Product Description

0~100bar resistance ceramic pressure sensor use for car A/C systerm Auto Sensors


Product description
TM-NT18 ceramic pressure sensor is a kind of ceramic piezoresistive pressure sensor which is refined by special process using ceramic base. Ceramic is a recognized material with high elasticity, corrosion resistance, wear resistance, shock resistance and vibration. The thermal stability characteristics of ceramics and the high temperature sintering process of thick film make the working temperature range of ceramic pressure sensor up to -40~125℃. and has high precision and high stability. More than 2 KV electrical insulation, its size diameter 18 mm, range 2-400 bar.. ceramic pressure sensors are widely used in the fields of process control, environmental control, hydraulic and pneumatic equipment, servo valves, transmission, and medical instruments.its corrosion resistance makes it have great advantages in refrigeration, chemical and environmental protection.


● High elasticity ceramic sensitive diaphragm Calibration ● zero point and full range laser ● Excellent corrosion and wear resistance ● shock and vibration resistance ● High sensitivity, high precision, high stability ● wide operating temperature range ● Small size, easy to package ● very competitive
The corrosion-resistant ceramic pressure sensor has no liquid transfer, and the pressure acts directly on the front surface of the ceramic diaphragm, resulting in a small deformation of the diaphragm. The thick film resistance is printed on the back of the ceramic diaphragm and connected to a Wheatstone bridge (closed bridge) due to the piezoresistive effect of varistor, the bridge generates a highly linear voltage signal proportional to the pressure and proportional to the excitation voltage. the standard signal is calibrated to 2.0/3.0 according to the different pressure range mV /V, which can be compatible with the strain sensor. by laser calibration, the sensor has high temperature stability and time stability. the sensor comes with temperature compensation and can be in direct contact with most media. Because ceramic pressure sensors can contact with most media, there is no direct transfer of liquid, and no pollution, the trend of replacing other types of sensors in Europe and the United States is becoming more and more obvious, and more users in China are using ceramic sensors instead of strain and diffusion silicon pressure sensors

VIII. Use considerations:
1. the core is installed, nylon washer should be installed on the lead surface of the core to make the core force uniform and avoid zero point instability. Before 2. the welding lead, please preheat the core body, increase the solderability of the solder joint, avoid the solder joint heating for a long time to reduce the adhesion of the pad. For welding, use no more than 60 W of tip soldering iron. 3. the black film part do not touch, scratch the black film will damage the internal circuit, damage the sensor
