a.Product description
TM-NT18 ceramic pressure sensor is a kind of ceramic piezoresistive
pressuresensor 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, hydraulicand pneumatic equipment,
servo valves,Series transmission, and medical instruments.it
corrosion resistance makes
it have great advantages in refrigeration, chemical and environmental
protection.

C. PRINCIPLES OF WORK
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 var istor, 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.

F. 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.
