About the HVAC-211
Advanced Sensors HVAC 211 Series Transmitter incorporates a rugged silicon MEMS pressure sensor that is designed to measure ultra-low differential pressures in a wall mounted package. The two wire 4-20mA loop output is ideal for locations where the supply voltage can fluctuate. A single LED identifies proper operation.
The HVAC 211 has front side pressure ports and simple screw terminal for electrical connections making fast and easy installations for the HVAC professional.
The wall mounted package can be fastened using 4 screws in any orientation since the MEMS sensing element has minimal position sensitivity.
