Introduction
The DLC Series Compact High Resolution Sensor is based on
All Sensors’ CoBeam
2 TM
Technology. This reduces package
stress susceptibility, resulting in improved overall long term
stability. This technology breakthrough advances the state of
the art for piezoresistive pressure sensors beyond what has
been achieved for low pressure sensing using silicon based
strain technology. Design engineers will find exceptional
space savings with optimal performance for various compact
applications.
The low supply voltage allows for integration of the sen-
sors into a wide range of process control and measurement
systems, as well as direct connection to I2C serial com-
munications channels. The DLC series offers 16 bit digital
resolution. The digital interface options ease integration
of the sensors into a wide range of process control and
measurement systems, allowing direct connection to serial
communications channels. For battery-powered systems, the
sensors can enter very low-power modes between readings
to minimize load on the power supply.
These calibrated and compensated sensors provide accurate,
stable output over a wide temperature range. This series
is intended for use with non-corrosive, non-ionic working
fluids such as air and dry gases.
