Test and Measurement Forum

I need a Data Logger to put down a process line that includes a Hot Air Dryer and a Vacuum Dryer, to monitor the temperatures through the cycle. The whole Cycle will take about 25 minutes. Temperatures will range between 10 and 100 degrees Celsius, while the pressure will drop to around 5 millibars in the Vacuum stage. The parts that I want to measure the temperature of are placed in a basket and are picked up and moved automatically down the process line, so cable attachment to the logger is not a practical possibility, especially as the vacuum enclosure has to be tightly sealed
I have used, and still have somewhere an old serial ported TC-08, but that won't do here because of the need to have it connected to the PC and power supply.
I suppose 1 second intervals will be OK, with a resolution of 0.1 degrees. I need something that will store this data to a memory chip, that I can later download from. Also, as the whole Logger will be subject to the low pressure, it will obviously need to be safe at this low pressure.
It doesn't appear from the website that you have such a device, but I'm asking anyway, or can you suggest another solution to my problem or another supplier that I might ask?

Hi there,

Thankyou for your inquiry with regard to your temperature monitoring requirement.

Unfortunately due to the unique requirements of your temperature logging requirements we do not have any products that benifit you.

Just as a point of interest please see one of systems that can be used however it is connected via cable:-

EnviroMon is a very flexible data logging system. It is made up of a number of separate modules: you simply choose the modules that you need to do the job.

There are four main sections to the system:

Logger
Converters
Sensors
Alarms

I certainly think that you should consider a professional data logger that can withstand the environment.

See for example here:

They are certainly not cheap, but they can perform the job
