Air velocity flow sensors measure air velocity or volume flow using insertion probes or capture hoods.
|
|
Audible alarms provide an audible indication of a hazardous situation.
|
|
Centrifugal pumps consist of a set of rotating vanes, enclosed within a housing or casing, that are used to impart energy to a fluid through centrifugal force.
|
|
Computers are programmable electronic devices that accept data, execute prerecorded instructions, perform mathematical and logical operations, and output results.
|
|
Conductivity electrodes are devices that measure the salinity and conductivity of water samples.
|
|
Data acquisition is the digitizing and processing of multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes. Signal conditioning includes the amplification, filtering, converting, and other processes required to make sensor output suitable for rereading by computer boards.
|
|
Data loggers and data recorders acquire digital data from sensors and other signals. They are primarily used to store data for subsequent downloads to a host PC, but may also include real-time features such as monitors and alarms.
|
|
Diaphragm pumps use a diaphragm that moves back and forth to transport liquids from one place to another.
|
|
Dissolved oxygen meters are analytical instruments that are used to measure the amount of oxygen dissolved in a liquid sample.
|
|
Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.
|
|
Gear pumps use intermeshing gears to pump various types of liquids. Typically, one gear is the driver and the other is free wheeling. The gears have very tight tolerances so that the fluid being pumped cannot pass through them. Common uses for gear pumps include high pressure, metering, and flow control applications.

|
Humidity measurement instruments test for absolute humidity, relative humidity, or dew point in air.
|
|
Industrial computers are similar to personal computers (PC), but they are intended for use on a factory floor or in other harsh environments.
|
|
Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).
|
|
Ion specific electrode meters are millivolt meters that interface with ion selective electrodes (ISEs). These meters take the potential generated by the electrode and convert it into units of concentration.
|
|
Liquid flow meters are used for measuring the flow or quantity of a moving fluid.
|
|
Moisture meters are used to measure the moisture content in bulk solids, liquids and gases.
|
|
Noncontact infrared temperature sensors absorb ambient infrared (IR) radiation given off by a heated surface. They are used in applications where direct temperature measurement is not possible.
|
|
Paddlewheel flow meters have a paddle wheel that is perpendicular to the flow path. The rotor axis is positioned to limit contact between the paddles and the flowing media.
|
|
Peristaltic pumps use rotating rollers pressed against special flexible tubing to create a pressurized flow.
|
|
pH and oxidation reduction potential (ORP) instruments measure or monitor pH (relative concentration of hydrogen ions [H+] in a solution) as well as ORP.
|
|
Piston pumps and plunger pumps are reciprocating pumps that use a plunger or piston to move media through a cylindrical chamber. The plunger or piston is actuated by a steam powered, pneumatic, hydraulic, or electric drive. Piston pumps and plunger pumps are also called well service pumps, high pressure pumps, or high viscosity pumps.
|
|
Positive displacement pumps use a mechanical force such as gears, bladders, pistons, plungers or diaphragms to push liquid through and out of the pump.
|
|
Pressure sensors include all sensors, transducers and elements that produce an electrical signal proportional to pressure or changes in pressure.
|
|
Radio frequency identification (RFID) products read or write data to RF tags that are present in a radio frequency field projected from RF reading/writing equipment.
|
|
Refractometers measure the critical angle of refraction through a sample. The critical angle of refraction will change with concentration.
|
|
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.
|
|
Single board computers (SBC) serve as the motherboard for instrumentation systems including modern PCs. SBCs are composed of a microprocessor, memory chip, and serial and parallel interfaces to communicate with other devices.
|
|
Telemetry receivers and telemetry transmitters are data acquisition components used to gather information from remote locations via wireless communication.
|
|
Temperature indicating products include labels, paints, crayons, or other markers that change color or shape when exposed to a certain temperature. Temperature indicating products are typically non-reversible and are designed for one-time use.
|
|
Temperature indicators and temperature instruments are designed for temperature monitoring and analysis. These devices either come equipped with an integral sensor, or require sensor input.
|
|
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.
|
|
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.
|
|
Viscometers define viscous properties of a fluid at ambient or defined temperatures.
