The PD683 is designed for demanding process control applications. Standard features include a full 5-digit backlit display with bargraph, on-screen custom engineering units, and max/min display capabilities. There are two models available: the PD683 is for general-purpose applications and the PD688 is for hazardous area applications. Even with all the features packed into these meters, they’re still easy to setup and get running. Everything is programmed from the front panel buttons with no pots or jumpers to deal with. In fact, these indicators can be scaled without a signal source for even quicker setup. The PD683 and PD688 go just about anywhere with their shallow-depth case, FM Type 4X front, loop-powered backlighting, and wide operating temperature range. It doesn’t matter if they’re indoors or outdoors, in bright sunlight, or a dimly lit plant, wet, dirty, hot or cold. And the PD688, with its FM approval and CSA certification, can be installed in just about any hazardous area environment. Square root and programmable exponent functions are standard features on the PD683 and PD688. With these features these indicators can display flow from a DP transmitter or open channel flow in weirs and flumes.
