Pyromation A3 20N 486685 Temperature Sensor Assembly

The Pyromation A3 20N 486685 Temperature Sensor Assembly is an industrial temperature sensing package designed for continuous process temperature measurement in harsh environments. It is used in furnaces, heat-treating systems, power generation equipment, chemical processing plants, and general manufacturing machinery that require reliable temperature feedback, with maintenance teams, OEMs, and system integrators using it for repair, retrofit, expansion, or replacement of existing thermocouple or RTD assemblies. Identified by part number 486685 and model A3 PYROMATION 20N, it presents a RTD or thermocouple sensor assembly (exact type not specified) with RTD resistance or millivolt output, typically featuring a 316 stainless steel sheath and a general purpose connection head; mounting can be threaded or thermowell mounted depending on the installation. An optional 4–20 mA head-mounted transmitter is available, and the unit is designed for outdoor/indoor industrial service in chemical, petrochemical, food processing, and power industries, delivering durable, continuous temperature monitoring for long service life.
