Simple constant temperature controllor circuit composed of 555

Published:2011/8/9 2:17:00 Author:Rebekka | Keyword: Simple , constant temperature controllor

Rt1 contacts the contact because of the heated expansion, but IC 6 feet is disconnected since the Rt2 is still at the low level, thus the trigger circuit skins. The temperature continue to rise to the upper limit value, Rt2 is conducted, the corresponding 6 feet potential is inhigh level (6 V), it is larger than 6 x two-thirds = 4 V trigger level. The IC resets, the (3) foot outputs low level, SCR stops and the electric heating wires power supply is disconnected. It stops heating. When the temperature drops, Rt2 will be disconnected. For 555 circuit is self-preservation and it still outputs low level feet by (3). When the temperature drops to the limit value, Rt1 is disconnected.   (View)

Developer temperature control circuit diagram

Published:2011/8/9 2:13:00 Author:Rebekka | Keyword: Developer temperature control

The figure shows the developer temperature control circuit. When the power supply is open, the temperature is low, the value of the R1 is high, so that the 5G31 outputs high level because the input potential of the positive end is higer than the input potential of the negative end.The relay J suck closes, RL starts to heat because the power supply is open and makes the temperature high. When the temperature rise to the control temperature, the bridge turns to balance. The 5G31 outputs low level because the potential of negative input terminal is higher than the positive input terminal . The relay J is disconnected, RL stops to heat because the power supply is closed.   (View)
