Overview
Overview
The 641B11TS1V42V Gauge Pressure Controller features 10 Torr full scale pressure measurement, a 10,000 sccm valve orifice, and 0.25 in. male tube fittings. It has a Viton seal and a Viton valve plug. This gauge pressure controller is a self-contained, compact, closed-loop electronic control system used for upstream or downstream pressure control. It contains a Baratron® Capacitance Manometer, normally-closed proportioning control valve, and closed-loop control electronics. Electrically similar to a standard MFC, the 641B Gage Pressure Controller for Closed-Loop Electronic Pressure Control is powered by ±15 VDC at only 200 mA, permitting use with standard power supply/display electronics. The pressure output and input control signals are linear 0-5 or 0-10 VDC, user-selectable. Two trip points are included in the 641B, with LED status indicators, for use as simple on/off process limits.
