They can operate on their own or synchronized with vibration FFT spectral collectors or even external tachometers.
Some models allow pulse output and input (TTL compatible) via BNC connection. Among the different models of the PRE2300 series:
- PRE2320: range up to 10,000 FPM. No TTL pulse input or output.
- PRE2322: range up to 20,000 FPM. TTL pulse input and output.
- PRE2324: range up to 50,000 FPM. TTL pulse input and output.
- PRE2325: range up to 12,500 FPM. TTL pulse output and input and possibility to work in external and internal mode.
- PRE2330: range up to 50,000 FPM. TTL pulse output and input for portable FFT collectors.
