Series 3300 Float Operated Level Controls for internal mounting.
Designed for external mounting on the tank, the 2200 series models feature a float chamber that is fully welded, offering extreme simplicity
and low construction cost.
The standard model comes with 1" NPT process connections; 1" SW connections are also available, to which 1", 1½”"and 2" flanges can be applied in the configurations and face-to-face dimensions shown below. In the standard model the chamber is made of carbon steel, while the internal elements are in AISI 316 stainless steel, the float is in AISI 316 L and the attraction sleeve is in AISI 446.
All the models in this series can be fitted with one or more type 1, 2 or 3 switch mechanisms (up to 3 SPDT or 2 DPDT), or with a single type 4 or 5 mechanism.
All the models are factory set to the differential minimum (about 20 mm for a specific gravity of controlled liquid equal to 1 kg/dm³): this level can be increased in range only for devices fitted with type 1, 2, or 3 switch mechanisms, respectively by 50 mm if fitted with a single mechanism, and 25 mm if fitted with two mechanisms; it remains set to the minimum if the device is fitted with 3 mechanisms.
Sensing units with special dimensions can be provided for applications requiring particular distances between the switching levels.
