Thermocouple & RTD calibration · Mining

Thermocouple calibration for mining

Processing plants and site laboratories in the WA mining sector use thermocouples and RTDs in furnaces, dryers and sample preparation, and the readings feed process records and assay procedures that are audited.

Thermocouples and RTDs are the sensors behind process control, ovens and test rigs, and their errors are invisible until something is checked against a reference. AmpTech calibrates thermocouple and RTD sensors in our Caversham lab against a reference thermometer traceable to national standards, either as a sensor alone or as a sensor-and-indicator system.

Interval in mining

12 months

Process and laboratory procedures

Setting the interval

Twelve months is standard. Thermocouples that run hot age quickly and are often treated as consumables on a shorter interval; RTDs are more stable but suffer from lead and connection problems.

What the calibration covers

Sensor output against a reference thermometer at points between −25 °C and +140 °C
System calibration — sensor plus indicator read together, where you send both
Indicator accuracy alone, using simulated inputs, where the sensor is fixed in plant
Lead and connector condition, which affects thermocouple readings

What your certificate records

The certificate format mining procurement and audit teams ask for: the equipment under test, its serial number, the reference instruments used, as-found and as-left readings, environmental conditions and a traceability statement, plus the thermocouple & rtd-specific items below.

As-found and as-left readings at each temperature point
Whether calibrated as a sensor alone or as a sensor-and-indicator system
Reference thermometer and equipment used, with traceability
Environmental conditions at the time of calibration

Standards & frameworks in mining

ISO 9001 quality management system
AS/NZS 3760 for portable electrical equipment on site
WHS (Mines) Regulations 2022 (Western Australia)
Operator-specific prequalification requirements

How mining clients get thermocouples and RTDs to us

Calibration is performed in our Caversham lab — not on site. We collect from and deliver back to mining workshops and offices across Perth, and instruments from regional sites come by freight or via your Perth base.

Mining head offices in Perth CBD and West Perth
Welshpool / Kewdale freight and equipment hubs supporting Pilbara operations
Malaga and Bayswater workshops fitting out mine vehicles and tooling
FIFO bases at Perth Airport — fast-turn calibration before flights out

Working with mining procurement

We work with mining procurement teams on POs, prequalification packs and instrument-by-instrument quotes. Every calibration ships with a clear certificate showing as-found / as-left readings and a traceability statement — exactly what auditors and PMC reviews ask to see.

FAQ

Thermocouple & RTD calibration for mining FAQs

Can you calibrate the spare sensors we keep on the shelf?

Yes. Spares can be calibrated in the same batch so a replacement goes into service with a current certificate rather than waiting for the next round.

Should I send the indicator with the thermocouple?

If you use them together, yes — calibrating them as a system checks the whole measurement chain. If the sensor is fixed in plant, we can calibrate the indicator alone using simulated inputs.

What temperature range can you cover?

Our dry-well runs from −25 °C to +140 °C, so sensors used within that band are calibrated against the reference thermometer at points you nominate. Thermocouples that run hotter in service can still have their indicator checked by simulation, which has no such limit — we will explain which parts of the chain the certificate covers.
