Failure to comply with these instructions could result in death or serious injury. Sensing and Control DCXL Series The DCXL line of ultra low pressure sensors is based upon SURSENSE , 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 SURSENSE 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.

Port 1 P1 Port: Dry Gases Only. Media must be compatible with epoxy based adhesive. Testing to Non Excitation Voltage Standard Conditions, Common mode pressure. Standard changes to: testing has positive pressure to port 2 with ambient pressure to port 1. Ratiometric Output: The output voltage of the sensor is ratiometric, proportional, to the excitation voltage. For this model sensor, all specifications will change proportionally to any changes in the excitation voltage. The excitation may vary between 3vots to 16 volts. All specifications will nominally be changed by a ratio of V EXCITATION/12.0 volts. For example: if the excitation voltage is 5.0 volts, then both the full scale output voltage and the offset voltage nominals would be 5/12th the specified value. Equivalent Circuit Pinout 1.
