| The Model DA is a controller for the monitoring of low differential pressures. |
| DK RHThe Model DA is a controller for the monitoring of low differential pressures. It combines in one enclosure a low pressure transducer, a digital display and up to two alarms. It is typically used for the monitoring of clean room pressures, duct static and velocity pressures, as well as filter differential, draft, fume hood and other low pressure applications.
The pressure sensing element is a differential capacitance cell for pressure measurements ranging from 0.1 to 10.0 inches of water (25 Pa to 2.5 kPa), or a piezoresistive (silicon) sensor for pressures from 10 inches of water to 30 psi (2.5 kPa to 200 kPa). The display section has 3-1/2 digits with bright, easy to read LED's. The display is factory-calibrated to read in engineering units.
The alarm section is offered with 1 or 2 alarms.
Barb fittings ( 3/16" O.D.) and pluggable terminals with screw clamps are provided at the rear for quick and simple field connections. |
