Temperature Controller Calibration
Temperature controller calibration is the process of verifying and adjusting the accuracy of temperature control instruments by comparing their readings and output responses against NIST-traceable reference standards. Temperature controllers regulate heating and cooling processes by receiving input from temperature sensors—such as thermocouples, RTDs, and thermistors—and modulating output signals to maintain a desired setpoint.
- PID Temperature Controller Calibration
- Profile Controller Calibration
- Single-Loop Temperature Controller Calibration
Temperature Transmitter Calibration
Temperature transmitter calibration is the process of verifying and adjusting the accuracy of a temperature transmitter's input-to-output conversion against traceable reference standards. A temperature transmitter receives a signal from a temperature sensor—such as an RTD, thermocouple, or thermistor—and converts it into a standardized output signal, typically 4–20 mA, for transmission to control systems.

Calibration Demand in Green Bay
Temperature Calibration Demand in Green Bay, WI
Green Bay is a major hub for food processing and packaging manufacturing in northeastern Wisconsin, creating strong demand for precise temperature calibration services. Schreiber Foods, headquartered in Green Bay with over 10,000 employees, operates large-scale dairy manufacturing lines where pasteurization and cold storage temperatures are monitored continuously. American Foods Group, a family-owned beef processor established in 1946, relies on calibrated temperature instrumentation throughout its slaughter and processing operations to ensure product safety. BelGioioso Cheese, also based in Green Bay, produces Italian specialty cheeses requiring strict adherence to aging and storage temperature specifications.
Beyond food processing, Green Bay Packaging operates one of the most modern recycled paper mills in the world at its Green Bay Mill Division. Industrial drying, coating, and curing processes at the facility demand accurately calibrated temperature sensors to maintain product consistency and energy efficiency. Schwabe North America, a pharmaceutical manufacturer located in Green Bay, is subject to stringent temperature validation requirements across production and storage environments.
Local Compliance Requirements
Food processing facilities in Green Bay are regulated under the FDA Food Safety Modernization Act (FSMA) and 21 CFR Part 117, which mandate documented preventive controls including temperature monitoring at critical control points. Wisconsin has adopted the 2013 FDA Food Code through the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), requiring licensed food establishments to maintain calibrated thermometers and verifiable temperature records. The Brown County Environmental Health Unit enforces these standards through routine facility inspections.
- USDA FSIS regulations require continuous temperature monitoring in meat and poultry processing facilities such as those operated by American Foods Group
- ISO/IEC 17025 accredited calibration ensures measurement traceability to NIST standards, satisfying audit requirements under FDA 21 CFR Part 117 and FSMA
- OSHA process safety management standards apply to industrial operations where temperature excursions pose worker safety risks
- Pharmaceutical manufacturing at facilities like Schwabe North America requires temperature instrument calibration compliant with FDA 21 CFR Parts 210 and 211
In-Depth Reference for Green Bay
Industrial Demand Drivers in Brown County and the Fox River Corridor
Paper and packaging manufacturing concentrated along the Fox River corridor establishes one of the primary demand sectors for temperature instrument calibration in the Green Bay area. Georgia-Pacific operates converting and tissue-grade production in the metro, and Green Bay Packaging - headquartered on the city's south side - runs integrated paper mill operations where process temperatures across pulp drying, coating, and curing zones must remain within defined control bands. Temperature transmitters embedded in these continuous-process lines drift gradually over service hours; recalibration intervals in that environment are set not by convenience but by the uncertainty contribution each instrument makes to process capability calculations and internal quality system requirements. The Port of Green Bay, one of the larger freshwater commercial ports on the Great Lakes, adds supplemental demand through temperature-sensitive bulk cargo handling and cold-storage warehousing along the waterfront industrial zone.
Dairy and food processing form a distinct second sector, concentrated across Brown, Manitowoc, and Calumet counties. Schreiber Foods, headquartered in Green Bay, operates cheese and dairy processing at significant scale, and Associated Milk Producers and Foremost Farms maintain substantial regional production presence throughout the Fox Valley. Cold-side operations - pasteurization lines, aging rooms, refrigerated warehousing - rely on calibrated data loggers and chart recorders to generate the continuous temperature records required under Wisconsin DATCP enforcement of the Pasteurized Milk Ordinance and under FDA 21 CFR Part 117 Hazard Analysis and Risk-Based Preventive Controls. Out-of-tolerance recording instrumentation can invalidate hours of cold-chain documentation, triggering product holds and regulatory notification - an outcome that positions calibration interval management as a compliance function rather than a routine maintenance line item.
Traceability Standards and Acceptance Criteria for Accredited Temperature Calibration
Calibration of temperature instruments in this service category proceeds against a traceability chain anchored to ITS-90, the International Temperature Scale of 1990. Laboratory reference standards - Standard Platinum Resistance Thermometers (SPRTs) or well-characterized PRTs - serve as the comparison baseline during calibration of industrial RTDs, thermocouples (TCs), and recording instruments. The unbroken chain from NIST through laboratory reference standards to the unit under calibration is documented on each issued certificate and is the mechanism by which that certificate acquires standing under ISO/IEC 17025-aligned quality audits. Measurement uncertainty, expressed at a stated coverage factor, must be demonstrably smaller than the acceptance tolerance of the instrument being calibrated; facilities that accept certificates without a reported uncertainty value are accepting an unknown risk in their measurement system.
Thermocouple calibration follows ASTM E220, Standard Test Method for Calibration of Thermocouples By Comparison Techniques, which defines comparison bath and furnace methodology, required reference probe uncertainty, and point selection logic for characterizing instrument behavior across the in-service range. Type K and Type J thermocouples are prevalent in the paper mill and food processing environments characteristic of Brown County manufacturing. Calibration spans bracket actual operating temperatures rather than simply covering a nominal instrument range, and tolerance evaluation references ASTM standard limits for the thermocouple type - or tighter, facility-specified acceptance criteria where process control or regulatory requirements demand closer conformance.
ISO/IEC 17025 accreditation, administered through A2LA (the American Association for Laboratory Accreditation), establishes the technical competence and measurement uncertainty framework under which calibration certificates carry recognized validity for regulatory audit purposes. Facilities operating under FDA oversight, SQF or BRC third-party certification, or ISO 9001-based quality management programs increasingly require that records originate from a laboratory with a confirmed, published accredited scope - an A2LA scope number on the issued certificate is the documentary evidence auditors expect to find. In dairy and food processing applications specifically, chart recorder and data logger calibration must address the complete measurement chain, from probe tip through signal conditioning to the final electronic or printed record. PMO-aligned programs treat this chain as a single traceable unit; acceptance tolerances for pasteurization monitoring are commonly held to +/-0.5 degrees C or tighter, placing more stringent demands on reference equipment stability and uncertainty budgets than those typical of general manufacturing environments.
