Factory configured to a 1 inWC span at 0.25% accuracy, this differential pressure transmitter suits filter monitoring, duct static pressure and air flow measurement where the range is known and fixed. An LCD reports the reading locally, and the piezoresistive silicon sensing element holds its calibration across the full working range.
Factory configured to a 1 inWC span at 0.25% accuracy, this differential pressure transmitter suits filter monitoring, duct static pressure and air flow measurement where the range is known and fixed. An LCD reports the reading locally, and the piezoresistive silicon sensing element holds its calibration across the full working range.
The DLP Series is based on a piezoresistive, silicon sensing element which senses Differential Pressure and provides an analog output. The hinged cover on the DLP can be easily opened using the integrated locking tab on the side of the enclosure. This allows for easy access to the zero function and field selectable ranges and outputs. The DLP Series also includes an optional, five digit LCD for installation and monitoring support.
