Electro-pneumatic pressure regulators

Characteristics for Camozzi's Digital Electro-pneumatic Regulator Series ER include its compact design in combination with the user-friendly digital display and keypads from which it is possible to read and set all relevant parameters such as zero/span adjustment, operation mode, error code, etc.

The series comes in two sizes: size 1 which has a flow rate of 400 L/min; and size 2 with 1500 L/min. The control pressure range is 0-5 bar and 0.5-9 bar. Control signals are 0-5, 0-10 V, 4-20 mA.

In addition, it comes in a version with digital inputs (10 bits) in case no analog signal is available. Connection of input/output is through a simple Sub-D connector.

Another important function available on the series (on the analog input version) is the preset memory function, which enables the user to switch the regulator between eight preset pressure values via three outlets only (3 bits). In this mode no analog signal from the control unit is required, which in some cases can contribute to reduced costs for the user.

The series is provided with either an analog or digital output which can be used for external monitoring and is furthermore equipped with an extra error output signal which indicates if an error has occurred in the regulator.

The unit is environmentally friendly, with no lead or polyvinylchloride, and has an automatic power-off feature to conserve energy on the digital display.

The series is useful for many applications, including: air turbine control, air motor control, tension and grinding force control and fluid discharge rate control.
