The PM620LP is the new low-pressure module within the PM620 range. The PM620 series is the latest development in digital output sensor technology, incorporating a number of key innovations to allow pressure re-ranging of compatible equipment. The PM620 series utilizes a simple screw fit for both pressure and electrical connections, eliminating the need for tools, sealing tape, cables, or plugs. Additionally, digital characterization enables interchangeability without the need for setup or calibration.
Used with the PV624 pressure controller. Ranges from 2.5 mbar diff to 25 mbar diff (1 to 10 inH2O diff), with total uncertainty from 0.05% Span. The PM620LP has a true differential measurement via a fitted barbed low pressure (LP) connector and is supplied with 1 x barbed high pressure (HP) connector to fit a PV624 test port, 1 x equalizing valve, and 1M (3.3 ft) length of silicon twin tubing.
Features• Ranges from 2.5 mbar differential to 25 mbar differential (1 to 10 inH2O diff)
• Total uncertainty from 0.05% Span
