AVT611 B

The thermal alarm / temperature controller system uses a thermistor as a sensor. He works in a bridge system. The measurement signal is amplified and fed to a comparator with hysteresis. The kit uses a double, integrated operational amplifier LM358. The transistor output stage allows the use of various types of actuators: relay, buzzer, optotriac, etc. The system is surprisingly simple, easy to assemble and reliable in operation.
The kit is realized on the PW03 multifunction board, which should be purchased separately .

The device is recommended to electronics-experimenters and anyone who wants to control the temperature

Selected parameters:

• the temperature drop is signaled by the change of the output state
• the system can act as a thermal alarm
• full-value temperature regulator
• possibility of cooperation with various executive elements
• power supply - 6-15 V
• set of elements and documentation included
• Detailed description in EdW 7/04

Attention!!! The PW03 PCB should be purchased separately.
