Precision Digital has introduced their PD685 NEMA 4X Loop Powered Digital Process Meter. The PD685 offers effortless installation and programming. The need to run extra, costly power lines into a harmful area is now eradicated as the meter is powered from the 4-20 mA loop, while the 1V drop produces less of a burden on the loop. The vast -40°C to 85°C operating temperature range suits an array of applications and the ½” conduit hole in the user designated location makes installation effortless. More still, calibration is quick and easy requiring only the adjustment of two non-interaction potentiometers.
