ESMUS10F1 Explosion-proof split-type ultrasonic level meter with 4-20ma/rs485

The split-type ultrasonic sensor is based on the principle of ultrasonic reflection. The main unit sends a driving signal to the probe, and the piezoelectric ceramic transducer in the probe converts the electrical signal into high-frequency ultrasound and emits it vertically. The ultrasound reflects off the liquid surface, and the probe receives the echo and converts it back into an electrical signal to send to the main unit. The main unit calculates the liquid level height based on the speed of sound and the time difference.

1.Explosion-proof safety: Equipped with excellent explosion-proof performance, it can operate safely and reliably in flammable and explosive environments such as petroleum, chemical, and pharmaceutical industries.
2.Strong environmental adaptability: The probe can be placed in harsh working conditions while the main unit remains away from the site, avoiding the effects of high temperature, corrosion, and humidity. Some probes can withstand higher temperatures and are made of corrosion-resistant materials.
3.Convenient installation and maintenance: The split design allows flexible installation without entering the container. During maintenance, only the main unit needs servicing, reducing maintenance difficulty and risk.
4.Accurate measurement: Using advanced ultrasonic technology, it offers high measurement accuracy. Some products have an error range of less than 0.5% and feature automatic temperature compensation to eliminate the impact of temperature on measurement results.
5. Diverse signal output: Typically integrated with signal output options such as 4-20mA analog and RS485 digital, it can be adapted to PLC and DCS systems for remote monitoring.
