S PC EXTSEN units connect a Pressure Controller with no internal pressure sensor to an end user supplied external pressure sensor Designed mainly for the vacuum coating industry the PC EXTSEN marries the sensing ability of an existing capacitance manometer or ion gauge with a Alicat s 16 Series electronics package and internal PID algorithm This enables fast and precise control of extreme vacuum conditions in the coating chamber The PC EXTSEN receives a linear analog signal from the external sensor This analog signal corresponds to a full scale range that is specified by the user at the time of order and corresponds to the scale of the external sensor The PC EXTSEN interprets this analog signal as its sensed pressure The PC EXTSEN then utilizes its proportional control valve to control the flow of gas into the chamber allowing for closed loop vacuum control based on the interpreted signal Set point control and PID tuning all happen through the instrument s interface via the buttons on the display or a user selected analog interface 0 5V 0 10V or 4 20mA or through a multidrop RS 232 interface There are two base models of PC EXTSEN controllers the PC EXTSEN D and the PC EXTSEN D ISC The PC EXTSEN D has an 8 pin Mini DIN female electrical connector as its electrical connection to power ground signal input from the external sensor RS 232 transmit and receive as well as analog transmit and receive The PC EXTSEN D also has
