INDUSTRIAL RESISTANCE TEMPERATURE DETECTORS (RTDs)
Tel-Tru resistance temperature detectors (RTDs) are designed for the most demanding process automation applications. A wide range of configurations are available to meet the requirements of many markets including Chemical Processing, Oil and Gas, Construction, Cold Storage, Water / Wastewater, HVAC, and OEMs.
NPAA3, which can be paired with a connection head and programmable transmitter for 4-20 mA, HART or mV output, using 2 or 3 wire PT100 sensors. Unterminated (bare wire) or M12 connection termination options are also available.
NTAA3 features a PT100 RTD with a factory configured, built-in 4-20mA transmitter and termination options that include an M12 connector with or without mate and cable, or strain relief with cable.Tel-Tru process automation RTDs are highly configurable to fit your temperature requirements and deliver outstanding reliability. Standard assemblies include a proven thin film PT100 platinum RTD sensing element, packaged in a welded 316L stainless steel probe. Assemblies include threaded process connections and may be used with a thermowell, which can be purchased separately.
