Displacer Level Switch Working Principle
Displacer controls offer alternative features to the float-operated control. The sensor is a weight (displacer), heavier than the liquid, that is suspended by a spring. When liquid contacts the displacer,...

Differential Pressure Switch Working Principle
A Differential Pressure Switch, just like a regular pressure switch, is a simple electro-mechanical device that operates on the basic principles of levers and opposite forces. Mainly, they are used for...
Float Level Switch Working Principle
Float Operated Level Switches Principle: All float operated liquid level controls operate on the basic buoyancy principle which states “the buoyancy force action on an object is equal to the...
Thermistor Working Principle
Thermistors Thermistors are temperature sensitive semiconductors that exhibit a large change in resistance over a relatively small range of temperature. There are two main types of thermistors, positive temperature coefficient...
Resistance Temperature Detectors Working Principle
Resistance Temperature Detectors (RTD) Working Principle Thermo-resistive Temperature Measuring Devices A change in temperature causes the electrical resistance of a material to change. The resistance change is measured to infer...
Thermocouple Working Principle
THERMOCOUPLES A thermocouple is made up of two dissimilar metals, joined together at one end, that produce a voltage (expressed in millivolts) with a change in temperature. The junction of...
Mechanical Temperature Measuring Sensors
Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic. There are four basic types of temperature...
Tilt Level Switch Working Principle
Tilt Switches Monitor’s line of tilt bin level switches are economical, trouble-free point level controls available for detection of dry bulk materials. The units can be used as high level indicators...
Temperature Switch Working Principle
Temperature is a measure of the average heat or thermal energy of the particles in a substance. Since it is an average measurement, it does not depend on the number...
In Line Flow Switch Working Principle Animation
In Line Flow Switch are comprised of two main assemblies: the housing and the shuttle assembly. As liquid flow enters the flow switch, it passes through an orifice between the...
