Dust-resistant flow sensors

Omron Electronic Components LLC has released the D6F-P MEMS flow sensor that incorporates a double cyclone patented dust segregation system (DSS). It delivers accurate results in real-world dusty environments that include HVAC/VAV (heating ventilation air conditioning/variable air volume) by keeping particulate away from the sensing chip.

Omron Electronic Components LLC has released the D6F-P MEMS flow sensor that incorporates a double cyclone patented dust segregation system (DSS). It delivers accurate results in real-world dusty environments that include HVAC/VAV (heating ventilation air conditioning/variable air volume) by keeping particulate away from the sensing chip. The sensor delivers an amplified, temperature-compensated output signal with high accuracy and repeatability, even at very low flow rates, according to the company. Accuracy is critical in sophisticated zone temperature control systems where a proper intake of fresh air is required to avoid a “sick building” situation. A compact 17 x 22 mm footprint and PCB terminals allow for direct connection to the board of damper control modules. www.omron.com Omron Electronic Components
