CZ900 online condition-monitoring system

CZ900 combines sensors, acquisition hardware and analysis software for rotating-equipment condition monitoring. Wired vibration, vibration/temperature, speed and eddy-current displacement sensors connect through acquisition hardware. Wireless sensors communicate through gateways, with wired or cellular backhaul described for delivery to the server.

CZ900Server provides instrument settings, asset configuration, data monitoring, analysis, basic settings and system administration. CZ900Sample communicates with field hardware, acquires data, performs secondary alarm processing and stores data. The source lists support for YD260, YD360, wireless gateways, YD285 and 8/16/32-channel acquisition devices.

The introduction mentions SMS/email alarms, predictive diagnosis and maintenance recommendations as system functions. It does not supply messaging setup steps or validate delivery in a particular installation. The home dashboard presents statistical data.

This introduction describes YD30 as a micromachined silicon sensor and YD30W as a piezoelectric sensor with a PT100 temperature element.

For YD30, the independent manual states 0–2 kHz, while the product reference gives 0–10 kHz with a different tolerance, IP68 and 2000 g. For YD30W, the independent manual states 0–2 kHz rather than this source's 0–10 kHz. Confirm the supplied sensors' calibration and versions. The YD30W marking here is Ex ia IIBT4 Ga.

YD260 is described here as a single-axis vibration/temperature sensor with an STM32L4 processor. It acquires 24,576 acceleration samples per second for envelope processing and derives a 2048-point acceleration record for further processing. YD360 is described with an ADXL35X triaxial device, STM32L4 processor and 2048 16-bit samples per second. Its routine report includes battery voltage, temperature, one selected vibration quantity and diagnostic result.

The YD360 description wakes every 30 seconds to collect data and immediately sends data on reaching an enabled alarm threshold; otherwise it reports at the configured interval. Average consumption entries are printed as ≤500 uAH for YD260 and ≤400 uAH for YD360. Their unit is not silently converted to a current rating.

These are different descriptions from YD260 V1.50 and both standalone YD360 sources. Do not combine the 2024 ranges, dimensions or battery claims with those manuals.

YD62 is described as a magnetoresistive rectangular-pulse sensor. This source lists 0–20 kHz pulse frequency, 5–26 V DC supply, −40 to +120 °C operation, at least 1 kΩ load, at most 47 Ω output impedance, 20 mA maximum load current and at most 10 mA consumption excluding the load. Sensing distance is 1–4 mm for A3/electrical steel or 5–10 mm for magnetic steel with consistent polarity. The module entry is m ≥ 1; protection is IP68. Vibration/shock ratings are 30 g at 10 Hz–2 kHz and 100 g. High-level voltage and explosion-marking typography remain ambiguous as in the YD62 manual.

The YD9800 table lists a probe temperature of −50 to +175 °C and driver temperature of −50 to +120 °C, with ≤0.05%/°C drift. Its narrative instead starts the probe range at −40 °C. These values also differ from the independent YD9800 manual.

YD9800 response here is 0–10 kHz, with −1% amplitude / −1° phase at 1 kHz and −5% amplitude / −100° phase at 10 kHz. Interchangeability error is ≤5%, resolution 0.05%, protection IP68 and housing stainless steel. The output table places both −18 to −24 V DC and +18 to +30 V DC supplies under a negative-voltage heading and lists −2 to −18 V and optional 1–5 V outputs. The supply/output association is not clear enough to prescribe wiring; confirm the actual variant.

YD510 is a DIN-rail module for concentrated measurement points, typically in a control-room cabinet. The source describes variants with eight vibration channels plus one speed channel, or eight process channels. Communication is 100 Mbit/s Ethernet with two RS485 interfaces.

Direct velocity/displacement ranges depend on the selected sensor. The independent YD510 manual states a 0.5 Hz lower primary-signal limit and contains conflicting dimensions; confirm hardware applicability rather than selecting a preferred figure.

The LoRa gateway supports 60 sensors, a maximum 150 m line-of-sight distance and firmware updates. Its interfaces are two RS232 ports, one reserved RS485 port and one Ethernet port for server communication. Both RS232 ports use 57,600 baud: the left port is for firmware updates; the middle port is for debugging and basic configuration.

For indoor use, the source specifies a 12 V adapter. For the described solar arrangement, an 18 V panel connects to the terminal labeled 24 V, and the terminal labeled 12 V becomes a battery connection/output. These roles depend on power mode; confirm the exact gateway drawing and battery arrangement before making connections.

SYS flashes once per second. LORA1 is the data channel and LORA2 the control channel; each indicator toggles when data is received. The gateway is specified for −25 to 60 °C and at most 85% RH, with dimensions 190 × 46 × 114 mm and average consumption no greater than 1 W.

System configuration organizes company, plant/site, equipment, measurement point and measurement item information. Accurate association lets the user locate vibration data for a particular area and machine.

Real-time data displays the latest vibration measurements. A variable-speed machine requires an installed speed sensor to show measured real-time speed. History can be filtered by date for a selected measurement item and exported. Trend analysis displays one item's vibration changes over a chosen period.

Vibration Analysis includes waveform, spectrum, envelope spectrum, cepstrum and shaft-orbit views. The illustrated functions also include low/high-frequency filtering, harmonic markers and sidebands. For a multi-point time-domain comparison, open Analysis and Diagnosis → Vibration Analysis, select several measurement items and then select a timestamp. The source does not define every calculation or available combination of sensor types.

For waveform data:

1. Open Analysis and Diagnosis → Vibration Analysis.
2. Select a measurement item and a timestamp.
3. Choose the waveform view.
4. Open Waveform Data and select Export.

For spectrum data, follow the same selection sequence, choose the spectrum view, open Spectrum Data and select Export. The source does not specify an export file format in this workflow.

The introduction lists early-fault identification, fault-type and location prediction, and maintenance recommendations. Examples include wear, internal cracks, misalignment, excessive shaft bending, loose connections, pump cavitation and centrifugal-fan surge. These are described capabilities; this document supplies neither diagnostic acceptance criteria nor a guarantee that a particular machine fault will be detected.
