Description

DPG409 Series Digital Pressure Gauge (DPG) with Analog Output and Optional Wireless Transmitter

 

Omega’s DPG409 Series incorporates a rugged 316 Stainless Steel enclosure that is designed specifically for wash-down, sanitary, and marine applications. The large backlit LCD display features 1″ high digits that make reading at distances up to 10.7 m (35′) easy. DPG models are available with integral standard or sanitary pressure sensors that incorporate highly-stable silicon wafer technology which is micro-machined to precision tolerances and then has strain gages molecularly embedded. Standard features include: internal battery or external DC power supply operation, analog output, and user programmable alarms. The wireless transmitter option allows for remote monitoring, chart recording and data logging. A variety of user-configurable options and settings include: update rate, dampening, units, backlight, and auto-off. Free Software for Set-up and Configuration via USB connection as well as Charting/Logging Software and drivers for wireless data.
