Blind Zone: The gauge has a blind zone ranging from 0.35 - 0.5m. This is due to the design of the ultrasonic transducer and the signal processing circuit, which is carefully calibrated to ensure reliable performance even in the presence of a small blind zone.
Measurement Accuracy: The measurement accuracy is 0.5%FS. This means that across the entire 20m measurement range, the maximum error in measuring the level difference is only 0.1m (0.5% of 20m). Such high - precision measurement is crucial for applications where even a small deviation in level difference can have significant consequences.
Sound Beam Angle: The sound beam angle is ±8°. This narrow beam angle allows for precise targeting of the measurement area, minimizing the impact of external factors such as reflections from nearby objects and enhancing the accuracy of the level difference measurement.
Working Humidity: The TSL300CJ can operate efficiently within a humidity range of 0 - 60%. The instrument is designed with moisture - resistant materials and coatings to protect its internal components from the harmful effects of humidity, ensuring stable performance in both dry and humid environments.
Working Temperature: It functions reliably across a temperature spectrum of - 20 - 65°C. The gauge uses temperature - compensated components and advanced thermal management techniques to maintain accurate performance in different temperature conditions. In cold environments, heating elements can be activated to keep the components within the optimal operating temperature range, while in hot environments, heat - dissipating materials and cooling fins help to dissipate excess heat.
Resolution: With a resolution of 0.001m, the TSL300CJ can detect even the most minute changes in the level difference. This high resolution is achieved through the use of high - precision analog - to - digital converters and advanced signal processing algorithms, making it suitable for applications that require extremely precise level difference measurement.
Protection Level: The protection level of the TSL300CJ is IP67. The enclosure of the instrument is made of high - quality, waterproof and dust - proof materials, and all the seams and openings are carefully sealed. This ensures that the instrument can be used in harsh environments, such as in areas with water splashing or dusty conditions, without being damaged by water or dust ingress.
