I am using an AD5700 as HART modem on my board. For demo purpose, I am looking for low cost light HART sensors .
Have you some manufacturers to propose ?
We can only provide support on the AD5700 modem itself.
For support on other specific HART registered components, please visit the HART foundation website.
That said, what you could consider is a smart sensor like the CN0267 which incorporates a bridge transducer/RTD sensors, micro controller and loop powered DAC/HART modem.
For your application, you would need to incorporate the light sensor which would not need to HART enabled.
Circuit Note | CN0267 | Complete 4 mA to 20 mA Loop Powered Field Instrument with HART Interface | Analog Devices
Hopefully this helps.
