DS18B20 Temperature Sensors
The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply.Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control system.

MZ6 Series Motor Protection PTC Thermistor
MZ6T PTC motor protection type thermistor is specially designed for over-temperature protection of motors and other parts according to international standards DIN-44081 and DIN-44082. The PTC thermistor is placed in the three-phase winding of the motor. When the temperature reaches the insulation level temperature, the resistance of the PTC rises, and the high-resistance signal is transmitted to the control protector, and the protector disconnects the motor line according to the signal to protect the motor.
