Is there a temperature sensor for water with a connection to Cerbo GX?

Hi,

is it possible to set up an alarm if the temperature will reach a certain threshold? It would be very helpful for the deep freezer or the water heater.

Victron is working to make an interface to connect sensors that give 0-20 mA... then is everything possible. Search the forum for 20mA then you will find the post.

If this is a question about hot water tank temperature then I have potted LM335s in small metal tubes. Insulated the connection wires and filled them with epoxy like this.


They can then be inserted into the tank foam insulation or under the tank jacket and will give a reasonable value for the tank temperature. I use three to tell me the temperature at the top middle and bottom of the hot water tank and get a good estimate of how much hot water I have to take a shower.

Built this way the sensors are also robust enough to clamp to metal pipes or surfaces to give a temperature reading.

You could waterproof a LM335 sensor by using heat shrink tube with glue (probably easiest way) and place that on the bottom of the water tank/reservoir or in the water stream?

I want to check The temperature in outside tank for gray water

I would expect the temperature of the tank wall measured outside would be sufficient unless you have some special requirement ( or you are unable to access the tank wall)?

I would not immerse a sensor unless it is very well waterproofed.
