NTC Thermistor 3950 1% NTC 10K Temperature Sensor Refrigeration Air Conditioner Refrigerator 1 M 10k Tthermistor Probe
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.
Automotive applications generally use wafers, glass encapsulated wafers or Uni-Curve™ products for temperature monitoring and control of airflow and immersion applications. These devices are commonly used as air intake sensors, battery, engine and transmission temperature sensors, air conditioning and interior/exterior ambient temperature sensors, and oil and gas level sensors.
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.
Telecom applications typically use ntc temperature sensors for temperature compensation or glass-encapsulated wafers for temperature monitoring and control. Typical applications include switchgear, and rechargeable NiCad and NiMH batteries on cordless phones, radios, and pagers for charge control.
Military/Aerospace applications require the use of precision wafer or glass bead assemblies to monitor the temperature of aircraft, satellites, ground-based radars, manned orbiters, and deep space sounding rockets.
