Modular Solutions 

Mini-Convectron modules can measure from 10-3 to atmosphere in a compact, space-saving package. The Convectron ATM module eliminates the need for two sensors in those applications that require low pressure measurement and an accurate indication of differential pressure at atmosphere, such as vacuum system loadlocks. 
The Micro-Ion module combines the world's smallest ionization gauge with electronics in a compact package. 

The Micro-Ion Plus combination gauge module operates over a broad range of measurement from high vacuum to atmosphere. It incorporates state-of-the-art heat-loss technology with the Micro-Ion gauge. This broad-range gauge modules delivers a full set of features previously found only in rack-mounted controllers. 
The Stabil-Ion gauge module provides the stability and reliability of the Stabil-Ion gauge in a modular package. 

Modules Include: 

275 Mini-Convectron 
354 Micro-Ion® 
347 Stabil-Ion® 
385 Convectron ATM 
356 Micro-Ion® Plus
392 Micro-Ion® Plus Modules
390 Micro-Ion® ATM Modules 

Rack Mount Solutions

Rack mount vacuum electronic systems that operate ion gauges, heat-loss sensors, and thermocouples provide a range of features that can be configured specifically to your process needs. 

A variety of communication protocols are available including analog, RS-232, RS-485, and DeviceNet™ all designed to integrate into your control scheme quickly and easily. Many controllers provide local displays and a choice of setpoints that deliver simplified control system integration. 

Solutions Include

370 Stabil-Ion Gauge Controller 
375 Convectron Gauge Controller 
350 Bayard-Alpert UHV Gauge Controller 
358 Micro-Ion Gauge Controller
