Different from discrete (ON/OFF) control, process control and measurement devices sense changing values over a set range (ex. 4 to 20mA) that are transmitted during continuous (flow production) or batch (a set quantity or output) processing. Some of the most common variables used for process control are pressure, flow, level, and temperature.
- Pressure sensing devices measure pressure at a specific point in the process and transmit the measured value to a control device that may perform functions such as opening/closing a valve to regulate the pressure.
- Flow sensing devices measure the flow rate (volume per unit of time) and/or consumption (total flow) of liquid traveling through a system.
- Level sensors monitor the level of liquids, pellets, powders, and other similar products in tanks and process systems.
- Temperature switches integrate sensing and a setpoint-tripped output; transmitters receive the measured variable from a sensor (or have an integral sensor) and convert it to an output more typically compatible with industrial monitoring or control devices; controllers combine sensing and control of the variable in one unit.
- Vibration detection devices are used to monitor, analyze, and identify vibrations of industrial equipment, which may indicate a malfunction, pending failure, or process restriction.
- Other devices used for process control systems include displays for monitoring process values, signal conditioners, and process valves.
Temperature / Process Controllers
Process controllers take a signal from a temperature device, such as a thermocouple, RTD, or a pressure/flow/level sensor, and maintain a setpoint using a relay, voltage pulse, current, or linear voltage output (depending on model). Various controllers are available that support modes such as PID, ON/OFF, Ramp/Soak and Manual.
