Would this sensor be suited to measure the level of granular material in a bin, for example flour? The users manual only mentions liquid.

Asked by: Doctor Flour
Thank you for your inquiry about the level sensor. Unfortunately, it is only for liquids and the LR36, LR41, snd LR46 level sensor series can measure solids.

The user manual mentions ensuring the senser is compatible with liquids in the small tank its measuring, but does not define compatibility. Is this family of sensers compatible with soda-ash solutions (Sodium Carbonate) or sodium-hypochlorite solutions?

Asked by: TPUD
Thank you for your inquiry. Please note that chemical compatibility is the responsibility of custmers to check the media in question against the wetted materials of the produtc. As a courtesy, the sensor is made of PVDF and chemically compatible.

Can this device be set to fail high to 21 mA when looses contact with liquid surface or tank bottom? I've set it to do this but it never outputs 21mA.

Asked by: Beedoubleyou
Thank you for your inquiry! If the LVCN414-V is being used then this capability is not available. The voltage output models (-V) are only capable of the full, empty, or hold last loop fail-safe settings. With the standard current output models this overfill condition could be set to have the current output go to 21 or 22 mA when the return signal is lost.
