high accuracy temperature sensors

Postby mspencer06 » Thu Apr 06, 2006 5:52 pm


I have an application where I require highly accuarate measurements of water temperature (see attached schematic). I work for a hydroelectric facility that is seasonally affected by cold water temperatures and frazil ice. In order to reduce the effects of frazil ice, we have to closely and accurately measure the water temperature at our forebay headworks as the water temp approaches 0.00 deg C. Our current system is now obsolete and requires replacement. We require 4 high accuracy sensors as illustrated with an accuracy near +- 0.001 deg C that would be able to provide a 4-20mA output. The operating range in which we're most interested is between -1 - +3 deg C.

Your assistance is appreciated.

Hi Mike

Thank you for your post.

Unfortunately none of the sensors that we currently supply have this accuracy. Instead I would recommend contacting Kalestead as they have a wide range of sensors and may be able to help you.

Best Regards
