9 Environmental Stability

If the sensor is used in equipment or machinery, make sure that the sensor used for measurement and the sensor

used for reference sense the same temperature and humidity. If the sensor is placed in the equipment, the

response time will be prolonged, so ensure that sufficient measurement time is reserved in the program design.

The sensor is based on Austrian Song temperature and humidity sensor corporate standards are tested. The

performance of the sensor under other test conditions is not guaranteed and cannot be used as a part of the

sensor's performance. Especially for specific occasions required by users, no promises are made.

9.1 Tracking Information

All sensors have laser labels on their surfaces. See Figure 20.

Figure 20. Sensor laser marking.

The label on the carton is shown in Figure 15, and provides other tracking information.

A label is also attached to the tape, as shown in Figure 21, and other trace information is provided.

Figure 21. Label on the tape.

9.2 Transport packaging

Sensor is packaged in tape and reel, sealed in an antistatic ESD bag. The standard packaging size is 5000 sheets

per roll. For sensor packaging, the 440mm (Approximately 55 sensor capacity) and the front 200mm

(Approximately 30 sensor capacity) part of each reel is empty.

The packaging diagram with sensor positioning is shown in Figure 22. The reel is placed in an anti-static pocket
