3.5 Chassis Assembly
The chassis assembly is the housing for the system. The transducers are self-contained inside the chas-
sis and can be replaced using basic hand tools. Figure 3.5 shows the top view of the chassis with the
cover removed.

3.5.1 Control Module
The control module is referred to as the “Solenoid Valve Regulator” (SVR Module). The SVR Module is
available in four variations depending on the working pressure range:
• Low Pressure SVR Module (LPSVR)
• Medium Pressure SVR Module (MPSVR)
• High Pressure SVR Module (HPSVR)
• Extra High Pressure SVR Module (EPSVR)
Pressure limits for all of these are specified in Section 4, Specifications.
Each control module includes platforms for up to two high performance pressure transducers, CPR4000,
which are traceable to NIST standards. Both of these transducers can be used in conjunction with the
highly stable pressure regulator to produce a precise output. Each transducer includes its own on-board
compensation and calibration data so that any transducer can be replaced in the instrument without
requiring a recalibration.
