With the room transmitter, the temperature measurement signal can be transmitted safely, easily and over long distances to the control system or systems.
You will find the most important information in the following guide
What is a transmitter?
They are also known as transmitters, transducers, signal converters or simply transducers. 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 room transmitters and what are they used for?
Our room transmitters measure the room temperature in indoor spaces such as offices, supermarkets and schools and output this as a standardized signal (4 - 20mA or 0 - 10 V).
What types of room transmitters are there and what are the differences between them?
There are different types of room transmitters. We offer our room transmitters as a standard variant, a stainless steel variant, a design variant and a variant with display, each with a 4-20 mA and 0-10 V output.
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.
How are room temperature transmitters installed and used?
For an accurate measurement of the room temperature, it is important to consider the temperature dynamics in the room. Air circulation should only take place through the openings in the housing cover. Therefore, the transmitter should be installed away from objects or obstacles that block air movement. Please also avoid uncontrolled air currents (draughts) by installing the transmitter near doors or windows (draughts). In addition, the transmitter should not be installed on the colder outside wall.
Wall mounting or on flush-mounted box, Ø 55 mm, base with 4 holes, for mounting on vertically or horizontally installed flush-mounted boxes for cable entry at the rear, with predetermined breaking point for cable entry at the top/bottom for surface-mounted boxes.
What are the advantages of room transmitters compared to other types of transmitter systems?
Room 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 a room 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 version and 15 - 36 V DC for the current version.
