What is the power sensor?

The force sensor converts the measured forces representing the strength, weight and pressure on the transmitted output signals. These signals can be sent to indicators, controllers, or data collection systems connected to computers. Most force converters have either analog or digital electronic, pneumatic or hydraulic outputs depending on the application needs. The force converter can be as small as the head of the pin, measuring mere gram of power (1/28. One ounce) or as large as the column of the bridge, measures hundreds of tons (1 tonnes equal to 2000 pounds or 909 kilograms).

Early power converters were hydraulic. The cylinders, bellows or membranes converted forces into pressure signals that were read on indicator meters. The advantage of hydraulics is that the meters of indicators at different locations on the same line allowed several people to obtain and use information at the same time. Another is that hydraulics are by their very nature sealed systems, which makes them generally rough, and impermeable for water and other contaminanty.

Later, converter systems with pneumatic outputs began to be used, allowing easy integration into pneumatic processes control systems using a universal output Convention 3-15 PSI. Many hydraulic systems have only installed the pneumatic pressure transmitter in the hydraulic hose from the hydraulic power converter. Pneumatic force converters were also widely used to direct the winding brake on rolling machines in the paper industry.

Advances in the art of tension sensors since the 1950s have changed the way the forces would be measured. A decreased element was based on the relationship between electrical resistance and extension, twisting or other physical distortion of conductive fiber wire, foil or thin film from its normal rest position. When these wires were associated with Beams, Pins, Shafts or Plates allowed the implementation of high -precision, repeatableand the harsh systems of the forces converter called freight cells. They would be applied to every area of ​​human business from industry and trade for transport, health care, scientific research and personal electronics. They are used in weight containers, scales and for medical measurements such as blood pressure.

Systems

network converters based on measuring sensors or voltage load are generally cheap. They include voltage excitation for the sensor and the leveling bridge circuit, amplifier section, scaling and conditioning electronics for output. Analog outputs can range from direct current voltage (DC), which prevail scientific, medical and defense applications, to standard DC current outputs 4-20 million for industrial control systems. The strength sensors directly connected to computers and multiplexers may include the RS-232 serial interfaces, the Universal Rial Bus (USB) and industrial data highways such as Modbus®.
