Analog panel meters measure and display processes and electrical variables with a simple dial display.
|
|
Analog resistance meters are instruments that measure electrical resistance. They display values on a dial, usually with a needle or moving pointer.
|
|
Analog voltmeters are instruments that measure voltage or voltage drop in a circuit. They display values on a dial, usually with a needle or moving pointer.
|
|
Clamp meters are ammeters that can measure current without the need to disconnect the wires where the measurement occurs. They provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends.
|
|
Current transformers are used to step down current in a very predictable fashion with respect to current and phase. They are generally used as inputs to current instruments.
|
|
Digital multimeters (or multi-meters) are used to measure electrical quantities such as voltage, current, resistance, frequency, temperature, capacitance, and time period measurements.
|
|
Digital panel meters measure and display processes and electrical variables via an alphanumeric digital readout.
|
|
Digital resistance meters are instruments that measure electrical resistance. They use solid-state components and display values digitally.
|
|
Electrical current sensors measure AC and/or DC current levels. They receive current inputs and provide outputs as analog voltage signals, analog current levels, switches, or audible signals.
|
|
Electronic counters and electronic timers are completely electronic units for performing a variety of counter or timer functions.
|
|
Instrument transformers are used to step-down current or voltage to measurable values. They provide standardized, useable levels of current or voltage in a variety of power monitoring and measurement applications.
|
|
Power meters and wattmeters are used for high-accuracy measurements of power over a wide-frequency bandwidth, and from both AC and DC circuits.
|
|
Sound level meters and noise dosimeters are used in sound and noise analysis. Applications include industrial safety, traffic noise studies, and scientific noise measurement.
|
|
Tachometers are used to measure the velocity of a rotating object. They operate on the principle that a driven motor (i.e., a motor operated as a generator) produces a voltage that is proportional to the angular velocity of the motor shaft.

|
Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level.
|
|
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.
|
|
RTD temperature probes convert the RTD resistance measurement to a current signal, eliminating the problems inherent in RTD signal transmission via lead resistance.
|
|
Thermocouple elements are temperature sensors that are useful over a wide range of temperatures. Thermocouples are formed by two dissimilar metals.
|
|
Thermocouple temperature probes are bimetallic style probes used for various temperature sensing applications.
|
|
Universal process controllers constitute a broad area of control devices that may be employed in the monitoring and control of many different process variables, including temperature, pressure, flow and other values.
