Our screw-in transmitters are ideal for measuring temperature in pipes and containers.
The following guide provides you with the most important information
What is a transmitter?
They are also referred to as transmitters, transducers, signal converters or simply converters. They are used to convert physical quantities such as temperature, humidity, differential pressure, etc. into standardised 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 10v or 4 20 ma. However, for historical reasons, 0–1 V / 0–5 V or 0–20 mA signals are also still used.
What are screw-in transmitters and what are they used for?
Our screw-in transmitters are ideal for measuring temperature in pipes and containers. With their screw-in thread and M12 connector, they can be quickly installed and connected in the process. You can find immersion sleeves and compression fittings that perfectly match our screw-in transmitters in the accessories.
What types of screw-in transmitter are there and what are the differences between them?
We offer you four different screw-in transmitters in our shop. We distinguish between the screw-in thread G1/2 ‘ and G1/4 “ and the output 4-20 mA and 0-10 V.
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.

With our screw-in transmitters, you can choose the mounting length.
We offer the following mounting lengths (mm): 50, 100, 150, 200
How are screw-in transmitters installed and used?
Heat dissipation to the environment can cause measurement errors. To keep these as small as possible, we recommend that the protection sleeve of your temperature probe be immersed as deeply as possible in the medium to be measured when installed. The optimum installation depth should be 10-15 times the diameter of the protection sleeve. Please make sure that you have enough space to be able to remove the probe if necessary.
Installation by using an immersion sleeve: Please make sure that the diameter and the length of the immersion sleeve are selected to match the installation situation so that the minimum immersion depth can be achieved. Since the probe is not inserted directly into the medium, but via the immersion sleeve, the response times are somewhat slower. The probe should be selected so that the protection sleeve touches the bottom of the immersion sleeve and the air cushion around the protection tube is as small as possible. The use of thermal conduction paste can improve the response times.
Which properties and specifications should be considered when selecting a screw-in transmitter?
Factors such as measuring range, output signal and power supply should be considered when selecting a screw-in transmitter. The Pt1000 Class B sensor is used for temperature measurement.
We offer a voltage output of 0-10 V and a current output of 4-20 mA. The power supply is 12 to 36 VDC.
