External Light Box
To report the status of varying sensor(s) to a remote location a light(s) are installed in an external box, which the customer installs in a location on their tool or in the clean room close to the tool.

External Box with Magnahelic Gauge
To report the status of the differential pressure of the filter, and to aid in understanding when the filter will need to be changed, a magnahelic gauge is displayed in an external box, which the customer installs in a location on their tool or in the clean room close to the tool.

A Magnahelic Gauge Can be Installed in a Flush Mount External Box
To report the status of the differential pressure of the filter, and to aid in understanding when the filter will need to be changed, a magnahelic gauge is displayed on an external panel, which the customer installs flush mounted in a location on their tool or in the clean room close to the tool.

9-pin Connector to Carry the Signal From Various Sensors
To report status of the varying sensor(s) a 9-pin D-sub connector may be added at a customer specified location on the plenum that carries the status of the sensors. The customer then provides a mating connector to receive the signal.
