TESCOM ER5000 Series Electric Pneumatic Actuators

The TESCOM ER5000 Series electric pneumatic actuators is a microprocessor-based on a PID (Proportional, Integral, Differential) controller that brings accurate algorithmic pressure control for a wide range of applications. It can be used as a standalone unit to control the pressure of inert or natural gas from 0 to 100 PSIG / 0 to 6.9 bar or connected to any pneumatic actuated voltage regulator. When used with a regulator, the TESCOM ER5000 Series electric pneumatic actuators provide vacuum gas and liquid pressure control up to 30,000 PSIG/ 2068 bar.
