Back to Options.
Devices concerned: DGPT2 & DGP.
With the 2GD option, the bulb holder tube has two magnetic bulbs, like with the 2G option, but the switching thresholds are offset and not simultaneous. The device has 15 output terminals.
Part references:- Complete bulb: PL515

With the 2GD option, there is a high threshold (12 to 15 mm [.3” to .38”] from the top of the large float’s tank) that can be used as an alarm and a low threshold (3 to 5 mm [.08” to .13”] from the bottom) that can be used as a trigger.
