Introduction
The DLLR Series Mini Digital Output Sensor is based on
All Sensors’ CoBeam2 TM Technology. This reduces package
stress susceptibility, resulting in improved overall long term
stability and vastly improves the position sensitivity.
The digital interface eases integration of the sensors into a
wide range of process control and measurement systems,
allowing direct connection to serial communications chan-
nels. For battery-powered systems, the sensors can enter very
low-power mode 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, dry gases.
