Deadband cFP-RTD-122

[uxpro]

Is there any useful application for the Deadband feature in the module cFP-RTD-122? In my application the measurements range is from  40 to 120 ªFSo  I'd like to apply some deadband to the sensor readings but it seems that the module has a range between -3xx to 15xx ªF wich is why a 1% Deadband would be  180 ªF what isn't useful, Does anyone know the effective deadband resolution? If I set it to 0.0001 % will it work? Im looking for 0.05 ªF Deadband value. I've already read the help in MAX so I don't really know if taking the Farenheit range as the reference for the 100% deadband is correct can anyone help me to clarify this one?.

Hi uxpro.

The Deadband's resolution depends on your instrument's resolution. In the cFP-RTD-122 you have 16 bits of resolution so you have 65536 possible levels (100%), the Deadband resolution will be 0.0015259%. The Farenheit range is indeed the reference for the 100% deadband.

I hope this helps clarifying the situation.

Regards.

Say that the cFP RTD-122 ªF Range goes from -300 to 1500 than I have a 1800 ªF Range, if I pick the smallest percent value it would be 0.0015 % that makes 0,027 ªF ?

Hi uxpro.

Yes, that should be correct.
