These data loggers all have a pulse input. This will accept a volt free contact or transistor output from a flowmeter and allow you to log flow rates automatically. The SL7000 will also accept a 4/20mA output from a flowmeter. SL7000 Series – Universal Input Data Logger – Supplied with TempIT-Pro Software The SL7000 data loggers have a very flexible combination of inputs from a single temperature up to 4 universal inputs each of which can be individually configured to accept any combination of the following input types: - RTD / Pt100 - Thermocouple (Types J, K, T, R, S, B, N) (isolated tip) - mA (4-20mA 4/20mA) - Volts - mV - Thermistors - Slidewire - Cu - Ni
The SL7104 data loggers have an internal temperature sensor and a digital input which can be used as a trigger to start logging or as a pulse counter for interfacing with flow meters or other sensors with a pulse output. An optional internal relative humidity sensor with ±2% accuracy is available on all units as well as an optional external temperature and relative humidity sensor. This gives a total of 9 channels – internal temperature, internal pulse counter, internal relative humidity, external temperature & relative humidity and either two or four universal inputs.
