AMWEI PTC NTC thermistors Temperature and Pressure Sensors has been widely applied in the field of telecom & network, HVAC & R, home electric appliance, white goods, food service, consumer electronics, lighting, office automation equipment, medical, automotive, consumer electronics, meter & instrumentation, data logger, power supply and transformer, industrial process control etc.

HVAC applications include indoor/outdoor air temperature, duct air temperature & water temperature, pressure sensing.

Thermistors sensors play a vital part in the efficiency of white goods by measuring and controlling the temperature of water, steam, air, food, as well as the electronic circuitry.

Thermistors can be found all around the home in washing machines, dishwashers, cookers, microwave ovens, irons, toasters, refrigerators and deep freezers.

Electronic sensors offer improved accuracy over electro-mechanical solutions and can be designed to perform over a wide range of temperatures and specifications.

Food service applications include food safety, and commercial cooking equipment.The food and drink dispensing industry requires precise pressure measurement in humid environments while maintaining sanitary conditions. AMWEI Temperature and Pressure Sensor can meet food and beverage service requirement.

Automotive applications include climate control, temperature and pressure sensing of fuel level, coolant & engine , and combustion controls, etc.

Compressors are used in a vast array of applications and are found in many industrial segments, including heat pumps, pipeline transport, railway vehicle equipment, pneumatic tools, refrigeration and air conditioners.
