Description Of Digital Temperature Switch
TT301 digital temperature switch is an intelligent & digital temperature measurement and control product with temperature measurement, display, output and control functions. TT301 digital temperature switch is made with complete electronic structure, Pt100 temperature probe is located its front end, the output signal is processed by the amplifier, which is with high precision and low-temperature drift, then sent into high precision A/D converter, to be converted to a digital signal for microprocessor, the signal after processed will control two relay output, and realize the temperature measurement for the system. The use of the TT301 digital temperature switch is very flexible. TT301 digital temperature switch is also effortless to operate and adjust.
Application Of Digital Temperature Switch
TT301 digital temperature switch is widely used for liquid temperature measurement, display and control in electricity, water, petroleum, chemical, mechanical, hydraulic and other industries.
