Conductivity sensor SEN0451 with temp sensor: connection to data logger
Tim.Meeus 2024-07-27 04:57:46 4661 Views2 Replies Hi,
Is it possible to connect the conductivity sensor SEN0451 to a data logger (Titan S8).
Correct is I need to supply 5V to the sensor and need 2 analog inputs of the data logger for mV conductivity and mV temperature.
In the Arduino code, the code to calculate the raw conductivity and temperature can probably be found.
Temperature correction will probably need to be done afterwards.
Is it correct what I am saying? The data logger can also connect to temperature probes directly, would this be a better option and how should this be wired?
Thanks!
The Titan S8 can use its own temperature sensors (e.g., thermocouples or RTDs). However:
It may not give a precise temperature at the same spot as the conductivity sensor (which is important for compensation).
Also, SEN0451 has built-in temp sensing very close to the probe, which ensures accurate compensation. Using the SEN0451’s built-in temperature output is usually better, unless you can place the external probe exactly at the same position.
