About this part
ATM-390B2907-NO is a Granville-Phillips Series 390 Micro-Ion ATM modular vacuum gauge. Micro-Ion and Granville-Phillips are trademarks of Brooks Automation, and the vacuum-measurement product line is now supported by MKS Instruments. The 390 module combines a Micro-Ion ionization gauge with a Conductron heat-loss sensor and Piezo diaphragm sensors to measure absolute pressure continuously from high vacuum to atmosphere. The archived unit is a no-display configuration. The exact output/interface, setpoint-relay, filament, and fitting options follow from the full Series 390 catalog number and the device label
Configurations vary. Verify the exact unit before choosing a replacement.
