A trip amplifier is a device that allows an Analogue signal to be converted to a Digital output. The digital output controls the variation of a physical unit in a system measured by temperature sensors or normalized signals and operates when the measured value goes outside predetermined limits, energising or de-energising the relay controlling devices like valves and actuators.View Category
Amelec has over 45 years of experience supplying signal conditioning instrumentation across the nuclear industry, while supporting our legacy products. Supplying to Sellafield, AWE, Magnox, CCFE, Westinghouse/Springfields Fuelds, British Energy/EDF & and majority of the UK Nuclear power fleet.
As mentioned before we support all of our products even the same products supplied to plants from our founding in 1975. Just as the systems that use our products, we intend to keep our legacy products operational for as long as their systems are operational.
However we also supply new and modernised instrumentation for new projects in the nuclear industry, supplying around 3000 instruments for the Sizewell B new build project, as well as assisting with the general project and maintenance of the applications and also proud to be supporting the Hinkley C project.
AMELEC manufacture & supply signal conditioning/process monitoring & control instrumentation for use within general monitoring, control & safety systems across all areas of a plant. As well as nuclear our products cover Coal fired, Gas Fired, Oil fired, CHP & CCGT, Biomass, Hydro & Wind and more.
In the early days the CEGB approached AMELEC saying they had a need for our type of instrumentation on their power stations. They asked if we would enter into a project with them to demonstrate that our products were suitable for use on their plants. Test programmes were put together by the CEGB and our instruments were type tested at independent test houses. The results from those tests led the CEGB to issue type approval to the largest range of instruments ever covered on the one approval document.
Where we quote /supply instrumentation to those area’s that require full Seismic qualification, the units will have the Surface / Keyhole plate mounting arrangements. These were qualified on a tri-axial seismic table to the Sizewell B spectra 5 x OSE tests (20% SSE), 1x SSE test. In addition they were shaken to 0.25g & 0.4g all sites spectra, passing all tests and giving considerable confidence in the seismic capability. Where we quote / supply our ‘K’ option products, the instruments offered will comply with the radio frequency immunity test in accordance with the CEGB’s DN5, IEC801-3 & IEC61000-4-3 standards. When applied to instruments the standards allow an error of 1% when the equipment is subjected to RF interference in the frequency range 20 to 1000MHz, in a field strength of up to 10V per metre.
Signal isolators provide electrical (galvanic) isolation between the input and output circuits. They couple the signal to the output through a transformer or optical isolator. Signal isolators also break the direct electrical galvanic path between two or more loop points. They protect against dangerous measured-variable voltages and increase protection from surges and spikes.View Category
Signal converters convert the format of the input signals into the desired output format. In addition to the pure conversion of signals, signal converters also offer the possibility of filtering or linearizing signals. A signal transmitter is a device that transmits data from one place to another. In the case of mechanical equipment, a signal transmitter sends a process signal like temperature, pressure or humidity from a measurement apparatus to an electronic device like a panel meter, controller or computer. In the machinery or test environment, signal transmission is of critical importance. This is because of the nature of testing itself.View Category
