The ZOC33 is designed to measure gas pressures only. It has an analog output of +/- 0-2.5Vdc, or optionally +/-0-5Vdc to operate with customers' in-house data system or Scanivalve's model ERAD4000 (Remote A/D) or DSM4000 (Digital Service Module) Pressure Measurement System. The ERAD4000 and DSM4000 convert the ZOC33's analog output to temperature compensated Engineering units, and then output that data Ethernet TCP/IP or UDP.
Typical ZOC33 applications include pressure measurement on wind tunnel tests, wind engineering tests, wind turbine validation tests, and flight tests. An optional ZOCTCU Thermal Control Unit is available for use in flight tests or other extreme temperature testing. The ZOCTCU allows the ZOC33 to operate in an environment down to -45 deg C.
The Model ZOC33 electronic pressure scanning module is extremely compact and accepts up to 64 pneumatic inputs and converts them to high level electronic signals. Each ZOC33 module incorporates 64 individual silicon pressure sensors, calibration valving, a high speed multiplexer (45kHz), and an instrumentation amplifier. An integral "duplexing" valve is optionally available to allow the ZOC33's 64 sensors to service up to 128 input pressures.
The ZOC33 module also incorporates a calibration valve that allows the ZOC sensors to be automatically calibrated on-line as well as purge the input lines of contaminants or condensation.
Three ZOC33 versions are available:
ZOC33/64Px - 64 Px inputs each with its own dedicated sensors.
ZOC33/64PxX2 - 128 Px inputs duplexed between 64 sensors
ZOC33/64Px - Valveless (no calibration valve)
