The ABB PFTL101AE 0.5KN sensor was developed in Vstross, Sweden in the early 1950s and patented in 1954. ABB’s Pressductor ® technology is based on the so-called magnetoelastic effect (magnetoelasticity), in which the magnetic mechanical forces of certain steels change.
When the ABB PFTL101AE 0.5KN sensor is subjected to a mechanical force, changes in the magnetic field produce a measurement signal. (Move your mouse over the image to see these changes.) Since this signal is not associated with any physical movement or deformation, the sensor combines sensitivity with excellent overload tolerance, with almost no built-in load number limit.
The ABB PFTL101AE 0.5KN analog input/output interface is generally used to sense the signal generated by the sensor. These interfaces can be used to measure flow, temperature and pressure, and can be used to control voltage or current output devices. Typical ranges for these interfaces are -10 to +10V, 0 to +10V, 4 to 20mA, or 10 to 50mA. Some manufacturers have special analog interfaces designed on the PLC, so that low level signals can be received, such as RTD, thermocouples, etc. In general, this type of interface module can be used to receive different types of thermocouple or RTD mixed signals on the same module.
