Temperature recorders log temperature over time for audit and compliance, while temperature transmitters output a real-time analog or digital signal to a control system. Pick a recorder when you need traceable history; pick a transmitter when you need live control.
Industrial temperature recorders in 2026 split into four duty classes: single-use USB loggers, multi-channel paperless recorders, chart paper recorders, and IIoT wireless nodes. Pick by sensor count, accuracy class, and hazardous-area rating; the sweet spot for process plants is a 16-channel paperle
Temperature recorders are specified by five engineering gates: sensor range, accuracy, logging interval, memory depth, and output/interface. For cold-chain and lab work, a -40 to +100 °C range, ±0.1 °C accuracy, and 2 s to 24 h intervals cover most use cases.
Bimetal thermometers give a local mechanical read with no power, while temperature sensors (RTD, thermocouple) output an electrical signal for control loops. Choose bimetal for ≤600°C visual indication on pipelines; choose RTD/TC sensors where you need 4-20 mA, HART, or PLC input.
Industrial bimetal thermometers cover -50 to 500 °C in standard stainless-steel dial form, with 1.5% accuracy class and 1/2 NPT process connection as the dominant factory default in 2026 sourcing catalogs.
