Intelligen,t Bullet Electric Temp Sensor Resistance B-Value Can Be Customized
NTC temperature sensor is a kind of thermistor and probe. Its principle is: the resistance value drops rapidly as the temperature rises. It usually consists of 2 or 3 metal oxides, mixed in a fluid-like clay, and calcined in a high-temperature furnace to form a dense sintered ceramic. Actual size is very flexible, they can be as small as 0.010 inches or very small diameter. There is almost no limit to the maximum size, but usually under half an inch applies.
Principle
Using NTC thermistor under a certain measurement power, the resistance value drops rapidly as the temperature rises. Utilizing this feature, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, so as to achieve the purpose of detecting and controlling the temperature.
►Design considerations and procedure of temperature sensor:
1. Choose the shape acoording to customer's design or assemble requirements, and confirm the thermistor.
2. Confirm the thermistor element and other materials according to customers' requirement
3. Choose the suitable resistance,B value and tolerance
4. Choose suitable moisture-proof and insulation technology to meet customer's requirement
5. Choose suitable encapsulation structure to meet performance requirements of mechanical shock resistance
6. Meet customer's special requirements.

Application of ntc temperature sensor
Medical applications: It is generally necessary to use ntc temperature sensors in digital thermometers, culture (incubator) boxes, skin sensors, urinary catheters, dialysis equipment, and respirators to monitor temperature, blood flow, or airflow.
Appliance Applications: Generally use glass encapsulated wafers in various packages to monitor and control ovens, microwave ovens, washers and dryers, dishwashers and small appliances - toasters, blenders, hair dryers, curling irons, showers , air conditioners, stoves, refrigerators, freezers and temperature monitoring on rechargeable NiCd and NiMH batteries, charging control for cordless power tools and appliances, camcorders, portable CD players/radios.
Office automation/data processing applications generally use ntc temperature sensors for temperature monitoring and control of strapping machines, overhead projectors, color printers, copiers, central processing units (hosts), power supplies, and laptop computers, personal organizers and Charge control for rechargeable NiCad and NiMH batteries used in other battery powered portable equipment.
