The explosion-proof air velocity transmitter can convert the flow rate of gas into an electrical signal and transmit it to the control system. The wind speed range can be adjusted using the zero point button on site.

Features

Explosion-proof wind speed transmitter adopts a high-precision MEMS micro-pressure core, high precision and wide operating temperature range.
The air velocity transmitter is equipped with an LCD digital display, which has a clear display and is convenient for real-time monitoring of wind speed data.
The wind speed transmitter provides an on-site zero point button and an adjustable wind speed range to meet different application requirements.
The explosion-proof duct air velocity transmitter has strong stability, long service life, and reduces maintenance costs.
It uses an IP65 protection grade housing and has good dust and water resistance.

Note: Wiring wire diameter D must meet: 7mm≤D≤12mm

Installation

Applications

Tips: Maintenance of the explosion-proof wind speed transmitter

Use a dry or slightly damp soft cloth to wipe to prevent dust and oil from affecting the performance of the equipment.
Ensure that the wiring terminals are firm to avoid looseness or oxidation that causes unstable signal transmission.
Regularly clean dust or foreign matter on the sensor probe to ensure measurement accuracy.
If measurement deviation is found, the on-site zero button can be used for adjustment to ensure accurate data.
Regularly check the integrity of the housing to ensure that the explosion-proof performance is not damaged and to ensure safe operation.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
