Instruments supplied with an intrinsically safe sensor are generally preferred over explosion proof equipment because there is not enough power present to create an ignition source.  Illinois Instruments offers a moisture analyzer with an intrinsically safe sensor that is remote-mounted in a hazardous area.  The Series 400 Moisture Analyzers offer the option of using a remote intrinsically safe sensor while the electronic components are mounted in a safe area.

The Series 400 Moisture Analyzers with a remote intrinsically safe sensor have a measuring range of -90oC to +20oC in most industrial gases.  Cabling can be provided for the intrinsically safe sensor in length up to 200 meters.

Illinois Instruments' Series 400 Intrinsically Safe Sensor represents our latest advancement in moisture analysis. This series was designed to be customized to your application while providing a simple, yet affordable analyzer.  The Series 400 Intrinsically Safe Sensor incorporates our high quality aluminum oxide moisture sensor. This sensor provides accurate, dependable results over a wide range from –110°C to +20°C. The aluminum oxide sensor is maintenance-free and is the popular choice for the most demanding applications.

All models feature microprocessor control for stable and repeatable operation. A bright, autoranging LED display provides direct measurement output. User-adjustable alarms, scaleable analog output signals, RS232 interfacing, and process sample bypass flow systems are all optionally available.

Three different configurations add to the base Model 410 (shown at right) to offer the choices needed to satisfy virtually all industrial environment and operational constraints.
 

Model 410 can be used on the bench or Panel Mounted.	Model 420 is NEMA 4X / IP66 rated for weatherproof and waterproof locations.	Model 430 houses one or two analyzers in its 4U (19 inch) rack mount cabinet.
