Current to Pressure Transducers for the Argon & Nitrogen Dewars

PDF Version Also Available for Download.

Description

A current to pressure (I/P) transducer will be used in the D-Zero piping system. The transducer is necessary to precisely control the control valve positioners located at the argon and nitrogen dewars. A 4-20 rnA signal will come from the PLC function of the TI565. This electric signal must be converted by the transducer to a pneumatic signal of 3-15 psi which will position the actuator. By doing this, the valve can be opened or closed to any adjusted amount from the control room or a remote I/P controller. A total of 9 transducers will be used at the dewars. ... continued below

The nitrogen dewar will have 3 that are located outside and will have to be weatherproof. The argon dewar will have 6, located inside, that will have to be explosion proof or intrinsically safe.
