Description
Introduction
In addition, the Thermokon AGS55+ LON excels in ease of installation and weather resistance thanks to the USE-S enclosure (IP65). As a result, the measurement remains consistent, even under changing outdoor conditions.
Features
- Passive outdoor Sensor (PT1000) for accurate temperature measurement outdoors, in cold rooms and greenhouses.
- USE-S enclosure made of impact-resistant PC, UV- and weather-resistant; IP65 according to EN 60529.
- External stainless steel sensing probe sleeve (Ø 6 mm, L 25 mm) with fast response behavior.
- Application range: −35..+90 °C; therefore broadly applicable.
- Simple wiring via detachable plug-in terminal and Flextherm M20.
- Accessories: mounting base, mounting clip and sun/rain shield RS150.

FAQ
Is the AGS55+ suitable for outdoor installation without a sun shield?
Yes, thanks to IP65 and UV resistance this is possible; however, by way of example, a sun/rain shield ensures more stable measurements in full sun.
Can I also use the Sensor in cold rooms?
Yes, therefore the AGS55+ is popular in cold stores; compared with standard sensors, it remains reliable at low temperatures.
Which connection options are available?
Passive 2-wire is common; in addition, there are MultiRange variants with 0..10 V/0..5 V (TRV) or 4..20 mA (TRA).
Which accessories do you recommend?
Consider RS150 as a sun/rain shield and a mounting clip; this keeps the measurement consistent and makes maintenance easy.
