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. The standard accuracy of this series is ‑+0.5% FSO but is offered with ‑+0.25% and N.I.S.T. certification as well (see expanded series). Field selectable analog outputs include 0‑5 and 0‑10 VDC, or 4‑20mA which correlate to a uni or bidirectional pressure range from 0‑0.1" up to 0‑40" of water column, depending on your model selection. Each unit has up to 8 field selectable, uni or bidirectional ranges. Options include a Pitot Tube or Din Rail Clip.
