Temperature measurement over the -200°C to 850°C range with better than ±0.1% accuracy is offered by Maxim's Novato temperature-transmitter reference design. The Novato reference design offers a 4-20 mA loop-powered temperature-transmitter with the HART® communication protocol. 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.
Features and Benefits
- High accuracy: measures temperature from -200°C to 850°C with accuracy better than ±0.1% or ±1.0°C
- Flexibility: supports a 2-, 3-, or 4-wire RTD sensor input; PT100 to PT1000 RTDs
- Low power: consumes less than 3.2 mA
- HART Communication Protocol: the HART functions set is developed by AB Tech Solution, Westford, MA, an engineering firm specialized 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.
