Instrumentation & Sensors

Flow meters are devices that measure the flow rate of a liquid or a gas as it passes through a pipe. They can measure everything from temperature, density, pressure, vapor pressure and viscosity. Flow meters can also be used to monitor safety conditions.

Level switches are devices that are used to monitor the level of a substance within a system, usually a reservoir or a tank. When the substance is outside of the set parameters (low or high), the switch can trigger an alarm to signal the system to modify the level (open a valve or start a pump).

Pressure sensors are devices that measure the pressure in liquids or gases and then, based on that information, will generate an electronic signal.

Pressure transmitters are devices that can measure pressure ranges in liquids or gases. The value is then transmitted as an electronic signal.

Light curtains can be used instead of a solid guard to protect personnel around hazardous machines. The light curtain uses presence detection between a transmitter and a receiver. When a presence is detected, a signal would be sent to turn off the machine to prevent injury.

Limit switches are electromechanical devices that detect the presence or absence of an object or to detect when the movement limits of an object have been exceeded.

Photoelectric sensors emit a beam of infrared or visible light that is used to detect whether an object is present or absent, or whether there are changes in surface conditions. When the light is interrupted or reflected by the object, the change in the amount of light arrives at the receiver. The receiver converts the change to an electrical output signal.
