Automation specialist ifm electronic reports that its TR and TN series temperature sensors are now available with IO-Link.
IO-Link is an intelligent point-to-point connection system for sensors and actuators, which is compatible with existing input/output standards, allowing for parameter setting and diagnosis to be done directly through the programmable logic controller.
The connection system also allows for the cyclical transmission of measured values in digital form. The outputs can also be programmed as conventional switching and analogue outputs.
The TR series enables the connection of separate platinum element sensors with resist- ances of 100 ohms and 1 000 ohms at 0 ºC, in temperature ranges of between –40 ºC to 300 °C.
Evaluation is carried out using analogue, switching, or IO-Link signals. In combination with cable sensors, probe sensors, or special hygienic temperature sensors, a wide range of applications for this technology is possible.
Further, the compact TN-type unit, with an integrated temperature probe, is known for its rapid response times, high pressure resistance and adaptive process connections. Analogue, switching and IO-Link signals are generated and freely programmable between –40 °C and 150 °C.
Both series of temperature sensors have a clearly legible four-digit alphanumeric display, while parameter setting of the units is directly possible on site by means of two buttons. A wide range of accessories, adaptors and connectors ensures easy and safe integration into the application.
Further, the company reports that its TAP series of temperature transmitters is suitable for liquids and gases in hygienic processes, such as those emloyed in the food industry.
The device features the 3.01 Profibus PA profile, including identification and maintenance functions. This allows parameter setting through the process bus, and diagnostics to be conducted remotely.
“Process reliability is the key feature of the TAP series, owing to the internal monitoring inherited from ifm’s TAD sensors. The use of two different sensor elements, which monitor each other in the process, ensures that a developing sensor drift is immediately detected and reliably diagnosed,” says ifm electronic marketing manager Chris Cronjé.
Further, if one element fails, the process continues, with the second measuring element functioning as a backup.
The TAP sensor’s temperature measurement range covers –25 ºC to 150 ºC with a precision of 0,2 K from –10 ºC to 100 ºC, and 0,3 K from –25 ºC to –10 ºC and 100 ºC to 150 ºC. Temperature drift can be monitored down to 0,5 K.
Designed for hygiene applications, the TAP series is European Hygienic Engineering & Design Group-certified, as it features ifm’s Aseptoflex process connection, allowing for its adaptation to hygienic fitting systems.
