Dwyer Instruments 1910-10 Pressure Switch 340155-7026 Ensure the 120Vac supply is

Ensure the 120Vac supply is stable and install a fine mesh strainer upstream if the media contains particulates

you mitigate the risk of intermittent power disturbances damaging sensitive internal windings

while the 120V configuration allows straightforward field replacement without electrical modification

The probe relies on a solid electrical ground through the boiler casting to complete the sensing circuit

This permanent split capacitor motor typically requires a 10 MFD / 370V run capacitor (not included) to ensure proper starting torque and 1080 RPM efficiency

Dwyer Instruments 1910-10 Pressure Switch 340155-7026 Ensure the 120Vac supply isThe Dwyer Instruments 1910 10 is a field proven low differential pressure switch engineered for high precision monitoring of air and non combustible gases in demanding HVAC applications. This compact Series 1900 component features a versatile SPDT switch, providing reliable control or alarm signaling for systems requiring set points between 3. 0" w. c. and 11. 75" w. c. Built for the job site, the 1910 10 utilizes a clear to access internal set point
