Dwyer Instruments 1823-00 Pressure Switch 321894-709 allowing for a wide range

allowing for a wide range of control inputs including 4-20mA (via 500 Ohm resistor)

it ensures direct mechanical alignment and electrical compatibility within Carrier

Always check the pitch of your fan blades to ensure they are designed to pull air through the coil and exhaust it out the top for proper heat dissipation

providing a high-torque mechanical connection that resists vibration

you can install the Emerson D-48 for standard moisture removal

Dwyer Instruments 1823-00 Pressure Switch 321894-709 allowing for a wide rangeThe Dwyer Instruments 1823 00 Pressure Switch is a industrial grade solution designed for precision monitoring of air and non combustible gases in HVAC systems. Covering a set point range of 0. 07" to 0. 22" w. c., this differential pressure switch is essential for verifying fan status, filter efficiency, and low airflow conditions. It features an approximate deadband of 0. 05", ensuring stable operation without excessive cycling in turbulent
