Process Control and Measurement
Continuously changing variable data and control methods are often required in process control. Process variables such as pressure, flow, level, and temperature are sensed, transmitted, and converted for continuous or batch processing by a wide variety of instrumentation.

Process Control & Measurement
Process control and measurement devices monitor variables such as pressure, flow, level, and temperature, providing signals to represent changing values or discrete (ON/OFF) outputs to indicate conditions such as limit thresholds or alarms. These signals enable monitoring and control, triggering actions in valves, actuators, or other devices to maintain optimal process conditions.
- Pressure sensing devices measure pressure at a specific point in a process and may be used for monitoring or paired with a control device to perform functions such as opening or closing a valve to regulate 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.
- Humidity sensors provide accurate, real-time data about moisture levels, allowing for the control and maintenance of optimal conditions across various environments.
- Vibration detection devices are used to monitor, analyze, and identify vibrations of industrial equipment, which may indicate a malfunction, pending failure, or process restriction.
- Weight / force sensors, like load cells, provide reliable measurement of compression, bending, and tension forces and are vital for weighing applications.
- Other devices used for process control systems include displays for monitoring process values, signal conditioners, and process valves.
