TESCOM ER5000 Electronic Regulators
TESCOM regulators are electropneumatic pressure regulators that maintain the pressure set point in gas delivery systems, regardless of output fluctuations. These pneumatic regulators, also called pressure-reducing valves, are used when precise pressure control has a critical effect on an outcome. They allow for the automated, centralized control of pressure for production machinery, test benches or any application requiring multiple set points or system defaults, even if the location of the regulator is inaccessible.
The TESCOM ER5000 is an electronic gas pressure regulator that can be used as a standalone device to control pressure for inert gases from 0 to 100 psig (0-6.9 bar). TESCOM Electronic regulators can also be connected to any dome/air loader air actuated regulator for pressure control for gases and liquids from vacuum up to 30,000 psig (2,068 bar).
It features a microprocessor-based PID controller (Proportional, Integral, Derivative) that provides precise algorithmic pressure control. The ER5000 electronic pressure regulator allows for true closed-loop control, with exceptional accuracy and response time.
How Does an Electronic Gas Pressure Regulator Work?
ER5000 electropneumatic pressure regulators sense pressure using internal sensors or external transducers placed within the actual process line. These sensors monitor output pressure and adjust the timing of internal servo valves to maintain the pressure set-point.
Using command signals, the regulator is able to detect the need for more pressure, triggering a shift in a regulator valve that exposes the outlet to more incoming pressure. If lower pressure is needed, the valve shifts again to decrease the incoming pressure.
These units operate in one of three control modes: internal feedback (using only the internal sensor); external feedback (using only the external source); or cascade, which uses internal and external sources to create a “loop within a loop.” This double-loop capability allows TESCOM electronic regulators to manage higher flow rates at their outlets than would be possible with single-stage control.
