Plug-in transmitter Basic 4-20 mA

The precise Pt1000 plug-in transmitter reliably measures temperatures in ducts and ventilation systems and provides a standardized 4-20 mA output signal. Thus, measured values are transmitted error-free even over long distances. Select the length of the protection sleeve. Measuring range and scaling are easily adjustable via DIP switch. The innovative rotary cover lock enables fast and secure mounting. Due to its robust design, the transmitter is ideal for temperature measurements in gaseous media, e.g. in ducts. Accessories such as immersion sleeves, compression fittings and mounting flanges made of stainless steel, aluminum or plastic are available in our online store.

Plug-in transmitter - Mounting
Open the rotary cover.
You can parameterize the output via the DIP switches. Important: To prevent measuring errors, the connecting screws for fastening the connecting cable must be tightened.
Mounting by using an immersion sleeve
Measurement errors can occur due to heat dissipation to the environment. To keep these as small as possible, we recommend immersing the protection sleeve of your temperature probe as deeply as possible in the medium to be measured during installation. The optimum installation depth should be 10-15 times the Ø of the protection sleeve. Please make sure that you have sufficient space so that you can remove the probe again if necessary.
Mounting by using an immersion sleeve (4): Please make sure that the Ø and the length of the immersion sleeve are chosen according to the installation situation, so that the minimum immersion depth can be reached. 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 in such a way that the protection sleeve touches the bottom of the immersion sleeve and that the air cushion around the protection sleeve is as small as possible. The use of thermal conduction paste can improve the response times.
Mounting in the duct by means of mounting flange
Mounting by means of mounting flange: Please make sure that the Ø of the mounting flange matches the Ø of the protection sleeve. Suitable flanges can be found at testo-sensor.store.
