Introduction
There are three pressure stations in the PV 62XG / PV 62X - IS series. Two pneumatic pressure
stations to give you accurate and controlled pressure and vacuum conditions, PV 621 and
PV 622. One hydraulic pressure station to give you accurate and controlled hydraulic pressure
conditions, PV 623.
To give the connected equipment overpressure protection, there are pressure relief valves (PRV)
available for all the pressure stations. Refer to Chapter 6.
When used with a DPI 620G / DPI 620G - IS multi-function calibrator, HART® / FOUNDATION™
Fieldbus / Profibus® communicator, together with a PM 620 / PM 620 - IS / PM 620T / PM 620T - IS
pressure module, the following functions are available.
•
Measure pressure / Leak test.
•
*
Documenting software.
•
*
HART® (Highway Addressable Remote Transducer) communications software to set up
and calibrate devices that use the HART® field communications protocol.
•
*
Foundation Fieldbus™ communicator.
ATEX, IECEx and ETL approved intrinsically safe versions are available for use in hazardous
areas.
Summary of Functions
This list gives a summary of the available pressure station functions:
•
“Quick fit” pressure adaptors for easy connection to the equipment under test.
• Volume adjuster to give accurate control of applied pressure.
• Pressure connection for a PM 620 / PM 620 - IS / PM 620T / PM 620T - IS pressure module.
• Latch mechanism to connect the DPI 620G / DPI 620G - IS calibrator to make a fully
integrated pressure calibrator instrument.
• Optional pressure relief valves (PRV) to give overpressure protection.
Pneumatic Pressure Stations
The following list are functions available with the PV 621G / PV 622G / PV 621 - IS / PV 622 - IS:
• Selector switch to change the pump operation from pressure generator to vacuum
generator.
• Needle point pressure release valve to control the release of pressure.
Hydraulic Pressure Station
The following list are functions available with the PV 623G / PV 623 - IS:
• Internal hydraulic reservoir: 100 cm
3
(6.1 in
3
)
• Self sealing pressure module connection to prevent fluid leaks.
• Fast thermal stability for devices connected directly to the test port connection, less than one
minute.
* Optional extra.
