AC motor drives interface controllers to AC motors. They match the control signals (voltage and power levels) as well as the signal type (analog or digital). They also provide power conversion, amplification, and the sequencing of waveform signals.
|
|
AC servomotors are responsive, high-acceleration motors typically constructed as permanent magnet synchronous motors.
|
|
Analog pressure gauges are mechanical devices that include bellows, Bourdon tubes, capsule elements and diaphragm element gauges.
|
|
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.
|
|
CNC controllers are used to control machines and processes. They provide capabilities ranging from simple point-to-point linear control to highly complex algorithms with multiple axes of control. CNC controllers are used to retrofit many types of machine shop equipment.

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 software is designed to collect, record, store, present and analyze data collected from sensors and other digital devices.
|
|
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.
|
|
DC motor drives act as the interface and power supply between a motion controller and a DC motor.
|
|
DC servomotors are generally small and powerful for their size, and easy to control. Common types of DC servomotors include brushless or gear motors.
|
|
Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.
|
|
Human machine interfaces (HMI) are operator interface terminals with which users interact in order to control other devices.
|
|
Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point.
|
|
Linear motors generate force only in the direction of travel. They are capable of extremely high speeds, quick acceleration, and accurate positioning.
|
|
Motion control systems contain matched components such as controllers, motor drives, motors, encoders, user interfaces and software. Components in these systems are optimally matched by the manufacturer.
|
|
Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems.
|
|
Panelboards and switchgear are electrical distribution devices that convert incoming electrical power into several smaller circuits and provide overload protection in the form of fuses or circuit breakers.
|
|
Pressure gauges are used for a variety of industrial and application-specific pressure monitoring applications. Uses include visual monitoring of air and gas pressure for compressors, vacuum equipment, process lines and specialty tank applications such as medical gas cylinders and fire extinguishers.
|
|
Programmable logic controllers (PLCs) are the control hubs for a wide variety of automated systems and processes. They use a wide variety of inputs and outputs and provide network capability.
|
|
Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps. They provide precise positioning and ease of use, especially in low acceleration or static load applications.
|
|
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.
|
|
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.
|
|
Valve positioners compare a control signal to a valve actuator’s position and move the actuator accordingly. They are used with both linear valves and rotary valves.
