ZOC33
Section 2: Introduction
The ZOC33 is an electronic pressure scanner which can
accept up to 128 pneumac inputs. Each ZOC33 module
incorporates 64 individual piezoresisve pressure sensors.
Each eight pressure sensors are manufactured in a housing
designed to facilitate eld replacement. No special tools
are required to access the sensors. The ZOC33 electronic
pressure scanning module is specically designed for use in
wind tunnels, ight tests or applicaons where space is at a
premium and pressures will not exceed 50 psi.
The ZOC33 is powered by ±15Vdc. The module is manu-
factured in a 64 channel model, a 128 channel duplexed
model and a 64 channel valveless model. All models are
available in mulplexed versions only.
The ZOC33 pressure sensors are arranged in blocks of 8.
In all variaons except the valveless model, each block of
eight sensors has its own individual calibraon valve. This
valve had four modes of operaons:
(1) Operate
(2) Calibrate
(3) Purge
(4) Isolate
The modes are selected by applying control pressures in
a predetermined and logical order. The ZOC33 calibraon
valves ulizes valve logic where the valve defaults to the
purge mode when no control pressures are applied.
Beginning with serial number 144, all ZOC33 modules have
a 500 ohm planum RTD installed. This RTD is used by a
DSM3000/3200/3400 module or RAD3200/4000 module
to determine the temperature of the ZOC33 module. This
feature will be added to any older ZOC33 module received
for repairs.
Beginning with serial number 390, all ZOC33 modules have
a TEDS ID chip installed and programmed to interface with
a RAD3200/4000 or DSM3400 pressure measuring system.
This feature will be added to all older ZOC33 modules
received for repair.
Beginning with serial number 399, the ZOC33 valves were
redesigned. This results in a small change to the module
dimensions. This change only applies to valved models. A
ZOC33 valved model that requires repairs to the valves will
have to be upgraded to the newest conguraon.

ZOC33 Section 2: Introduction
This module contains sixty four (64) pressure sensors in
eight sensor packs. Each sensor pack contains:
• eight sensors
• a calibraon valve
• an excitaon board
• a high speed mulplexer
The output of each sensor is directed to the mulplexer/
amplier. The channel to be output is selected by a CMOS
level binary address supplied by either a Scanivalve data
acquision system or by the customer’s data acquision
system.

Section 2: Introduction
This module contains sixty four (64) pressure sensors in
eight sensor packs. Each sensor pack contains:
• eight sensors
• a calibraon valve
• a duplexing valve
• an excitaon board
• a high speed mulplexer
• 16 input tubes (Bank A and Bank B, 8 inputs each)
The sensors are arranged in eight groups of eight. Each
sensor has two pneumac inputs: Bank A and Bank B. The
inputs are switched pneumacally by enabling the duplex-
ing valve. Even though there are 128 pressure inputs only
one Bank of 64 pressure inputs can be measured at one
me. Each group of eight sensors may be a dierent range.
The standard output of the module is ±2.5Vdc correspond-
ing to the channel selected by a CMOS level 6 bit binary
address.

earlier.

later.
