I remember when doing stress relief we used special compensating cable between the sensor and the controller. Do these sensors the NTC 25ºC=10K B3435 ±1% quote from operation instructions need special cable or can I use simple bell wire, and same with plugs and sockets do I need special or will anything do?
Also running two controllers on the same batch of beer one for heating and one for cooling, can I use same sensor for both or do I need one each? If one each can a common one cable so using three core rather than 4 core?
I use them to brew beer, in the summer months one controller a STC 1000 controls heating and another a MH1210A the cooling which gives me three differentials so I get.
18ºC heating starts.
18.3ºC heating stops.
20.0ºC cooling starts.
20.1ºC cooling stops.
With a 15 minute delay before cooling starts.
I can't use a single controller as with the STC1000 the 0.3ºC differential is universal so measuring the fermentor (and I am not really interested what the temperature of the freezers air is.) the fermentor drops more that 0.3ºC each time the motor starts, so heating then comes on even in the hot days. So I have to use both controllers, I would like to reconfigure them all into one box, although the STC1000 has two relays in real terms can't use both so may as well combine both units together. Would like to extend cables so I can monitor from computer room. Hence the question.
