A/1K-2W-O-EH - 1000 Ohms @ 32 degrees F ( platinum RTD sensing element) with a 0.00385 temperature coefficient. The standard outside air configuration is based on a European style enclosure that locks out moisture with a gasketed cover and watertight fitting. They are designed to be mounted flush to an exterior wall.

A/1K-2W-O-SUN - The ACI Sun Shield is a reliable solution for protecting temperature and relative humidity sensors. It consists of nine molded plastic plates which provide maximum airflow around the sensor while at the same time minimizing direct exposure to sunlight. The passive shield is shaped to allow natural air convection around the sensor so that the air temperature inside the shield is a good representation of the outside air. The shield also provides protection from rain and snow. The ACI SUN SHIELD is covered by ACI's Five (5) Year Limited Warrant which is located in the front of ACI's Sensors & Transmitters catalog or can be found on ACI's web sit which is www.workaci.com.

A/1K-2W-PBS - ACI's Low-Profile "Button" Sensor is designed to be aesthetically pleasing for higher profile applications. It's small size and appearance make it a perfect choice for applications where temperature sensors should blend into the background. Options include bras stainless stee or plastic for installation flexibility. Low profile blends into environment aesthetically. Available in Plastic Brass and Stainless Steel. Mounting Accessories include Etched Teflon lead wire Paintable

A/1K-2W-PM - The Pipe Mount probe is specially designed to fit pipe contours of 1? diameter or less.  The unique shape of the probe allows for a strap to securely install the sensor to against a pipe.  In addition the convex contour aids in the temperature transfer allowing for a more accurate signal.
