Pressure-Sensing Switches and Probes PRESSURE-SENSING SWITCHES Sense positive, negative, or differential air pressure. Negative pressure rating same as positive. Mount with diaphragm in a vertical plane. For residential, light commercial mid-efficiency furnaces, and direct digital control (DDC) applications. No. 2E462 includes ferrules, one 12" length of 1⁄4" O.D. flexible tubing, and 1⁄4" O.D. tubing nuts. Gold Contact—For computer environments, direct digital control, or where low-ampere currents are wired. Pneumatic Signal Output—For applications requiring a pneumatic output signal for actuation, or in an intrinsically safe environment where electrical arcing must be avoided.

STATIC AND TOTAL PRESSURE PROBES

Static Pressure—Passive probes sense pressure as air flow aspirates across the probe tip opening.

Total Pressure—Impact probes sense negative or positive pressure, depending on the angle of the probe tip opening.
