Description
The Dwyer Instruments A-306-A Outdoor Thermostatic Pressure Sensor is designed to measure static air pressure in outdoor environments and transmit readings to connected control parts. It includes a 50-foot tube and mounting hardware, allowing flexible installation for pressure sensing across ducts and equipment. Within HVAC systems, it monitors pressure differences across filters, coils, and blowers to support airflow balance and system diagnostics. Commonly used with manometers, pressure switches, and controllers, this sensor works as an essential element in maintaining accurate pressure measurement and stable system operation.
