PD685 Intrinsically Safe IP67 Loop-Powered Meter

Brand: Precision Digital Corporation

The PD685 is an easy to use, loop-powered indicator, certified by CSA, ATEX and IECEx as intrinsically safe. 

The PD685 carries international certifications under both the Class/Division System and Zone System, and is thereby suitable for use in gas and dust hazardous areas worldwide.

The PD685 can be seen from considerable distance in bright sunlight or dimly lit areas when the standard backlight feature is activated. 

The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area. 

The meter gets all of the power it needs from the 4-20 mA loop and its 1 V - 4 V with backlight drop results in a minimal burden on the loop. 

The meter features a wide -40 to 75°C operating temperature range and is available with a ½" conduit hole in a location of your choice for easy installation. 

Calibration is a quick two-step process involving the adjustment of only two sets of coarse and fine, non-interacting potentiometers.
