GSESCH0016 is the replacement pressure transducer for the Tornatech GPX electric fire pump controller, with a 0–600 PSI sensing range and drawing identification PT1. In a GPX panel, this sensor supplies the water-pressure signal the controller monitors to start the fire pump at its set cut-in pressure.
A failing transducer often announces itself as a displayed pressure that no longer tracks a gauge on the same sensing line, starts that occur with no real pressure drop, or a controller that never registers cut-in pressure at all. Swapping the unit is straightforward: relieve pressure on the sensing line, remove the old transducer, and install the replacement before re-pressurizing and verifying the reading.
This part is matched to the Tornatech GPX; for JPLT jockey pump controllers and other Tornatech panels, see our GSEDAN0003 transducer listing. Cybertronic Controls is veteran-owned and based in Hammond, Louisiana — call 985-351-5681 and we will verify the correct PT1 transducer for your controller before it ships.
