SAN JOSE, Calif., Feb. 25, 2014 /PRNewswire/ --Factories can now easily, and
very accurately, measure and transmit industrial temperatures with the Novato
(MAXREFDES16#) reference design, a 4–20mA loop-powered temperature transmitter
with the HART® communication protocol from Maxim Integrated Products, Inc.


Temperature is among the most widely measured parameters in industrial process
control and automation applications. The Novato 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. This smart transmitter enables low-power temperature
measurement from -200-degree C to +850-degree C with accuracy better than
+0.1% or +1.0-degree 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

Key Advantages

  oHigh accuracy: measures temperature from -200-degree C to +850-degree C
    with accuracy better than +0.1% or +1.0-degree C
  oFlexibility: supports a 2-, 3-, or 4-wire RTD sensor input; PT100 to
    PT1000 RTDs
  oLow power: consumes less than 3.2mA
  oHART 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


  o"Factories of the future will need a smart temperature transmitter like
    Novato to measure wide ranges of temperature, get the data to central
    control fast, and consume low power in the process," said Sean Long,
    Director at Maxim Integrated. "By integrating ABTech's HART stack running
    on the Renesas RL78 ultra-low-power microcontroller, Maxim offers a
    complete solution with this design."
  o"Accurate temperature measurement in a factory setting is imperative,"
    said Colin Barnden, Principal Analyst, Semicast. "The proliferation of
    smart sensors in the market will lead us to smarter systems within smart
    industrial applications." 

Size and Pricing

  oPricing starts at $99 (FOB USA).
  oFits into a DIN size B head-mounting enclosure (< 40mm diameter) to meet
    field sensor needs.
