Safety Notices 3
Beamex® POC8 Automatic Pressure Controller
Warnings and Caution Notices
HIGH PRESSURE! High pressure gases are potentially hazardous. Energy
stored in these gases and liquids can be released suddenly and with ex-
treme force. High pressure systems should be assembled and operated only
by personnel who have been trained in proper safety practices.
NOT EXPLOSION PROOF! Installation of this instrument in an area requiring
devices rated as intrinsically safe is not recommended.
POSSIBLE INJURY! The tubing, valves, and other apparatus attached to the
gauge must be adequate for the maximum pressure which will be applied,
otherwise physical injury to the operator or bystanders is possible.
USE THE PROPER PRESSURE MEDIUM! Use only clean, dry, non-corrosive gases.
This instrument is not designed for oxygen use.
HIGH SOUND LEVELS! Pressures from 70 bar / 1000 psi and up can generate
sound levels above 80dbA for brief period when they are exhausted directly
to atmosphere. A muffler/ snubber is installed in the vent port. Removal of
muffler/ snubber will allow for sound levels to exceed 80dbA.
As with most sensitive electronic equipment, switch the power switch off
before connecting or disconnecting to a power source to prevent data loss.

Chassis Assembly
The chassis assembly is the housing for the system. The pressure measurement modules are
self-contained inside the chassis and can be replaced using basic hand tools. The picture below
shows the top view of the chassis with the cover removed.
Chassis assembly.
The heart of the chassis assembly is referred to as the “Controller Unit”. They are available in
three variations depending on the working pressure range:
-1 to 10 barg / -15 to 150 psig
-1 to 100 barg / -15 to 1 500 psig
-1 to 210 barg / -15 to 3 045 psig
Each chassis includes platforms for up to two high performance pressure measurement mod-
ules, which are traceable to international standards. Both of these modules can be used in con-
junction with the highly stable controller unit to produce a precise output. Each measurement
module includes its own on-board compensation and calibration data so that any module can be
replaced in the instrument without requiring a recalibration.
