What can be improved by monitoring bearing rotation inside an environmental chamber?

Previously, the chamber had to be opened for each inspection. This solution allows for measurement and verification without opening the chamber, reducing labor during long-term testing and minimizing temperature fluctuations caused by opening and closing.

How does the system respond during an anomaly?

An alarm signal can be output if the rotation abnormally increases, decreases, or stops. Additionally, logging the history of rotation speeds helps in analyzing the root cause of anomalies.

Rotation Measurement & Anomaly Detection Without Opening the Chamber

Benefits of This Solution

Conventional Method

・Must open the chamber to visually inspect at every check.

・Opening/closing and inspection for long-term tests is labor-intensive.

・Chamber temperature fluctuates every time it is opened.

This Solution

・No need to open the environmental chamber during inspections.

・Allows for at-a-glance confirmation during routine patrols.

・Reduces fluctuations in chamber temperature due to opening/closing.

Bearing Rotation Measurement

Measure multiple samples simultaneously to evaluate performance and variations.

Alarm Settings

Trigger alerts if rotation speed abnormally increases, decreases, or stops.

Log Management

Record the history of rotation speeds to facilitate root-cause analysis during anomalies.

Measurement Instruments & Signal Converters

■ Analog output can be selected from 0-10V, 0-5V, ±10V, ±5V, and 4-20mA (Optional / Specify at the time of order).
Output update rate is as fast as 0.1 ms (SPD). Full-scale values can also be configured.

■ Alarm (alert) signal can be output when the rotation exceeds specified limits (Optional).

■ Supports both rotation speed and totalizer count measurement (Switchable: simultaneous measurement not available).

■ Supports CAN output for measurement data (Optional).

■ Measurement from 0 Hz.

*Please prepare your own rotation detection sensors.

Customization Support (Enclosure Housing)

■ Multiple measurement instruments can be housed together in a single enclosure.

■ Instrument types, quantities, and connector styles can be specified.

■ Calibration and document issuance are also available for housed products.
