At the SPS IPC Drives fair in Nuremberg, Turck is presenting its BCT capacitive sensors with an IO-Link interface. IO-Link makes it easy to set the parameters of the capacitive switch in applications such as level control.
The internal process value of the sensor can be displayed in different damping states via FDT frameworks such as Pactware or the machine controller. This simplifies the teaching of the sensor in difficult applications and enables the diagnosis of the sensor or detects container contamination. Alternatively, the BCT sensors can be set using teach buttons or teach cable, depending on the particular model. This last feature provides protection against unauthorised manipulation during operation.
The BCT Capacitive Sensors with IO-Link enables the user to carry out predictive maintenance. The sensor reports by IO-Link event if the temperature in the housing exceeds the critical value. The state of the power supply is also monitored and reported. Using this feature the user can detect a possible wire break early on and can rectify the weak point before a fault brings the plant to a standstill.
The BCT Capacitive Sensor meets the requirements of protection type IP67 and is available as an M18 variant with a 5 mm standard switching distance and as an M30 variant with a 10 mm switching distance – measured for flush mounting. If the sensors are mounted as non-flush devices the switching distance is increased by a further 50 %. Both variants are available with or without teach buttons.
