Temperatur probe pt1000 make mt tank go crazy

[GUPSTER]

profilux 3.1 ex
My temperature management went perfectly But now my temperature sensor is upset .. temperature suddenly rises according to the profilux but my temp in the tank drops .. Then I adjust the temperature in the profilux according to my analog thermometer and then the temp drops again at night, then the profilux controls the heating element.. while the tank is at temp, so it gets warmer.. do you ever have this had to deal. ? Would the sensor be broken or would the profilux no longer be fresh?

Plss help

Hello,

Sorry for that, but i guess sensor may be a little old.
The sensor may be broken yes, check also the wiring, there may be a bad contact at the connection.

Do you know how much Ohm te probe should have
Wen masure the probe is like 650 Ohm at 25 degrees
I brought a New one but its a BNC connector. That 1 is like 1100 Ohm .. was hoping there the same so i could change connector.

New from where?

GHL temperature sensors with BNC connector are not PT1000 but digital chip.

Hello,

Never edit calibration values of the temperature sensors:

New probe installed ad 18.30
Start temp 24.5 the powerbar is working so my heater is now 1 hour on real tank temp is 25 now but the profilux say my tank is 23.4 and still keep my heater on.. i see the temp. Still Lowering on the profilux
Looks like my profilux is not working correct any more.
New probe works the same as the old probe..
Wen installed probe i keep the New probe away from any other powercords.. so there is no interverens13420

Now i use the option on the profilux.
Fix dig. Temperature sensor issue
And correct the temp. Conform my analoge tempature.
What can i do more?

[Gael]

Could the temperature port or the electronics inside the ProfiLux have gotten wet, got humidity or splashed?
Are all other sensors working properly?
I think it is best to open a support ticket and attach pictures.

PS: Never use "Fix dig. Temperature" with analog temperature sensor like PT1000.
