Flame Ionization sensors for monitoring total hydrocarbon levels SNR650 digital system for continuous emission monitoring

The remarkable Model 650 FID from Control Instruments is the first total hydrocarbon analyzer that solves all of the sampling, measuring and reporting problems found in industrial applications. Designed and manufactured specifically for industrial use, the Model 650 is the ideal choice for process and stack monitoring of a wide range of emission sources, including catalytic and thermal oxidizers, solvent recovery systems, engines, power plants, waste incinerators, and others.

Mounts directly onto the process ductwork

The Model 650 is unique because the complete system mounts directly to the process wall or ductwork, at the sample pickup point. The entire sensor assembly is fully heated —up to 200°C—and the sample probe runs from the sensor directly into the process. The result? Response time improves, line clogging due to sample vapor condensation is eliminated, and maintenance is greatly reduced.

Flow Control Assures Accurate Readings

Sample delivery is a critical factor in obtaining accurate readings, however, many FIDs suffer from reading errors caused by mechanical pump fluctuations.

The Model 650 does not use a pump, but instead draws the sample using an aspirator driven by compressed air. It employs proportional pressure control to guarantee constant sample flow and pressure through the cell, assuring you the highest level of accuracy in your final readings.

Low Maintenance and Outstanding Access

The Model 650's extremely efficient operation greatly reduces maintenance and down-time—two critical concerns when running any emission monitoring system.

When you do service the unit, all parts are easy to access, and filters are easy to replace, even when the unit is still hot.

Alarm Relays

The Model 650 also includes a complete set of integral alarm relays—for Warning, Danger, Malfunction and Horn—so that relay action is initiated directly by the sensor, without relying on an intermediary connection.

Automatic Calibration

The Model 650 has solenoid valves for both Zero and Span test gas. Calibration checks can be made manually—or you can program calibration checks to run automatically, at any time of day or night.

Complete Access—from Anywhere in the World

The Model 650's built-in push button control panel allows the operator to access calibration and diagnostics routines right at the sensor. But you don't have to be at the analyzer to know its status or make adjustments. In fact, there are three great ways to access the Model 650 remotely. The unit has a built-in 4-20mA analog output that can tie into your PLC or a simple display meter. Or you can add Control Instruments' remote display and control monitor for complete bi-directional access.

And if you need a monitoring system with true digital communication—either now or in the future—the Model 650 provides a Modbus compatible RS-485 serial port. Optional remote access is also available.

Add the Model 650's software to any computer, and use the easy-to-read Windows-type screens to observe readings and sensor status, run system diagnostics, make adjustments, and change settings.

You can easily tie the Model 650 into your PLC, plant-wide data acquisition system or process control system. Or tie into any PC or laptop. And don't forget that the 650's modem capability allows you complete access from any-where in the world.
