LFS72 Explosion-proof Air Speed Transmitter is suitable for gas flow measurement in Explosion-proof environments. This Explosion-proof Air Velcoity Transmitter can convert the flow rate of gas into an electrical signal and transmit it to the control system, The range can be adjusted on-site through buttons, and the lP65 protection grade casing is used. lt is suitable for energy management systems, VAV and fan control, environmental pollution control, smoke hood control, oven and boiler ventilation control and other fields.
Features
* High-precision MEMS micro-pressure core, high precision and wide operating temperature range
* Clear LCD digital display
* Zero button available on-site, wind speed range adjustable
* Strong stability and long service life
* IP65 protection grade housing
