The Precision Digital PD685 is a reliable digital indicator designed for hazardous environments. It meets ATEX and IECEx safety standards and is rated IP67 for water and dust resistance. This loop-powered device is simple to install and program, making it a great choice for various applications.
One of the standout features of the PD685 is its visibility. Whether in bright sunlight or low-light conditions, the display remains clear, especially when the backlight is turned on. This ensures you can read measurements from a distance without any hassle.
Since the PD685 is loop-powered, there’s no need to install extra power lines in hazardous areas, saving you time and money. It draws all the power it needs from the 4-20 mA loop, with a minimal voltage drop of just 1 V (or 4 V with the backlight). This design keeps the burden on the loop low.
With an impressive operating temperature range of -40°C to +75°C, this meter is built to perform in extreme conditions. Installation is straightforward, thanks to a 22 mm (0.865″) conduit hole that can be placed wherever you need it.
Calibration is quick and easy, requiring only a simple two-step process. You’ll adjust two sets of coarse and fine potentiometers, which do not interfere with each other, making it user-friendly.
