I need to get some dataloggers set up. We will be logging voltage only. For discussion purposes let's just say I need to get one system set up. Here are the requirements:
Store minimum 30 days of data.
Log voltage only.
When I look at Fluke all I come across are the Fluke 287 & 289 and they only hold 10,000 and 15,000 records respectively.
There is the Extech/ FLIR DL160 which has 256,000 records. At one per second that only gives me 256k/84,600= 3 days. If I bump it to one per 12 seconds (5 per minute) I can stretch that to 35 days, but what good is 5 second interval data?
On a Fluke page of a discontinued product (Fluke 189) it said up to 400 hours with extended battery pack. That 400 hours is 16 days. I don't care about battery life; I can build whatever power supply I need. It's the data records I need.
I know there are people on here who have continuous datalogging. How do you do it?
My only restriction is I don't want to have to have a pc out in the field environment due to weather, theft and relying on it to stay on. There is plenty of power available to have big batteries, chargers - everything needed and I can secure or hide that stuff.
As far as number of records/ time the system can run, is that Extech instrument the best there is? Or am I misunderstanding something?
