EPR Series – High-Precision Electronic Pressure Regulator with Digital & Analog Control

In demanding industrial environments where precision and responsiveness are essential, the EPR Series Electronic Pressure Regulator stands out as a compact and intelligent solution. Designed for converting analog or digital electrical signals into proportional pneumatic pressure, this closed-loop regulator ensures unmatched accuracy and control—without requiring complex setups or special tools.

Engineered with an integrated 8-bit microcontroller, the EPR Series easily interfaces with external systems via analog, current, voltage, built-in keypad, or RS-232 serial input. This eliminates the need for expensive and complex pressure control systems of the past. By using pulse width modulation (PWM), the regulator converts the electrical signal to a stable pressure output, continuously maintained with the help of an onboard pressure sensor providing real-time feedback.

Field adjustments are quick and hassle-free. Whether with or without a built-in keypad or protective metal shroud, the EPR Series remains unaffected by vibrations and ensures no air consumption during steady-state operation—enhancing energy efficiency.

With a compact design of just 120 x 70 x 40 mm, this IP65-rated unit is ideal for installations where space is limited, but precision is non-negotiable.
