Drum
Level Transmitter
Model #: 11C and 11CH
The Drum Level Transmitter sense the differential pressure between a constant head and the pressure developed by the amount of water in the boiler drum, and transmits a linear pneumatic signal which is porportional to this differential pressure to the other control components for system reference. The only defference between the two working models is the use of different components in the measuring unit portion of the assembly to allow for different working pressures. The model 11CH operated with a working pressure up to 1000 psig, and the model 11 CH operates with a working pressure up to 2500 psig.
