Available in aspiration and impact configurations. Both are supplied in a wide range of standard and custom lengths. An aspiration (static) probe has a straight-cut tip that opens parallel with the air stream. An impact (total pressure) probe has an angle-cut tip that opens directly into the air stream: it is positioned so that it faces into the air stream for pressure applications and away from it for vacuum applications. Either type of probe can be supplied with a straight slip-on connector or a tri-barbed connector.
Series RFS-4000 is a line of general purpose proving switches designed for HVAC and Energy Management applications. These switches can be used to sense positive, negative, or differential air pressure. The plated housing encloses a diaphragm, a snap-acting switch, and an optional calibration spring (in adjustable set point models). The sample line connections located on each side of the diaphragm accept rigid or flexible tubing. Various electrical connections are available. An optional enclosure cover can be provided to protect the operator from accidental contact with the live switch contacts. The enclosure cover has five knockouts for a 1⁄2″ conduit connection

Series DNS2 Air Flow Pressure Sensing Switches are the best solution for applications that require dual set points. In addition, DNS2 switches have a narrow switching differential, and low set point tolerance over a wide operating temperature and set point range. Factory-calibrated and sealed set points are available from 0.05′′ to 10.0′′ wc. DNS2TM switches can be used to sense positive, negative or differential air pressure. Typically, DNS2 switches are applied to two-stage furnaces where high fire and low fire set points are required. Each of the two glass-filled polycarbonate housings contains a sensing diaphragm and an integral snap-acting switch. One or two sample line connectors are located on either or both sides of the diaphragm to accept air sample connections. The snap action switch can be actuated by a pressure or vacuum air flow, or by a pressure or vacuum differential.
