4 – HIGH PRESSURE CONTROL UNIT
Mensor offers a means to measure and control
pressure in the ranges above 1000, up to 6000 psi
with an accuracy of 0.025% of full scale (0.01%
optional for most ranges). This high pressure ca-
pability is accomplished with the Mensor Model
410 High Pressure Control Unit (HPCU). The HPCU
is a companion chassis that interfaces with a host
PCS 400
as shown below to provide virtually seam-
less operation over the full range of the combined
instruments. When connected together the routing
of the signals and pressure activity between the two
units is automatic. All commands are entered
either from the
PCS 400
keypad, or over the remote
bus to the host. The HPCU front panel includes four
status LEDs for visual feedback of its current state
while the more detailed data is returned to the
PCS
400 display and/or the remote bus. A separate
User’s Manual, part number 0014564001, is sup-
plied with the HPCU. Contact Mensor for additional
information and specifications for the Model 410
HPCU.
5 – TI/HEISE/MENSOR MODEL 179 CON-
TROLLER EMULATION
The
PCS 400
can be configured to respond to most
Model DPC 179E Pressure Controller commands
over the GPIB and RS-232 remote buses. Contact
Mensor for additional information (Manual Sup-
plement part number T407).
6 – VACUUM GAUGE AND TUBE
A Hasting’s VT-6 Vacuum Gauge and DV6M Gauge
Tube are available. This option is particularly help-
ful when measuring vacuum pressure with a
PCS
400
. With this option the DV6M Gauge Tube is
plumbed into the
PCS 400
as close to the pressure
transducers as is practical. The gauge tube is wired
to a five pin connector (Amphenol #126-216)
mounted on the rear panel. The Hastings VT-6
vacuum gauge connects to this rear panel connec-
tor with an Amphenol #126-223 mating connector.
The rear panel connector location is illustrated in
figure 8.6, and the wiring is shown in figure 8.7.
Using the Hasting’s VT-6 Vacuum Gauge
With the vacuum gauge OFF, adjust the meter
pointer to the dot at the right hand end of the scale.
With the vacuum gauge ON and connected to the
rear panel of a
PCS 400
which is vented to atmos-
phere, the meter pointer will read ‘ATM’. Then,
with a vacuum applied to either the REFERENCE
port of a gauge type
PCS 400 , or to the MEAS-
URE/CONTROL port of an absolute type instru-
ment, the meter pointer will move to indicate the
vacuum pressure. Refer to the Hastings’s manual
for further instructions.

CAUTION: DO NOT APPLY MORE
THAN THE MANUFACTURERS
RECOMMENDED MAXIMUM
PRESSURE TO THE VACUUM
GAUGE TUBE OR IT MAY EXPLODE!
The maximum pressure for the Hasting's gauge tubes
provided by Mensor is 50 psia. But, energizing the
gauge tube at pressures above atmosphere (15-50 psia)
will decrease the life and accuracy of the tube.
