PD685 Loop-Powered Digital Meter is Now ATEX Approved!
1 February 2018
The PD685 is now ATEX and IECEx approved as an intrinsically safe device for use in hazardous areas. The PD685 also has a new look, including a new LCD with larger and easier to read digits. This low-cost, NEMA 4X, loop-powered indicator is easy to install and program and can be seen from considerable distance. 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 the PD685’s 1 V drop results in a minimal burden on the loop. The meter features a wide -40 to 85°C operating temperature range and is provided 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 non-interacting potentiometers.
