An Air Compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible, so the main action of a pump is to pressurize and transport liquids.
A Positive Displacement Meter is a type of Flow Meter that requires the fluid being measured to mechanically displace components in the meter in order for any fluid flow to occur. Positive displacement (PD) flow meters make volumetric flow measurements taking finite increments or volumes of the fluid.
An Aerial Device or Elevating Work Platform is a mechanical device used to provide temporary access for people or equipment to inaccessible areas, usually at height. They are generally used for temporary, flexible access purposes such as maintenance and construction work or by fire fighters for emergency access, which distinguishes them from permanent access equipment such as elevators.
Belt Conveyor moves an object from one point to another consist of two or more pulleys, with a continuous loop of material - the conveyor belt - that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the un-powered pulley is called the idler.
A sensor is a device, which receives and responds to a signal or stimulus. The "stimulus" means a property or a quantity that needs to be converted into electrical form. Hence, sensor can be defined as a device, which receives a signal and converts it into electrical form, which can be further used for electronic devices.
A Crane is a lifting machine, generally equipped with a winder (also called a wire rope drum), wire ropes or chains and sheaves that can be used both to lift and lower materials and to move them horizontally. It uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human.
A Furnace is a device used for heating. The term furnace is used exclusively to mean industrial furnaces which are used for many things, such as the extraction of metal from ore (smelting) or in oil refineries and other chemical plants, for example as the heat source for fractional distillation columns.
A Heater is any object that emits heat or causes another body to achieve a higher temperature. In a household or domestic setting, heaters are usually appliances whose purpose is to generate heating (i.e. warmth). Ceramic elements are the heaters of choice in most applications, but quartz heaters are favoured in industrial applications where rapid heater response is necessary. Quartz heaters provide infrared radiation in the medium wavelength of 1.5 to 5.6 microns.
An Electric Motor uses electrical energy to produce mechanical energy, very typically through the interaction of magnetic fields and current-carrying conductors. The reverse process, producing electrical energy from mechanical energy, is accomplished by a generator or dynamo.
A spring is an elastic object used to store mechanical energy. Springs are usually made out of hardened steel. Small springs can be wound from pre-hardened stock, while larger ones are made from annealed steel and hardened after fabrication. Some non-ferrous metals are also used including phosphor bronze and titanium for parts requiring corrosion resistance and beryllium copper for springs carrying electrical current (because of its low electrical resistance).
