ZOC22B Multi-Channel Module

Analog multi-channel module designed to measure gas pressures

About the Multi-Channel Module ZOC22B

The Model ZOC22b electronic pressure scanning module is extremely compact and accepts up to 32 pneumatic inputs and converts them to high level electronic signals. Each ZOC22b module incorporates 32 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 ZOC22’s 32 sensors to service up to 128 input pressures.The ZOC22 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.

Two ZOC22 versions are available:
ZOC22b/32Px – 32 Px inputs each with its own dedicated sensors.
ZOC22b/32PxX2 – 64 Px inputs duplexed* between 32 sensors.
