We have a requirement to test a bed of up to 60 thermostats to determine and record the temperature at which each opens. The maximum temperature range over which we would sample is from 110C - 160C, however any specific test would span only +/- 20C.
Our preferred accuracy/resolution is 0.1C, but we could tolerate somewhat less precision. The thermostats will be in an oven with a rise time of 1C/min., so the sampling rate can be very slow (perhaps 6sec.). The temperature input will be from a 1K ohm platinum RTD (or a thermocouple would be ok).
For the digital (continuity) inputs, we would prefer to scan a 6X10 row-column matrix, but could provide a lead from each thermostat, if necessary. Therefore, we need either 16 or 60 digital inputs and one analog input. Data storage could be anywhere from 7,000 to 15,000 records (temperature/channel/state).
Can you offer a suggestion for your best hardware configuration to accomplish these requirements? Also, I’d like to know, if there are any software choices, which is preferred.
