At the July technical evening, acting chairman of the SAIMC Tshwane branch, Petrus Klopper, said that with three major universities in the area – UP, TUT and UNISA – the branch is working on initiatives to involve more students in SAIMC activities to expose them to industrial automation and control and meet with industry leaders. He said that it is important for the SAIMC to engage more regularly with the control engineers of tomorrow and urged members to offer their time and share their expertise.

The July meeting was held at the state-of-the-art training centre at Ifm Electronics, Route 21 Business Park in Centurion, where all future branch meetings will be held. The branch is also planning a fundraising golf day on 27 August at the Swartkop Country Club. A few four balls are still available.

The speaker at the July technical evening was Benjamin Mlangeni of Endress+Hauser. He presented various temperature measurements options and demonstrated the latest technology on contact temperature measurement.

Endress+Hauser recently introduced TrustSens, said to be the world’s first self-calibrating resistance temperature detectors (RTD) sensor in two product ranges, QuickSens (quicker response RTD sensor for process optimisation) and StrongSens (strong RTD sensor for robust application). The sensor elements use thin-film technology based on silicon, embedded in ceramic potting. “We have developed an automated manufacturing process with computer-controlled robot technology creating a valuable competitive edge and providing a high level of safety due to a consistently high quality”, Mlangeni said.

The advantage of the TrustSens range is that it performs an automated inline self-calibration at 118°C during each SIP which provides for early detection of drift, straightforward visual monitoring via LED, and short calibration intervals reducing the risk of incorrect temperature measurements. Accuracy of 0,03°C can be achieved which is ten times better than that of a standard Pt100 class AA sensor.

He also talked about instruments with Heartbeat technology, which deliver standardised diagnostic messages for economical maintenance. Verification occurs directly in the measuring point, without process interruption, in order to reduce verification efforts. It includes monitoring data which facilitates predictive maintenance for further optimisations of the process. Heartbeat Technology provides easier and better control of measuring points.
