250E Gas Inlet Pressure/Flow Control Module
With the 250E Gas Inlet Pressure/Flow Control Module, input can be supplied by a Baratron® for closed-loop pressure control, or flow input can be measured by a mass flow meter for closed-loop flow control.
Process control can be manually adjusted through a front panel potentiometer or remotely programmed with a 0 to 5 VDC analog signal for profile generating. With the multi-set point option a simple ground closure will select one of four preset set points. The basic 250 provides a simple analog error meter to show deviation of actual versus desired set point. It is also available with an optional 4½ digit LED display which provides a readout of the input transducer signal and eliminates the need for a separate display instrument.
