The present disclosure relates to chain monitoring systems and methods. In particular, the chain monitoring system is configured to mount onto a portion of a chain and measure one or more parameters associated with one or more characteristics of the chain. The measured parameters are processed by the chain monitoring system and/or transmitted to a remote system for analysis. The analysis may be used to determine a characteristic and/or change in the characteristic of the chain. In some examples, the characteristic is an elongation value associated with the chain, which can be transmitted to a networked system for analysis, display, and/or control. In some examples, a sensor can be employed to measure one or more characteristics of the chain. The sensor may include, but is not limited to, a strain gauge, an accelerometer, an optical, a sonic, and/or a magnetic sensor.

The invention relates to a transport device (100), in particular for transporting product carriers in a plant for manufacturing food products. The transport device (100) comprises at least one chain (1) to which measuring marks (4) are attached, an electrical drive system (20) for driving the chain (1) with a servo motor (25) and an absolute encoder (21), a plant control unit (30) and a measuring sensor (11) for detecting the measuring marks (4) with a switching frequency of greater than 2000/s. The plant control unit (30) comprises a first input (34) for receiving measurement data from the measuring sensor (11) and a second input (35) for receiving position data from the position sensor (21) and is designed to receive data from the measuring sensor (11) and from the position sensor (21), to mutually correlate said data correctly with respect to time, to determine therefrom lengths between measurement marks (4), more particularly between two consecutive measurement marks, and to produce a signal which provides information about the quality of the chain. A servo position actual value is ascertained by means of oversampling. (FIG. 2)

A smart belt and a control method thereof are provided, in which a belt device is provided, including a strap portion comprising a plurality of magnet patterns, a first sensor portion configured to sense one of the plurality of magnet patterns while the strap portion is being fastened to a buckle portion, and a controller configured to obtain a length of a waist circumference of a user that corresponds to the magnet pattern sensed by the first sensor portion. The belt apparatus may additionally include a clip portion connecting the strap portion with the buckle portion, and a second sensor portion configured to measure a tension exerted on the clip portion while the strap portion is being fastened to the buckle portion. The controller may correct the length of the waist circumference using a waist circumference correction value corresponding to the measured tension.

The invention relates to a chain elongation monitoring device having a first differential transformer, a second differential transformer, and a control for recording the measured values, wherein the second differential transformer is arranged at a fixed distance from the first differential transformer, and a method for operating the chain elongation monitoring device.

A system and method for determining a change in a thickness and temperature of a surface of a material are disclosed herein. The system and the method are usable in a thermal protection system of a space vehicle, such as an aeroshell of a space vehicle. The system and method may incorporate micro electric sensors arranged in a ladder network and capacitor strip sensors. Corrosion or ablation causes a change in an electrical property of the sensors. An amount of or rate of the corrosion or the ablation and a temperature of the material is determined based on the change of the electrical property of the sensors.

A sensor for measuring a thickness of a layer of a grain/residue mixture as the layer is transported through a cleaning arrangement of a combine harvester. The sensor is mounted on a support surface of a grain pan or a sieve of the cleaning arrangement and comprises a tower-shaped support structure with sensor elements attached to the structure and forming a vertical stack of sensor elements, so that a number of sensor elements is submerged in the layer and a number of sensor elements extends above the layer. The sensor elements are configured to measure an electrical property that changes as a function of immediate surroundings of the sensor elements. The sensor elements are configured to be read out independently from each other.

An apparatus comprises a housing and a plurality of electrical contacts. Each of the plurality of electrical contacts are arranged to sequentially contact a contact device as the contact device moves through the housing. The contact device comprises a first end configured to couple to a bolt, a second end opposite the first end, and a conductive region between a first insulated region and a second insulated region.

A capacitive distance sensor includes a sensor element having an electrically conductive, elongated, flat sensor area which in turn contains a number of holes. The sensor area is completely surrounded by an electrically non-conductive insulating body, with the result that the insulating body completely covers the edge regions of the holes. The sensor element is produced, in particular, by first of all making the holes in the sensor area. In a subsequent step, the sensor area is completely encased by the insulating body which also completely fills the holes in the sensor area.

A frequency characteristics measurer is disposed in the vicinity of an end of refrigerant piping, the end of which is connected to an outdoor unit, that connects the outdoor unit and an indoor unit of an air conditioner, and measures frequency characteristics of the refrigerant piping. A filter is attached at a position between the outdoor unit and a position where a terminal of the frequency characteristics measurer is connected, so as to wrap the refrigerant piping. A piping length calculator is connected to the frequency characteristics measurer via an interface cable, and acquires, via the interface cable, frequency characteristics measured by means of the frequency characteristics measurer. The piping length calculator extracts a lowest anti-resonant frequency from the acquired frequency characteristics, and calculates the length of the refrigerant piping on the basis of the extracted lowest anti-resonant frequency.
