ScanIR2 follows a logical convention - at least in terms of identifying the spectral response and basic specification. This was carried over to ScanIR3 but different to MP150 and MP based systems.
S213-12C20
S2 = Series 2 (ScanIR2)
1 - 1um spectral response
3 = 50Hz/1000 sample
12C = 1200 deg Celsius maximum measured temperarature
20 = optical resolution D:S/10
Note: This is a high level overview. In specifying a replacement system you will always need to take care about the finer points of the specification as later system do not replicate all functions and features.
Example 1:
The ScanIR2 processor can transmit ASCII process data directly to a control system via RS485
Later systems, can forward ASCII messages but only from the pc and not in the same format. However, later systems, via TCP/IP can transmit sector/zone results and also a scan line.
Example 2:
ScanIR2 can offer up to 5000 samples per line. ScanIR3 and MP150 based systems offer up to 1024 pixels. Samples are not really the same as pixels (Land also use this terminology). Depending on the application and the spot size, more samples simply equates to oversampling (overlapping measurements) and here there is always a case for "diminishing returns" discussion.
Example:
ScanIR2 states a specific D:S per model with a relationship between D:S. min measured temperature and scanner frequency.
ScanIR3 offers only one D:S version (as a standard product) where the manual depicts a D:S/scanningfrequency relationship.
Example 4:
ScanIR2 offered a 5um version starting at far lower temperature than is possible wiht ScanIR3 or MP150.
