Chart recorders and strip charts are data acquisition tools used to generate a plot, graph or other visualization of data versus time.
|
|
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 acquisition systems and instruments collect, digitize and process multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes.
|
|
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.
|
|
Dial thermometers are bimetal or bi-metallic, liquid or gas-filled, and vapor-tension-based. These devices display temperatures in Fahrenheit, Celsius, or both.
|
|
Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display.
|
|
Distributed and supervisory control systems (DCS / SCADA) are system architectures for process control applications.
|
|
Humidity measurement instruments test for absolute humidity, relative humidity, or dew point in air.
|
|
Ion selective electrodes measure the potential of a specific ion in solution. This potential is measured against a stable reference electrode of constant potential.
|
|
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.
|
|
Oscilloscopes translate an electronic signal into a pattern or waveform on a screen. As it is traced across the screen, the waveform creates a signature of the signal's characteristics.
|
|
pH electrodes and oxygen reduction potential (ORP) electrodes measure the voltage across a circuit formed by the measuring metal half-cell and the reference half-cell.
|
|
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.
|
|
Thermocouple elements are temperature sensors that are useful over a wide range of temperatures. Thermocouples are formed by two dissimilar metals.
