What is a transmitter?
They are also known as transducers, signal converters or simply converters. They are used to convert physical measured variables such as temperature, humidity, differential pressure etc. into standardized electrical signals.
In the case of a temperature transmitter, the measured variable to be converted is temperature.
The input signal is a resistance value for resistance-based temperature probes and a voltage value for thermocouples. The output signal is usually either 0 ... 10 V or 4 ... 20 mA. Historically, however, there are also 0-1 V / 0-5 V or 0-20 mA signals.
What are outdoor transmitters and what are they used for?
Our outdoor transmitters measure the outdoor temperature or the temperature in cold stores and storage rooms and output this as a standardized signal (4 - 20 mA or 0 - 10 V). In our types, the sensor is placed in a small protective tube. The transmitters for outdoor use are deliberately designed to be inert so that weather-controlled heating and air conditioning systems can continuously and smoothly adapt their output to the outdoor temperature.
What types of outdoor transmitters are there and what are the differences between them?
There are different types of outdoor transmitters. We offer our outdoor transmitters with the external protection sleeve as a simple basic variant, as a standard variant and as a variant with a display with 4-20 mA and 0-10 V output respectively.
The Pt1000 class B sensor is installed in the active temperature probes and you can choose between an output of 4 to 20 mA or 0 to 10 V. The measuring insert is permanently installed.
Configuration of the articles
We offer the following screw connections for our standard variant and the variant with display:
Cable gland, M12 plug connector
How are outdoor temperature transmitters installed and used?
Our outdoor transmitters can be easily attached to the wall using the drill holes. The openings for the screws are outside the protective space for the electronics, so no sealing is required. Mount your outdoor probe with sufficient distance to ventilation openings, windows or doors and preferably on the north wall, alternatively on the 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 manner. Please take the permissible ambient conditions into account during installation.
What are the advantages of outdoor transmitters compared to other types of transmitter systems?
Outdoor temperature transmitters have many advantages, such as accurate measurement, easy installation and integration into existing systems, high durability and reliability
What features and specifications should be considered when selecting an outdoor transmitter?
Factors such as measuring range, output signal, power supply and environmental conditions should be considered when selecting an outdoor transmitter. With our DIP switches, you have a choice of eight measuring ranges. The Pt1000 class B sensor is used for temperature measurement.
We offer a 0-10 V voltage output and a 4-20 mA current output. The ambient temperature of the transmitter is between -30 °C and +70 °C. The voltage supply is 24 V AC ⁄ DC (± 10 %) for the voltage variant and 15 - 36 V DC for the current variant.
