Adhesive dispensing equipment is used for the controlled dispensation of adhesives and/or silicones. These devices include manual dispensing caulk guns, hot melt glue guns, and an assortment of mix / meter and dispensing systems.
|
|
Batch controllers maintain the correct size of a discrete batch of process material, such as the volume of a liquid. They are often interfaced with sensors such as load cells, or with volumetric flow meters.
|
|
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 I/O modules or cards have both input and output functionality. Digital or discrete I/O modules include on-off signals used in communication, user interface, or control.
|
|
Digital-to-analog converters (DAC) transform a digital number into a corresponding analog voltage or current.
|
|
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 computers, totalizers, and rate indicators integrate the functions of flow and temperature measurement, computation, data acquisition, input / output (I/O) standardization, and closed loop control. They require external sensor inputs and may be used as local rate indicators.
|
|
Flow controllers monitor and maintain proper humidity levels in environmental test applications, or in other areas such as food storage or electronic room regulation.
|
|
Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.
|
|
Flow transmitters provide electrical outputs that are proportional to flow inputs. They use flow meters to measure the flow of liquids and gases.
|
|
Fluid dispensing equipment includes all manner of devices that dispense, mix and dispense, or mix, meter and dispense fluid media.
|
|
Frequency and pulse signal conditioners accept the output of devices that are specifically designed for frequency measurement and convert or condition these signals to digital data or suitable levels for digitization.
|
|
Frequency-to-voltage converters accept a signal and convert its frequency to a corresponding analog voltage level.
|
|
Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage.
|
|
Liquid flow meters are used for measuring the flow or quantity of a moving fluid.
|
|
Volumetric liquid flow switches are devices with a switch output used for measuring the flow or quantity of a moving fluid in terms of a unit of volume per unit time, such as liters per minute.
|
|
A mass flow meter is a device that consist of a mass flow sensor or transducer and signal processing electronics. Fluid (liquid or gas) flow is measured in mass rate units (lbs/min).
|
|
Positive displacement flow meters measure the volume or flow rate of a moving fluid or gas by dividing the media into fixed, metered volumes. These devices consist of a chamber that obstructs the media flow and a rotating or reciprocating mechanism that allows the passage of fixed-volume amounts.
|
|
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).
|
|
Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.
|
|
Signal converters contain inputs for one type of signal and outputs of another. Features can also include filtering and amplification or attenuation.
|
|
Turbidity instruments measure the average volume of light scattering over a defined angular range. Both particle size and concentration of suspended solids as well as dissolved solids can affect the reading.
|
|
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.
|
|
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.
