Newer digital thermostats have no moving parts to measure temperature, instead relying on thermistors or other semiconductor devices such as resistance thermometers (resistance temperature detectors). Usually one or more normal batteries must be installed to run it, and while some so called "power s Read More
A thermostat is a regulating device component that senses the temperature of a physical system and acts so that the temperature of the system remains near a desired set point.A thermostat is used to heat or cool any device or system to a set point temperature. Examples include building heating, cent Read More
Early technologies included mercury thermometers with electrodes inserted directly into the glass so that when a certain (fixed) temperature was reached, the contacts were closed by the mercury. These are accurate over a range of temperatures.Common sensor technologies in use today include:• Bimetal Read More
A magnetic level gauge is a level sensor, that is, a device used to measure the level of a fluid. Magnetic level gauges consist of a "floatable" device that can float in both high and low density fluids. Magnetic level gauges can also be designed for harsh ambient conditions up to 210 bar at 370 °C. Read More
Level sensors detect the level of liquids and other fluids as well as fluidized solids, including slurries, granular materials and powders with an upper free surface. A flowing substance becomes essentially horizontal in its container (or other physical boundary) due to gravity, while most bulk soli Read More
Typical systems for mid-point level detection in liquids include magnetic and mechanical floats, pressure transducers, conductive sensing or electrostatic (capacitive or inductive) detectors – as well as electromagnetic (e.g. magnetostrictive) measurement signals flying to the surface of the fluid t Read More

Metal and water have been known to be excellent reflectors of radio signals since the late 1800s, and attempts have been made over the years to build ships, trains and iceberg detectors since then. Most of these have obvious practical limitations, especially with low frequency signals that require l Read More
A radar altimeter (RA), also known as a radio altimeter (RALT), electronic altimeter, reflection altimeter, or low-range radio altimeter (LRRA), measures altitude above terrain beneath an aircraft or spacecraft by timing how long it takes a radio beam to travel to ground, reflect and return to the a Read More
Digital pressure gauge is a new type of intelligent and multi-functional measuring instrument integrating sensing technology, electronic technology and microcomputer technology. Read More
The positive and negative values of the flow can be measured and recorded on the data, and the flowmeter will store the positive and negative cumulants to ensure the accuracy of the net cumulants of the measured flow. Read More
