Aspirator Panels with Flow Switch*

Single or dual sensor system is designed to monitor gas atmospheres from extreme conditions with either temperature, moisture, or pressure challenges. A powerful air aspirator can pull a sample from up to 100 feet away. The filtered and conditioned sample gas is then passed across one or two different detectors. Each detector shares a common calibration and compressed air inlet for aspirated flow. This system is fault tolerant removing the need for expensive downtime and maintenance. The sample is diluted with air after the gas sensor and then returned to a common exhaust reducing the danger of potential hazardous gases entering a safe work space.

System integrity is maintained at all times using a flow fail monitoring device which provides a NO contact that activates if the sample line becomes blocked or damaged or if the air supply is removed or interrupted.

The panel can be used with direct-connect (sensors connected to an RKI controller), or with S2 Series, and M2 Series transmitters. All transmitters have a 4-20 mA signal for direct connection to the site DCS, PLC or site control system. If needed, RKI instruments can supply a dedicated Gas Detection Control system to provide local alarms, 4-20 mA output with a wide range of dry contacts, making the system very sophisticated and user friendly.

Integral sample filter included to remove water and dirt, automatic drain type.

RS485 Modbus output options available on the M2 transmitter.


Select desired detector assembly M2A, Direct Connect, or S2 heads as separate line items.
