculates a material level of a material stored in a silo according to the RF admittance. The cable comprises a plurality of thermal sensing units for detecting a temperature of the material. The measurement device further calibrates a material capacitance of the material with the temperature for avoiding an error caused by an inaccurate parameter.

A magnetic sensing switch includes switch body having a hollow tube and an opening. A magnetic reed switch is disposed in the tube and includes two conductive points. The plug having an elastic clamping force is fixed in the opening by interference fit. The plug including a sealant injection portion and a retaining portion communicating with the tube. The two wires are inserted in the tube, one end of each wire is connected to one conductive point, and the other end passes through the retaining portion to protrude out of the tube. A sealant is injected into the tube via the sealant injection portion to entirely wrap the magnetic reed switch and the wires inside the tube, and the sealant partially protrudes out of the sealant injection portion.

A cable-base sensor can detect a material level and temperatures of a material stored in a silo. The cable-base sensor comprises an electronic box, a cable, a stopper, and a signal processing module. The electronic box comprises a base and a space for containing the signal processing module, and a hole is formed through a bottom of the electronic box. The base is mounted in the bottom, and a tapered hole is formed through the base. A first end of the cable extents into the tapered hole and the hole, and spreads to form a cable bud. The stopper is a tapered block and pressed into the tapered hole for enforcing the cable bud to be sandwiched between the stopper and the base. The cable bud strengthens a connection between the electronic box and the cable for preventing damages from solid materials.

A level measuring device with an integratable lens has a radar level meter and an angle adjusting assembly. The radar level meter has a horn antenna and a lens antenna assembly mounted on a signal transceiving end of the radar level meter. The lens antenna assembly has a housing and a lens antenna. The housing is hollow and receives the horn antenna therein. One end of the housing is connected to the lens antenna, and the other end of the housing is connected to the signal transceiving end of the radar level meter. The angle adjustment assembly is mounted around the housing. As the lens antenna assembly covers the horn antenna, the horn antenna is less likely to be damaged. Additionally, the housing of the lens antenna assembly is connected with the angle adjusting assembly for angle adjustment of the combined horn antenna and lens antenna assembly.

A sealing device of a level meter is acid-and-alkali-resistant and pressure-resistant, and has a flexible outer tube, a plug, a female union connector and a male union connector. The flexible outer tube has an expansion neck formed on a bottom end thereof. The plug is mounted in the expansion neck. The female union connector is mounted around the expansion neck. The male union connector engages the female union connector by means of threaded engagement. The male union connector has a through hole for tying a weight such that the flexible outer tube is stretched along a force of a gravitational force of the weight. As being wholly and uniformly subjected to the gravitational force of the weight, the male union connector is less damage-prone. Accordingly, the tensile strength of the level meter is effectively increased, and a life duration of the level meter therefore prolongs.

A rotary paddle level switch has a housing, a driving unit, two switches, a resilient member, a clutch, a transmission shaft, and a propeller. A resilient clip of the clutch holds a non-circular actuation section of the transmission shaft. When the driving unit drives the clutch to rotate, the transmission shaft and the propeller are driven by the clutch. When the propeller is rapidly rotated by suddenly exerting an excessively large external force thereon, as the resilient clip holds the transmission shaft by elastic force, the fast rotating transmission shaft removes itself from the holding of the resilient clip and is rotated without driving the resilient clip to rotate, thereby avoiding the transmission of the external force and damage to the driving unit. As the clutch just needs a clutch stand and a resilient clip to achieve the foregoing function, the level switch is structurally simple and relatively inexpensive.

A metallic ball has a sliding sleeve, a shell, at least one magnet and a mounting bracket. The sliding sleeve has an open upper end, an open lower end and an outer surface. The shell is spherical, is mounted securely around the sliding sleeve between the open upper end and the open lower end of the sliding sleeve and has a reinforcing disk mounted around the outer surface of the sliding sleeve and has a top surface and may have a protruding portion. The magnet is on the top surface of the reinforcing disk. The mounting bracket is mounted around the sliding sleeve and on the top surface of the reinforcing disk to cover the magnet and has a wall extending toward and engaging the reinforcing disk and completely covering the magnet to effectively avoid the magnet being broken or damaged.
