The Water-Tight CIP RTD Assembly houses an optional integral Series 450 Temperature Transmitter (no connection head is required) that is ideal for monitoring temperature in small areas such as tanks and pipes. The water-tight construction meets the NEMA 6P requirements. Assemblies are supplied with a surface finish that meets or exceeds 32µin Ra. Surface finishes of 15µin Ra or better are available upon request. Standard units include a M12 process connection housing. The transmitter is a 2-wire unit with an analog output and 2 second response time. It has measurement input for Pt100 resistance thermometers (RTD) in 4 wire connections. Transmitters can be ranged from (-51 to 160) ºC -60 to 320 ºF with a 10 ºC 18 ºF minimum span requirement. Ambient temperature limits for the M12 connector is (-40 to 85) °C.
