"As the Lead C&I Engineer at Cockenzie Power Station I have used PR electronics modules for several years and they are a cost effective replacement for many of our existing systems and I also use them on new installations. They have been very reliable and are easily configured.”
– Fraser Gordon, Cockenzie Power Station, Scotland.
“We decided to choose the products of PR electronics because of the user-friendliness, together with the distinct data sheets. Swift delivery and good technical support also played a part in the decision-making process.”
– Hans Venema, Teamleader Maintanance, Eemscentrale, Electrabel Nederland n.V., the Netherlands.
“We use PR electronics’ modules because they are universal, reliable and easy to program, and because of the competent technical advising and short delivery time.”
– Jean-Luc Vandevelde, Instrumentation Technician at the EDF Power Station in Porcheville, France.

Power generation plants — whether coal, gas, nuclear, or renewable — rely on hundreds to thousands of analog measurement points for temperature, pressure, flow, level, and vibration monitoring. Signal conditioning devices from PR Electronics provide galvanic isolation to eliminate ground loops between distributed field instruments and centralized DCS systems, convert between signal standards (RTD to 4-20 mA, frequency to analog), and provide signal splitting for redundant monitoring. The PR 4116 Universal Transmitter and PR 9116A Universal Converter are widely used across the energy sector for their versatility and reliability.
Key products for energy sector applications include the PR 4116 Universal Transmitter for multi-input signal conversion with relay alarm outputs, the PR 4179 AC/DC Transmitter for electrical current and voltage monitoring of generators and motors, the PR 3108 Isolated Splitter for feeding one sensor signal to both the process control system and an independent safety system, and the PR 9106B HART Transparent Repeater for safety-critical measurement loops. These devices support the high availability requirements of power plants where unplanned downtime costs millions per day.
IEC 61508 defines the functional safety requirements for electrical, electronic, and programmable electronic safety-related systems. In power plants, safety instrumented functions (SIFs) for boiler protection, turbine overspeed trips, and combustion safeguards require SIL-rated components throughout the safety loop. PR Electronics 9000-series devices carry SIL 2/3 full assessment certification per IEC 61508:2010, enabling their use in these critical protection systems without requiring additional architectural constraints for systematic capability.
Danish CHP station achieved stable temperature signal surveillance in the boiler room – also at 60˚C.
The members of the maintenance team at Fyn Power Station were fed up getting error messages and false system alarms from one of the boiler’s temperature surveillance systems. The problem occurred when the ambient temperature approached 60˚C. The solution to the problem did not seem straight-forward, but after a talk with one of PR’s sales engineers they decided to do a test set-up with PR 3111 isolated TC converters – and that solved the problem … also at 60˚C .
