Outdoor Temperature Transmitter Basic 4-20 mA

Our rugged and reliable outdoor temperature transmitter is an ideal choice for outdoor areas that require a compact, shockproof and easy-to-install temperature monitoring solution. Thanks to its fixed Pt1000 RTD sensor, temperature is measured accurately. With its standardized 4-20 mA output, it integrates seamlessly with existing heating systems and control systems. It is characterized by its high measurement accuracy and long-term service life, even under difficult operating conditions. The integrated alarm functions, including sensor break, sensor short-circuit and measuring range monitoring, ensure correct temperature measurement and transmission and provide additional safety.The transmitter can be parameterized quickly and easily using DIP switches.

Outdoor transmitter - Mounting
Thanks to the four slotted holes, the housing can be easily mounted on the wall. The openings for the screws are located outside the protective space for the electronics, so no sealing is required. With the cable compression glands, sealing to the probe or data cable is guaranteed even for different diameters. Mounting material for the installation of the transmitter (screws and dowels) are included with the transmitter as free accessories. A large assortment of temperature probes and connecting cables is also available as an option. Important: To prevent measuring errors, the connecting screws for fastening the connecting cable must be firmly tightened.
Open the rotary cover.
You can parameterize your temperature transmitter and set the scaling via the DIP switches. Please use the information from the parameterization table.
Mount your outdoor probe with sufficient distance to vents, windows or doors and preferably on the north wall, alternatively on west or east wall of the building. Avoid direct sunlight and rain. Use Sun Protection if necessary. Please lay the cables downwards so that rainwater can drip off in a defined way. Please consider the permissible ambient conditions during installation.
