analog vacuum gauge / with controller

Controlled pressures and processes guarantee high reproducibility and
recovery yields in distillation processes. Furthermore controlled processing
leads to significantly lower operation costs and less environmental damage.
Measuring sensor and electromagnetic ventilation valve can externally be
mounted as complete building group. They belong to the scope of supply of the
controller.
The connecting cable can be implemented in different lengths, max. 5 m.

The vacuum control box VCB 521 is available in four types to allow for control
of different vacuum sources.

VCB 521 cv:
with pressure control over control valve integrated at the box

VCB 521 ef:
with pressure control over a analog output for the control of an external
speed adjusted vacuum pump (ecoflex)

VCB 521 en:
with pressure control of an external vacuum pump by on/off circuit of the
motor (economic)

VCB 521 es:
with external sensor and ventilation valve for the regulation of the vacuum
over a optional control valve or over a analog output for the control of an
external speed adjusted vacuum pump (ecoflex) or an external vacuum pump by
on/off circuit of the motor (economic).
