 TT411
Panel Mount Smart Temperature Transmitter
4 to 20 mA + HART
The Digital Temperature Transmitter TT411 is the cost
effective solution for temperature measurement and control dedicated
for panel mounting.
The Smar TT411 is a powerful and extremely versatile
programmable temperature transmitter, which can be used with practically
all relevant temperature sensors as well as with load cells, resistance
position indicators, etc.
A same unit can be used for different measuring ranges
and many types of sensors reducing drastically calibration and maintenance
time.
Complete configuration is possible using PC software
interface (CONF401) or via Hand-Held (HPC301). Configured to customer specs, prior to shipping.
