AMWEI Thermistor Sensor design and manufacture PTC & NTC thermistors (THERMally sensitive resistors), thermistor temperature sensors probe, as well as Ceramic Capacitive Pressure Sensors Transducers.
PTC (Positive Temperature Coefficient) thermistor application covers over-current & overload protection, telecom, lighting switching, motor starting, temperature sensing & protection, self-regulation heating, linear PTC thermistor, silicon temperature sensor.
NTC (Negative Temperature Coefficient) thermistor application covers power thermistor for inrush current suppressing limiting, NTC thermistor for temperature measurement, indicator, temperature compensation, temperature control, in either radial leaded, axial leaded construction. Can also make custom thermistors assemblies and temperature probes, housed in either stainless steel, copper, plastic, teflon, aluminum, epoxy and heat shrinkable tubing, such as air/gas temperature sensors, surface temperature sensors and immersion temperature sensors, etc.
AMWEI Dry type Ceramic Capacitive Pressure Sensors Transducers compatible to gas oil liquid media, for compressor, refrigerator, industrial process, building equipment,transportation, food & beverages, medical, test and measurement application.
The 2 founders of AMWEI Thermistor came from Nonmetal Material Research Institute of Huazhong University of Science and Technology, once as a visiting scholar in Japan in late 1980, and took charge of Chinese first imported PTC production line. Thorough successive hard work of a group of specialists in ceramic sensitive material, welding technology, packaging technology, we own core know-how in powder formula and key production technics.
Our NTC thermistor features with high accuracy, fast response and long time stability.
PTC thermistors switch life and voltage withstanding capacity is leading in China.
Using robust, reliable and media resistant Ceramic Capacitive Sensing Technology, AMWEI dry type pressure sensors are designed for harsh environment, with superior EMI protection, high overpressure capability, outstanding shock and vibration performance, and exceptional long term stability, specially features with positive and negative pressure measurement function, such as ±10kpa, ±1kpa, etc.
We maintain the highest quality standards through continuous employee training, rigorous internal auditing. We take continuous improvement as a primary business objective. SPC, MSA, 6-Sigma techniques are being applied throughout the manufacturing process in an endless loop of quality improvement.
ISO9001:2000 certified in 2003.
