CONSTITUTION:When there is an outside voltage E2, a resistance Rx can be determined by the formula: Rx={(E1+E2)/VR2}XR2-R1-R2. In this case, however, E2 is an unknown quantity. Therefore, first the measurement of voltage is conducted in the state of a contact r without operating ...
The aim of this project is to design, build and test a temperature sensing system. The system was designed to measure a temperature range of 0 to 100 °C. A PT100 was used to measure the temperature, and it is a resistance temperature detector (RTD) that changes its resistance depending ...
(slider) of the potentiometer until the difference between the voltages across the fixed resistance and across the potentiometer is equal to zero, i.e. the potentiometer is balanced out. The position of the potentiometer slider in this balanced position is a measure for the quotients of the ...
As known, the capacitance influences the resistance impedance of the cable. From GB 2 003 613 it has become known to measure the capacitance of a cable in that a measuring tube of electrically conductive material is provided through which the cable is extend. Preferably, the measuring tube is...
Both the resistance strain sensor and mechanical sensor measure the strain at different depths of the bolt, and then solve the stress through the relevant calculation method [5,6]. The stress is obtained by measuring the change in the vibration frequency of the steel string after the sensor is...
In this paper, based on grey system theory, a prediction method with feedback influence is proposed and the WOA is used to determine the unknown background value parameters in it. (2) By using three sensors’ data to show that the new grey prediction model has a smaller mean absolute ...
Why is it necessary to measure the average resistance/unit length of the wire? Why the compound pendulum does not oscillate at the central hole? A pendulum is the timing device for a clock. The clock is running fast and it is desired to slow the pendulum...
changing either the electrical resistance if the sensor is a potentiometer, or causing electrical pulses to be sent to a data recording unit if the sensor is a pulse-counting device (often called a shaft encoder). The output of the sensor in the stilling well commonly is set to be equal ...
rated for water resistance that enhances durability and simplifies cleanup procedures. A Traditional Handheld Refractometer does not require batteries or a power source. This allows the handheld refractometer to be used anywhere, at least in daylight. ...
