Accelerometers are instruments for measuring, displaying, and analyzing acceleration and vibration.
|
|
Ball valves provide tight shut-off and characterizable control. They have high rangeability due to the design of the regulating element, without the complications of side loads typical of butterfly or globe valves.
|
|
Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves.
|
|
Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system.
|
|
Diverter valves direct flow from one inlet to one of two or more outlets.
|
|
Drain valves are designed to automatically remove liquids from process lines as necessary.
|
|
Electric valve actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level.
|
|
Electro-pneumatic transducers convert current or voltage input signals to proportional output pressures. They are used as process control elements in valves, pneumatic relays, and flow regulators for applications such as spray and damper control.
|
|
Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.
|
|
Flow switches are devices that monitor flow and send a trip signal to other devices, like a pump, for protection. These switches can be used for the measurement of gases, liquids, and steam.
|
|
Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage.
|
|
Globe valves are linear motion valves with rounded bodies, from which their name is derived. They are widely used in industry to regulate fluid flow in both on/off and throttling service.
|
|
Industrial valves are classified in many different ways. They can be distinguished by material of construction, media handled, and/or application.
|
|
Liquid flow meters are used for measuring the flow or quantity of a moving fluid.
|
|
Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion.
|
|
Pressure sensors include all sensors, transducers and elements that produce an electrical signal proportional to pressure or changes in pressure.
|
|
Pressure switches are actuated by a change in the pressure of a liquid or gas. They activate electromechanical or solid-state switches upon reaching a specific pressure level.
|
|
Resistive temperature device (RTD) elements are wire windings or other thin-film serpentines that exhibit changes in resistance with changes in temperature. They are usually made of metallic elements or alloys such as copper, nickel, or nickel-iron.
|
|
Rotameters are typically tapered glass tubes positioned vertically in the fluid flow. A float within the tube rides upward in relation to the amount of flow.
|
|
RTD temperature probes convert the RTD resistance measurement to a current signal, eliminating the problems inherent in RTD signal transmission via lead resistance.
|
|
Resistance temperature detector (RTD) temperature transmitters convert RTD resistance measurements to current signals, eliminating the problems inherent in RTD signal transmission via lead resistance.
|
|
Sensor transmitters are measurement or signal conditioning packages that provide a standard, calibrated output from a sensor or transducer in the form of a current loop output (e.g., 4-20 mA).
|
|
Shock and vibration testing shakers are force generators or transducers that provide a vibration, shock, or modal excitation source for testing and analysis.
|
|
Strainers are placed in-line with process piping to remove large solid contaminants from the flow. Strainers can be cleaned and reused.
|
|
Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches.
|
|
Temperature probes are used in various temperature sensing applications. Technology options include thermocouple, RTD, thermistor and solid state style probes.
|
|
Thermistors are thermally-sensitive devices whose electrical resistance varies with temperature. Unlike RTDs and thermocouples, thermistors do not have standards associated with their resistance vs. temperature characteristics or curves.
|
|
Thermocouple temperature probes are bimetallic probes that are used in various temperature-sensing applications. They consist of two wires, each of which is made of a different metallic element or alloy.
|
|
Thermocouple temperature transmitters convert the small millivolt output of a thermocouple to a current signal (typically 4-20 mADC) that is immune to noise and voltage drops over a long distance.
|
|
Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes. They are typically used to control heating and cooling systems.
|
|
Turbine flow meters measure the rate of flow in a pipe or process line via a rotor that spins as the media passes through its blades.
|
|
Ultrasonic flow meters use sound waves to determine flow rates. They can be either Doppler Effect meters or Time-of-Flight meters.
|
|
Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source.
|
|
Vibration analysis systems are used for vibration testing and modal analysis, including the instrumentation to acquire data and/or analyze results.
|
|
Vibration instruments are used for measuring, displaying and analyzing vibration. Typically these instruments comprise a transducer, data acquisition and either a local display or some sort of output to a computer or another instrument.
|
|
Volumetric liquid flow switches measure the flow or quantity of a moving fluid in terms of a unit of volume per time, such as liters per minute. These flow sensing devices have a switch output.
|
|
Vortex flow meters are flow sensors that detect the frequency of vortices shed by a bluff body placed in a flow stream. The frequency of the vortices is proportional to the flow velocity.
