WARNING
PERSONAL INJURY
DO NOT USE these products as safety or emergency stop devices or in any other application where failure of the product could result in personal injury.
Failure to comply with these instructions could result in death or serious injury.
The DCXL line of ultra low pressure sensors is based upon SURSENSEâ, a proprietary technology, which reduces all output offset or common mode errors.
These sensors use a silicon micromachined sensing element which features a unique stress concentration enhanced structure to provide a highly stable linear output that is proportional to applied pressure. Output offset errors due to changes in temperature, warm-up, long term stability and position sensitivity have all been significantly reduced when compared to conventional sensors.
The DCXL Series sensors provide a precision calibrated ratiometric millivolt output using the enhanced stability of SURSENSEâ technology. Each sensor features calibrated offset, full scale span and thermal error calibration to ensure the highest possible accuracy for flow pressure measurement. These highly stable sensors feature an industry standard ported package with improved stress isolation for printed circuit board mount applications.
Product is patented by US patent 6023978.
