The ZOC23b 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. Contact Scanivalve if you wish to use the ZOC23b with Scanivalve’s model ERAD4000
(Remote A/D) or DSM4000
(Digital Service Module) Pressure Measurement System. The ERAD4000
convert the ZOC23b’s analog output to temperature compensated Engineering units, and then output that data Ethernet TCP/IP or UDP. Typical ZOC23b applications include pressure measurement on wind tunnel tests, wind engineering tests, wind turbine validation tests, inside flaps or control surfaces in flight tests. and other space constrained spaces. When the ZOC23b 8 channel remote modules are ordered less the valving, it is ideal for measuring pressures on rotating equipment.
The Model ZOC23b is similar to Scanivalve’s ZOC22 32 channel pressure scanner. The pressure sensor and calibration valves have been divided into 4 remote modules, each containing 8 pressure sensors. The 4 remote pressure sensor modules are connected with electrical umbilicals which connect into the ZOC23b amplifier multiplexer unit. Each module has its own reference pressure, calibration tubulations, and calibration valving. This allows the remote pressure sensor modules to be different pressure ranges. An integral “duplexing” valve is available to allow the ZOC23B’s 32 sensors to service up to 64 input pressures. This calibration valve allows the ZOC sensors to be automatically calibrated while on-line or pressure inputs to be purged.
Three versions are available:
ZOC23B/32Px – 32 Px inputs each with its own dedicated sensors
ZOC23B/32PxX2 – 64 Px inputs duplexed between 32 sensors.
ZOC23B/8Px – Muxless, Valveless (No calibration valve)
