The reference design transmits temperature measurements from remote sensors to the central control unit over a 4–20mA current-loop using the highway addressable remote transducer (HART) communication protocol. It consumes less than 3.2mA
This smart transmitter enables low-power temperature measurement from -200 °C to +850 °C with accuracy better than ±0.1% or ±1.0 °C.
Novato’s flexible design supports 2-, 3-, or 4-wire resistance temperature detector (RTD) sensor inputs and works with any type of RTDs, from PT100 to PT1000, making it ideal for a wide variety of industrial applications.
The HART functions set is developed by AB Tech Solution, an engineering firm specialising in product development services for industrial automation applications. The HART stack for Novato runs on the Renesas RL78/G13 microcontroller and supports all universal and common practice commands.
