EPR
Series
This highly precise, closed loop electronic pressure regulator, converts a digital or analog signal [current, voltage, built-in, keypad or RS 232] into a proportional pneumatic output. This pneumatic output is very accurately maintained at a preset pressure. There may be a variation of 1% of downstream set pressure. One of the key attributes of this controller is that no special tools are needed to make field adjustments.
The built-in 8-bit microcontroller interfaces easily with other control/monitoring system, thus eliminating expensive systems that were required for this kind of control in the past. As with all Matrix products, the EPR’s are guaranteed a minimum life of 500 million cycles. The microcontroller converts the electrical signal to a proportional pressure output using PWM [pulse width modulation]. An integrated pressure sensor helps monitor and maintain the required set pressure by sending constant feedback when there is a change in desired pressure.
