This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
Transiting legacy coldchain to digital
In the retail market the majority of installations utilize legacy
temperature monitoring solutions using PT-100 sensors connected to a
control board. I have written previous about it here.
The fundamental problem with controller boards is that temperature
readings are localized and any readings need to be manually transcribed
for record keeping purposes. This process is prone to human failure as
there is insufficient automation.
