A detecting element that is intended to sense rotational speed.

A router is a computer networking device that forwards data packets toward their destinations through a process known as routing. Routing occurs at layer 3 (Network layer) of the OSI seven-layer model.

A physical object that is a pressure relieving device designed to burst at a calibrated pressure to prevent pressure in systems or vessels from reaching unsafe levels.

Safety barriers are devices that limit the current, voltage, and total energy delivered to a sensor in a hazardous area or flammable environment in order to prevent an explosion.

An information object that indicates the location of safety signs and other relevant safety information.

A shower intended for emergency situations.

An information object with a symbol representing some hazard or safety information.

A sample loop adds a predetermined volume to the process.

A physical object intended to be used to collect and contain representative specimens or selections.

A detector intended to detect sand in a fluid.

Is a waste management facility where solid waste is isolated from the environment through engineered methods such as lining the base to prevent leachate seepage and covering disposed waste with layers of soil to reduce the risk of contamination.

Equipment used to allow drainage of foul water.

A system that provides voice and telefax communication via satellites.

A physical object intended to mechanically remove a deposit from a surface.

Is a filtration device used to remove coarse solids, debris, algae, aquatic weeds, fish, and floating solids from raw water entering a municipal or industrial water treatment plant.

A compactor is a machine or mechanism used to reduce the size of waste material.

Is a conveyer intended to move dry, solid material from one location to another by means of a helix or screw rotating in a cylindrical conduit.

A physical object intended to reduce or prevent the passage of fluid through an opening.

Equipment used for room separation.

A manual control switch which has more then two possible positioning states.

A valve that includes a means of operation (e.g. spring / gravity / fluid pressure / counter balance), and is not depending on an external source of energy.

A 'device' intended to separate different types of substances.

Is a computer or device on a network that provides functionality, services, or data to other computers or devices (clients) as part of client-server architecture.

A tank gauge that is intended to intermittently lower a displacer to measure a liquid level, bottom level, interface level or density.

Is a facility containing pumps and equipment for moving sewage from lower to higher elevation, particularly where the elevation of the source is not sufficient for gravity flow.
