Hi,

I have a question about how long an extension one can get for the level and/or temperature sensors. We would like to monitor the level and temperature of an external 5000 l header tank but this is, unfortunately, more than 5m away from the profilux control unit (3N Ex). It is possible to connect 2 of the 5m extension cords to make a single 10m cable or would that attenuate the signal too much?

Also, regarding the level sensor - what is the dynamic level of the optical and float sensors? Can I measure a level change of a meter or so? We have an opaque plastic 5000 l (2.5 m high) tank as a store/pretreatment and we would like to monitor the level to ensure that the downstream system doesn't get starved of water so would like to sense when the water is about 1 m from the top. Is this possible with either sensor?

Thanks,
Dave
