When pharma equipment goes down, the problem rarely lives in just one place. We troubleshoot across the instrument, the control loop, and the equipment itself — so you call one number instead of three.
Most field-service vendors are experts in one layer. CCS works across all three under one visit — which matters because the symptom you see almost never lives where you expect it to.
The probe itself. RTDs, thermocouples, pressure transmitters, flow meters, level sensors, gauges. Is it failing, drifting, dirty, mounted wrong, or simply at end of life? NIST-traceable verification answers the question definitively.
The signal chain between the probe and the controller. 4–20 mA loop integrity, terminations, signal noise, grounding, transmitter aging, I/O card faults. Half the "probe drift" we get called for ends up here.
The PLC, the HMI, the panel hardware, the interlocks, the alarms that won’t clear. Where the symptom shows up most visibly — and where the actual root cause lives least often.
From a single failed RTD to a control loop that hasn’t been right since the last upgrade — if it’s pharma process equipment and it’s not working, we work the problem.
RTDs, thermocouples, pressure transmitters, flow sensors, level switches, magnehelic gauges, and process analyzers. We chase the failure mode, not just the symptom — so the replacement we install isn’t the third one this year.
Loop integrity, signal noise, intermittent readings, transmitter drift, I/O card faults, grounding problems. End-to-end signal-chain verification from the probe to the PLC tag — and clear documentation of where the fault actually was.
When a probe shows up out of tolerance, the question is “why?” and “what does this mean for production?” We do the investigation, capture the as-found data, and produce the GMP documentation your QA team needs for impact assessment.
Stuck alarms, interlocks that won’t clear, phantom faults, sequence issues, recipe-related errors. Allen Bradley and Automation Direct platforms. (PLC code authoring is engineering work — see our Engineering Services page.)
Panel-level diagnostics. SSRs, contactors, relays, fuses, power supply faults, grounding problems, signal-power separation issues. Reading prints, finding the fault, making the fix — with the right documentation for your QMS.
When a routine cal reveals a failed instrument, we don’t just write up the OOT and leave. Where possible, we replace, rewire, requalify, and restore service in the same visit — saving you a second mobilization and the downtime in between.
Clients with an active CCS calibration program management engagement get priority response. Call before noon and we’ll have a technician routing to you the same business day, schedule permitting.
First-time and as-needed clients get a response within one to two business days. We’ll triage by phone first to scope the visit — sometimes the answer doesn’t even need one.
Being explicit about scope saves everyone’s time. The work below maps to what we’re actually good at. Anything else, we’ll either refer you or coordinate with the right vendor — we won’t take the work just to take it.
For anything in this column, we’re happy to coordinate with your OEM, recommend a specialist, or work alongside them on the parts we can. Tell us what’s broken — we’ll tell you who should fix it.
Every job follows the same five-stage flow. The fastest fixes never leave stage 2.
Call or email. Be specific: what is it doing, what is it not doing, what changed recently. Photos of the panel, the HMI alarm, or the instrument tag are worth their weight — send what you have.
Phone or remote diagnostics where possible. Sometimes the answer is reachable without a site visit — a setting that needs to change, an alarm that needs to be acknowledged, a procedure that needs to be followed. When it isn’t, this is where we scope the visit accurately.
Reference standards and common spares in the truck. We arrive prepared for the failure mode triage suggested, plus enough overlap to handle the failure modes triage didn’t.
We don’t stop at the symptom. If we find a failed probe, we ask why it failed before we replace it. If the answer is “this is the third one in two years,” the right fix probably isn’t another probe.
Service restored, NIST-traceable verification where appropriate, and a clean GMP-formatted service report — same day where the scope allows. Everything your QA team needs to close the event in your QMS.
