Pump cycling by monitoring discharge pressure presents many challenges. Surges can cause false trips. High cycle rates can strain pumps and sensors. Suspended solids can foul sensor orifices. The One Series electronic pressure switch, shown mounted on an isolator ring, provides programmable surge filtering, solid-state construction and Plug Port detection, making the One Series ideal for wastewater plants. Fully adjustable set points and deadbands eliminate the need for loop controllers.
