Omega Engineering PX821-005DV, Wet/Wet Differential Pressure Transducer. The OMEGA ® PX821 Series is a high accuracy, lightweight, wet/wet differential pressure transducer. For compatibility with a number of different liquid and gaseous media, both the positive and negative pressure ports are manufactured from Hastelloy C276 and 316L stainless steel. In addition, its rugged, all welded construction assures excellent resistance to shock, vibration and overload. 0-5 psid. Brand new in original box.
MKS Pressure Controller Model 640A. Range is 50 psi. The MKS Instruments 640 Absolute 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 640 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 640, with LED status indicators, for use as simple on/off process limits. Brand new in sealed bag. Part # 640A-21646
