Hi All, A pilot plant is being constructed in Mongolia, which has heap leach (insulated). The intent is to monitor the heap temperature (~ 16 points) and record the temperature (manual operation). The Client does not wish to install 16 Temperature gauges (but rather 16 temperature sensors and one hand held monitor).
I am thinking of installing 16 RTDs and wiring them back to a control room using RTD extension cables. Using a hand held RTD monitor the operator can measure and record all 16 temperatures. Although this sounds quite simple, I have the following concerns:
- The outside temperature can fall to -30 deg C during winter. Are RTD extension cables capable of withstanding these lower temperatures?
- Will the hand held monitor work properly during winter (compensating for the ambient outside temperature, whilst the measured temperature will be between 30 & 55 deg C)?
- Is there a better way of monitoring these temperatures? As usual, being a pilot plant, the Client is frugal with the dollars and cents.
All pointers and suggestions are appreciated.
