High pressure gas exhaust - depending on pressure range.
** Optional vacuum system kit, allows the -ve port gas to be directly discharged to atmosphere, by-
passing the vacuum pump.
†
Optimum controller transient response and minimum time to set-point may be degraded if either the
pneumatic supply or vacuum system has restricted flow. Installing a reservoir volume, which has
larger capacity than the load volume, located in close proximity to the controller supply ports can
improve the controller response.
‡
Optional negative gauge pressure generator kit, allows the -ve port to directly discharge to
atmosphere, by-passing the negative gauge pressure generator.
To protect the control module (item 8), for ranges above 100 bar, from over-pressure a suitable
protection device (such as a relief valve or bursting disc) must be fitted to limit the applied supply
pressure to below the MWP.
Optional differential connection kit.
