Temperature transducers with option of AS-I communications

Paul Boughton
IFM Electronic is introducing three more temperature transducers, augmenting the company's already extensive selection. These new versions of the TA series provide either a 4-20mA output signal or direct connection to AS-interface.

The clever part is said to come with the TAA131 on AS-i: as long as the master is at least to specification 2.1 the built-in AS-i slave in the temperature sensor is recognised immediately and data transferred with no need for further intervention. Even better, the value is transmitted in ˚C, so no conversion is needed.

All three TA transducers incorporate a Class A Pt1000 sensing element for accuracy and speed of response, reacting as quickly as one second. Measurable temperature ranges start at -50˚C and go up to 150˚C.

The housings are completely sealed and welded, providing not only IP68/IP69K protection, but also excellent mechanical stability. Mounting is simplified with the integrated thread, and electrical connection is via an industry-standard M12 connector.
