The TM-NT18 ceramic pressure sensor is a high-performance piezoresistive sensor manufactured using specialized ceramic substrate processes. Ceramic materials provide exceptional elasticity, corrosion resistance, wear resistance, shock resistance, and vibration tolerance. With thermal stability characteristics and high-temperature sintering processes, this sensor operates effectively within a temperature range of -40°C to 135°C, delivering high precision and stability. Featuring electrical insulation exceeding 2KV, this 18mm diameter sensor covers pressure ranges from 2 to 600 bar.

Widely used in process control, environmental control, hydraulic and pneumatic equipment, servo valves, series transmission systems, and medical instruments. Its superior corrosion resistance provides significant advantages in refrigeration, chemical processing, and environmental protection applications.

This corrosion-resistant ceramic pressure sensor operates without liquid transfer, with pressure acting directly on the ceramic diaphragm surface. Thick film resistors printed on the diaphragm back connect to a Wheatstone bridge, generating a highly linear voltage signal proportional to pressure and excitation voltage. Standard signals are calibrated to 2.0/3.0 mV/V depending on pressure range, ensuring compatibility with strain sensors. Laser calibration provides excellent temperature and time stability, while built-in temperature compensation allows direct contact with most media. The elimination of liquid transfer prevents contamination, making ceramic sensors increasingly preferred over strain and diffusion silicon pressure sensors.
