ITT Barton Model 199 Differential Pressure Unit Simple Type: Differential Pressure Unit

The Barton Model 199 Differential Pressure Unit (DPU) actuates the recorders. The DPU is a dual bellows assembly enclosed within pressure housings. The bellows are liquid filled and withstand overranges equal to the working pressure of the housing without calibration change. Movement of the bellows is transmitted through a torque tube from the DPU to the recording mechanism. The torque tube is hermetically sealed to eliminate friction and leakage; it does not require lubrication.
