Details
Q1: What is the explosion-proof grade of this ultrasonic level sensor?
A1: The explosion-proof grade of this ultrasonic level sensor is Exd IIC T6 Gb. It uses a flameproof enclosure design and is suitable for hazardous areas containing explosive gases, providing safe and reliable non-contact level measurement for industrial applications.
Q2: What is the difference between a standard ultrasonic level transmitter and an explosion-proof ultrasonic level transmitter?
A2: A standard ultrasonic level transmitter is used in normal industrial environments, while an explosion-proof ultrasonic level transmitter is designed for hazardous areas with explosion risks. The explosion-proof model adds certified protection, such as Exd IIC T6 Gb, making it suitable for chemical, oil, gas, and other hazardous applications.
Q3: What is the dead zone of an explosion-proof ultrasonic level meter?
A3: The dead zone of an explosion-proof ultrasonic level meter is the area close to the sensor where measurement is not reliable. This model has a 0.3–0.5m dead zone depending on the sensor model, so the installation height should keep the liquid surface outside this range for accurate level measurement.
Tips: What causes an explosion-proof ultrasonic level sensor to lose signal?
An explosion-proof ultrasonic level sensor may lose signal due to foam, vapor, turbulence, incorrect installation, blocked signal paths, or power supply problems. Proper installation, suitable measurement conditions, and regular inspection help maintain stable ultrasonic level measurement.
