Vane Operated Flow Switches-2

In many industrial processes that use a low pressure flow of air within ducting or similar housing, it isnecessary to safeguard personnel and to prevent damage to equipment which may be caused by the sudden failure of the air supply. The M2 Series Air Flow Failure Switch is suitable for connecting either directly to the main switch-gear controls or to an alarm warning system so that the necessary safety measures may be takenautomatically or manually at the instant that failure of the air supply occurs.The M2 instrument is primarily a sensitive on/off device, suitable for use on most systems where...
