1000 Ohm Platinum RTD
Rangeable Temperature
Transmitter
Zero setting can be anywhere from -50° to 212°F (-45° to
100°C) and span from 30° to 320°F (17° to 180°C). The Model
TT809 comes factory calibrated, and once installed, it can
be field calibrated with high precision DVM and decade box.
The Model TT809 is easily calibrated by adjusting the zero
pot to match the calibration reference.
The gasketed cast-metal housing provides excellent weather
resistance. The screw terminal connections on the
transmitter circuit, 1/2" NPT threaded connection, and
adjustable mounting brackets simplify installation. Several
varieties of precision 1000 Ω platinum RTD probes are easily
mated with the transmitter housing.
Switch-set rangeable with zero and span
• One-point field calibration
• Nonpolar loop connections
• Weatherproof sensor interface housing
• Non-interacting zero/span adjustment
