|
|
Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions.
|
|
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.
|
|
DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies.
|
|
Disinfectors treat water to inactivate, destroy, and/or remove pathogenic bacteria, viruses, protozoa, and other parasites. Common methods include chlorination and alternative disinfectants.
|
|
Distributed and supervisory control systems (DCS / SCADA) are system architectures for process control applications.
|
|
Distributed control systems (DCS) use decentralized elements or subsystems to control distributed processes or complete manufacturing systems.
|
|
Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other.
|
|
Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.
|
|
Flow switches are devices that monitor flow and send a trip signal to other devices, like a pump, for protection. These switches can be used for the measurement of gases, liquids, and steam.
|
|
Gas samplers, liquid samplers and solids samplers are used to take samples of media from process streams, reactors or storage vessels.
|
|
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.
|
|
Level switches is a generic search form for devices that are used to detect liquid or powder levels, or interfaces between liquids. These level measurements are indicated via an electrical switching action.
|
|
Liquid level sensors are used to detect liquid levels or interfaces between liquids such as oil and water or liquids and solids.
|
|
Motor speed controllers are electronic devices that control motor speed. They carry specifications for drive type, product classification, electrical ratings, and operating parameters.
|
|
Motor starters and contactors are motor-starting devices. They combine a contactor with overload protection and are designed for starting AC or DC motors.
|
|
Network equipment is used to split, switch, boost, or direct packets of information along a network. This product area includes network hubs, switches, routers, bridges, gateways, multiplexers, transceivers and firewalls. Often, network equipment is defined by is protocol or port type (e.g., Ethernet switch, USB hub).
|
|
Network routers are protocol-dependent devices that connect subnetworks. They are also used to break down a large network into smaller subnetworks.
|
|
Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the switches decide where incoming packets are transferred to, based on the NIC's 48-bit address.
|
|
Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.
|
|
Pressure transmitters translate the low level output of a sensor or transducer to a higher level signal suitable for transmission to a site where it can be further processed. These devices include pressure sensors, transducers, elements, and instruments.
|
|
Pump controllers monitor flow and/or level variables, and control a pump accordingly to maintain the desired levels. Pump control can include simply turning a pump on and off, or more advanced controls for pump speed, output pressure, etc.
|
|
Single phase uninterruptible power supplies (UPS) sit between an AC outlet and an electronic device to provide power conditioning, back-up protection, and distribution for electronic equipment loads. They also prevent power disturbances from affecting the performance and life of the electronic device and vital data.
|
|
Supervisory control and data acquisition (SCADA) systems are large-scale, industrial control and measurement systems that consist of a central host, one or more remote units, a communications network, and specialized software.
|
|
Overload relays prevent an electric motor from drawing too much current and overheating; includes thermal and solid state overload types.
|
|
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.
|
|
Uninterruptible power supplies (UPS) are backup batteries that provide emergency power to electrical systems in case power becomes unavailable. They are connected between a power source (such as an electrical outlet) and the equipment to protect (such as a motor or computer).
|
|
Volumetric gas flow switches are devices with a switch output used for measuring the flow or quantity of a moving gas in terms of a unit of volume per unit time, such as cubic feet per minute.
|
|
Volumetric liquid flow switches measure the flow or quantity of a moving fluid in terms of a unit of volume per time, such as liters per minute. These flow sensing devices have a switch output.
|
