OUTSIDE AIR
Weatherproof Outside Air Transmitters
The ACI Transmitter Outside Air Series features a two-wire, 4 to 20 mA loop powered output
with optional 3-Wire voltage output signals available. These units are designed to be mounted
out of direct sunlight on the North side of a building or under an eave or intake hood. The
Ruggedized epoxy coated transmitters “-POT” option should be used in extreme environments
or in applications where you are looking for improved accuracy and reduced thermal drift due
to the thermally conductive epoxy and more consistent board temperatures. Zero and Span
adjustments are available for recalibration in the eld when using NIST Certied equipment. All
units include a Weather Proof or NEMA/IP rated enclosure and 1/2” knockouts or ½” NPT
threaded hubs for use during installation. We recommend the use of 18 to 22 AWG shielded
cable for all temperature transmitter installations to protect against the introduction of noise
onto the signal lines. ACI does oer recalibration services for any transmitters sent back to us for a nominal fee.
Applications: Outside Air Temperature Sensing, Economizer Control, Cold Storage Facilities or Warehouses, High Moisture Environments
