Explosion-Proof Air Velocity Transmitter with Adjustable Range & LCD Display

The Explosion-Proof Air Velocity Transmitter is an intelligent sensor designed for gas flow measurement in hazardous or explosion-risk environments. It converts gas velocity into an electrical signal and transmits it to a control or monitoring system, providing precise, stable, and long-term reliable readings.

Equipped with a high-precision MEMS micro-pressure sensing core, this transmitter offers fast response, wide operating temperature range, and excellent stability. The IP65-rated explosion-proof housing ensures durability and safety in harsh or contaminated environments such as boiler rooms, air ducts, industrial ventilation, and pollution control systems.

Users can easily adjust the measurement range and perform zero calibration on-site using the built-in control buttons. A clear LCD digital display provides real-time airflow readings, making configuration and monitoring simple and intuitive.

Ideal for energy management, VAV systems, clean rooms, and exhaust monitoring, this device ensures safe and accurate gas flow measurement in compliance with industrial safety standards.
