4 Unique Product Features that Minimises Operational Stops and Increases Productivity

Temperature - 5941 Number inOperational Reliability

It is our objective to deliver the most reliable temperature transmitters on the market, even when it comes to the most exposed and difficult applications. Why so? Because operational reliability can be directly converted into cost-savings. How much does an hour’s down time in your process cost? And not least, how much annoyance does it cause?Operational reliability is achieved by efficiently protecting the transmitter against outside disturbances. Therefore all temperature transmitters from PR electronics have been developed with a view to achieving a high basic accuracy, maximum protection against electromagnetic noise, and an extremely low temperature coefficient. This reliability is reflected in concrete product advantages satisfying our customers’ demands for quality and stability and always backed up by our five-year guarantee. High immunity to conducted noise: This type of disturbance may come from frequency converters or switchmode power supplies. Our transmitters are tested against 10 Vrms in the range 15 Hz–100 MHz according to requirements from the maritime industry among others.High immunity to HF noise: Airborne disturbances from mobile phones, walkie-talkies etc. All our transmitters are tested at 10 V/m in the entire prescribed range (80-1000 MHz) and thus meet the NAMUR NE 21 A criterion.High immunity to energy-loaded transients: The disturbance comes from e.g. contactors. Our transmitters are surge-tested at a test voltage of 1 kV differential mode and 2 kV common mode according to NAMUR NE 21 A criterion.High immunity to burst noise: Efficient protection against burst noise from e.g. relays. In order to ensure a reliable operation in areas exposed to a high degree of burst noise, we test our transmitters at 2.5 kV for twelve hours. We easily meet the NAMUR NE 21 A criterion prescribing 2.0 kV for 1 minute.Extremely low temperature coefficient: State-of-the-art when it comes to a high basic accuracy and an extremely low temperature coefficient of down to 0.002% - measured according to the European standard IEC 68-2-1 / IEC 68-2-2 / IEC 770 6.2.10.
