Honeywell SP970A1013 Manual Or Minimum Position Switch 5PSI Span

The Honeywell SP970A1013 Manual Or Minimum Position Switch used to detect and regulate the airflow of HVAC equipment. It works by detecting changes in pressure within the air and within a range of 5 PSI. When the air pressure goes below a certain value, the switch is turned on, and sends a control signal. This signal can then be used to trigger corrective activities, the openness of a damper to enhance the airflow or to call the maintenance staff. It is fit to be used with the operating temperature between 0°F and 140°F and humidity between 5% and 95% RH. It has low airflow usage of 0.022 SCFM, to ensure minimal energy consumption is used.
