TT421
Head Mount Smart Temperature Transmitter 4 to 20 mA + HART.

The Digital Temperature Transmitter TT421 is the cost effective solution for temperature measurement and control dedicated for head mounting.

The Smar TT421 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.
