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.
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.
Process controllers take a signal from a temperature device, such as a thermocouple or RTD, or from a pressure/flow/level sensor, and maintain a setpoint using an output signal (relay, voltage pulse, current, or linear voltage depending on model). Various controllers are available that support modes such as PID, ON/OFF, Ramp/Soak and Manual.
ProSense digital panel meters are available in 1/32 DIN and 1/8 DIN meter sizes with simple menu-driven pushbutton configuration.
Low-cost graphical panel meters with versatile programmable features and user-configurable alarms provide critical power or process data at a glance.
Trumeter hour meters and counters provide reliable counting and run hours tracking metered from processes, equipment or machinery. These units are available in a variety of input voltage ranges and mounting options.
Temperature switches, sensors, transmitters, thermowells and thermocouples provide accurate temperature monitoring and control.
ProSense pressure switches and pressure sensors monitor system pressure in hydraulic and pneumatic applications and vacuum systems.
Pressure gauges and thermometers display process readings for pneumatic, hydraulic, HVAC, plumbing, industrial and commercial applications.
Level sensors monitor the level of liquids, pellets, powders, and other similar products in tanks and process systems. Available are:
ProSense flow measurement devices monitor liquid media and provide reliable flow indication (display), detection (switch output) or measurement (analog output).
Signal conditioners convert process, temperature and other electrical signals into voltage or current signals for use with PLCs, loop controllers, encoders, digital displays or any application requiring an isolated or analog signal.
Electro-pneumatic transducers (I/P) are electro-pneumatic regulators that control air pressure based on an analog input signal. NITRA transducers convert a 4-20 mA current signal (I) from a PLC or other controller to a linear pneumatic output pressure(P).
HydroMode food grade potable water regulators are compact units that provide economical, high-performance pressure regulation of drinkable water.
Pipeline valves allow ON/OFF control and/or mixing and diverting of process media such as air, oil, inert gas, water and even some caustic materials.
