Electropneumatic Regulator

TESCOM’s ER5000 regulator features a microprocessor-based PID (proportional, integral, derivative) controller that provides precise algorithmic pressure control. The ER5000 can be used on its own to control the pressure of natural gas or inert gases from 0 to 100 psig (0-6.9 bar). The device can also be connected to any pneumatically-actuated regulator. When paired with a regulator, the ER5000 offers pressure control for gases and liquids from vacuum up to 30,000 psig (2,068 bar). The ER5000 provides for true closed-loop control with exceptional accuracy and response time.

Versatile Pressure Regulation Capabilities

The TESCOM ER5000 can be controlled using any PC with a direct USB or RS485 connection. The device also accommodates analog setpoint signals from 4-20 mA, 1-5V, or 0-10V analog sources. It can be wired to accept multiple I/O configurations, as well as daisychaining of up to 32 controllers using the same RS485 network.

ER5000 regulators sense pressure using internal sensors or external transducers placed within the actual process line. These units can be operated 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.”

TESCOM’s ERTune™ software (included) provides a user-friendly interface through which the device’s performance can be customized by tuning the proportional, integral, and derivative values.

The ER5000 electropneumatic regulator installs quickly and provides dependability, flexibility, and high precision performance in any industry or application.
