Cleveland Controls NS2-0097-00 Air Pressure Switch has an operating range of 0.05" w.c to 10.0" w.c. The switch approval certificates are UL, CUL, CSA, CE, and Australian Gas Assoc.

The Series NS2 Air Flow Pressure Sensing Switches has a glass-filled polycarbonate housing body that offers stability and can hold many sample line connector options.  Sample line connectors are located on either or both sides of the diaphragm to accept air sample connections.  The housing consists of a sensing diaphragm and includes an integral snap-acting switch.  They are designed to be contaminant-free, reliable, sturdy, and provide low cost with high accuracy.  These switches can be used to sense positive, negative, or differential air pressure.  It also offers a narrow switching differential and low set point tolerance over a wide operating temperature and setpoint range.

You can choose different factory calibrated set points which are available from 0.05″ to 10.0″w.c. The ports are color-coded for easy access. The integral snap-acting switch mechanism (patent pending) is available in SPNO, SPNC, and SPDT terminal configurations.
