MDR ASSOCIATES LIMITED is an instrument-grade engineering consultancy working from its studio at 6 Queens Court, Queens Court North, Third Avenue, Team Valley Trading Estate, Gateshead - NE11 0BU, United Kingdom (GB). The firm designs control systems that hold their edges to the millisecond, writes the real-time software that keeps a machine and its operator in step, and proves every loop on the bench before a plant ever runs on it. Our work sits where hardware behaviour, timed logic and plant safety meet.
See how we time and prove a systemLogic lane staves — six channels of practice
We shape a control philosophy around the actual physics of the plant, then turn it into loop sheets, cause and effect tables and a signal list that any integrator can build from without guesswork. Careful design up front removes the rework that usually arrives at the worst possible moment.
Our engineers write deterministic software for embedded controllers, PLC targets and edge devices where a late task is a fault. We treat cycle time, jitter and watchdog behaviour as first-class requirements and test them, not merely hope for them.
When a loop protects people, we design it to the relevant safety integrity level, document its proof test interval and keep its separate from the basic process control wherever the standard demands it. Independence and traceability are built in from the start.
We build acquisition chains that stay honest from the transducer to the database, with time-aligned samples, clear engineering units and buffering that survives a network fault. Trend data is only useful when its timing can be trusted.
During the tense weeks before handover we sit beside the commissioning team, watch the first real edges arrive and tune the loops on live data. Faults found on site are traced back to a signal reference, not guessed at.
A system is only as good as the pack that travels with it. We produce readable manuals, as-built drawings, calibration records and maintenance guides so the next engineer can work confidently long after we have left the site.
MDR ASSOCIATES LIMITED opens its winter commissioning calendar, and a short planning call is the fastest way to reserve a bench slot.
Most industrial problems are timing problems wearing a disguise. A valve that reaches its limit switch a fraction late, a scanner that samples just after the part has moved, a safety trip that fires while the process is mid-stroke: these are edges that fell out of step. MDR ASSOCIATES LIMITED was founded on the belief that clear thinking about time, sequence and closure solves more plant problems than any single clever algorithm.
From our base at 6 Queens Court on the Team Valley Trading Estate we work with machine builders, process operators and system integrators across the United Kingdom. Some clients arrive with a fully drawn specification and want a second pair of eyes on the control philosophy. Others arrive with a working machine that misbehaves once a week and a maintenance team that has run out of theories. We handle both, and we treat the diagnosis as seriously as the design.
Our engineers come from backgrounds in automation, embedded electronics and process safety. That mix means a conversation about a jitter budget can move naturally into a conversation about proof test intervals without changing chairs. It is this overlap of control, software and safety that lets us close a loop properly rather than patching one symptom at a time.
A control system is a promise about future behaviour, and a promise is only credible when someone has tried to break it. That is why our control system design work always ends in a test plan. We ask what could make an edge arrive late, what could make a loop open, what a nuisance trip would cost, and we write those questions into the commissioning schedule before they turn into surprises at two in the morning.
The same discipline runs through our safety instrumented systems practice. A safety function that cannot be tested is a safety function nobody can trust, so we define the proof test method at design time and record the result every time it runs. For plants that depend on machine health, our data acquisition platforms provide the evidence trail: time-aligned samples that let a vibration signature be read months later with confidence.
Real-time software is where the theory meets the metal. Our code for embedded and edge targets is written to explicit cycle budgets, instrumented for jitter, and reviewed for watchdog behaviour on the assumption that the fault will occur. When a product must ship on a fixed date, our technical documentation keeps the knowledge inside the building instead of inside the head of one engineer.
We are comfortable in heavy process environments, in compact machine cells and in the awkward space between the two, where a legacy plant meets a modern controller. Typical engagements include a control philosophy study for a new production line, a rewrite of ageing real-time code onto a current platform, a safety system upgrade that must remain live throughout, and a measurement project where poor sample timing has made the existing data useless.
Because the firm is deliberately small, the engineer who scopes your project is generally the engineer who delivers it. That continuity matters when a commissioning date moves, when a supplier substitutes a component, or when an operator raises a question that only the original designer can answer. We would rather decline a job than take one we cannot staff with the right depth of attention.
Every project shares a single ambition: to leave behind a system whose edges are timed, whose loops are closed and whose behaviour has been proven on the bench and on the plant. If that sounds like the level of rigour your next project deserves, our contact page is the right place to begin, and a brief note about your process and timescales is all we need to start.
Whether the problem is a control philosophy that has grown tangled, a real-time task that occasionally overruns, or a safety function that needs its proof test defined properly, a short conversation is usually enough to tell whether we can help. Tell us the machine, the symptom and the deadline, and we will tell you honestly what we would do first.
