Description
The special constructions of temperature sensors for rail technology include sensors with flange housing, oil sump sensors and versions with brass or stainless steel screw-in housing. The key difference from the standard versions is the housing geometry. The technical specifications are almost identical. One or two Pt100/Pt1000 chip sensors in 2, 3 or 4 wire circuits are used as measuring resistors. The cable connection consists of a silicone-free, halogen-free, screened hose line and can be additionally protected against external influences with plastic corrugated tube or rubber fabric hoses. Cable screw connections and plug connections are available in numerous versions and are adapted to the project in line with the application and customer specifications.
Assembly variants
Special construction: contact sensor
The sensor has a Pt1000 measuring resistor in a 2 wire circuit. Integrated into an aluminium sleeve, the sensor in screened design serves to monitor the power electronics. The shield is fixed on the sensor housing; the fastening hole has a diameter of Ø 3.2 mm. Other sleeve and drilled hole dimensions are available on request.
Special construction: oil sump sensor
In this construction, the measuring resistor is installed in a brass screw-in housing. This construction is often used as an oil sump sensor for gear monitoring in locomotives. The technical values and internal structure are identical to the temperature sensors in the standard housing. The changed housing geometry makes it easier to assemble at the measuring position.
Special construction with protective pipe design
This construction is perfect for monitoring the oil temperature in compressors, for example. The width across flat, the thread and the protective pipe length can be adapted as needed. Platinum measuring resistors are installed as standard. However, bimetallic switches can also be used.
