PRODUCT DATA SHEET Edwards nAIM series Digital Active Inverted Magnetron vacuum gauges combine the gauge-head and controller in one compact active unit. These are new digital versions of gauges that have proved to be rugged and reliable in a wide range of applications ranging from scientific instruments to industrial processes. The nAIM gauges feature compact size for easy installation, a serial output and a replaceable sensor tube. They are also CSA and C/US approved as well as fully RoHS compliant due to their lead-free construction. Features and benefits • Wide-range supply voltage allows operation from 15 to 48 V DC • Gauge naming allows user to store gauge identification data • Rapid tube replacement without pre-calibration • Unique striker design ensures rapid striking even at high vacuum or in contaminating conditions • Low external magnetic field version (L) for sensitive analytical instruments available upon request • Serial communications based on a simple ASCII, low latency, query and command protocol that can operated in a point to point or multi-drop system with minimum overhead • Adjustable open collector set-point output for straightforward process control and interlocking • CSA and C/US approved, meets the safety requirements for electrical equipment for measurement • RS485 or RS232 versions • 9600 to 38400 baud, 8bits, 1 start bit, 1 stop bit, no parity nAIM DIGITAL ACTIVE INVERTED MAGNETRON VACUUM GAUGE
