PD6870

PD8 ProtEX-MAX Series

The ProtEX-MAX Series are 1/8 DIN digital indicators mounted in explosion-proof housings. Include loop powered process meters, feet and inches level meters, and flow rate / totalizers in rugged NEMA 4X enclosures.However, the PD8 series is not just an 1/8 DIN meter mounted in an explosion-proof housing. A special bezel and electronics were designed exclusively for the ProtEX-MAX. The bezel and faceplate give the front panel a very finished appearance and house the additional electronics for the PD8. Program and operate the meter without opening the housing using the built-in SafeTouch® through-glass button programming on all units, or the serial communication port with free Modbus® protocol available on most units.

PD6801 ProtEX Explosion-Proof Feet & Inches Level Meter

The PD6801 explosion-proof loop-powered level meter displays level information in clearly labeled feet and inches. It the ideal level meter for hazardous areas, or safe areas in need of an extremely rugged solution. Its unique feet and inches LCD can indicate up to 399 feet, 11 and 15/16 inches.

A glance at the 20-segment tank level indicator conveys the level status in an instant. The 7-digit, easy to understand 14-sgement lower display can show a combination of custom tag, volume, or percent. Volume is calculated as a second scaling of the 4-20 mA input loop, and the percent display shows the tank full percentage as well as a PCT label to clearly identify the display as percent. Backlighting is standard, and the display is viewable in varying lighting conditions, from wide angles, and from a distance.

The PD6801 includes a modern, smooth, cast aluminum enclosure with two threaded conduit holes and integrated pipe or wall mounting holes. The operating temperature range is -40 to 75°C. Worldwide explosion-proof agency approvals include FM, ATEX, CSA, IECEx.

The ProtEX Super Snooper can be programmed as a Modbus RTU Master, Slave, or Snooper. As a Master, the scanner reads up to 16 slave devices, scales the data from each, and indicates each on an alternating display. The scanner in Master Mode is capable of polling up to 16 process variables (PVs). It shows each PV (PV1-PV16) alternately on the top and/or bottom display. In Snooper Mode, the scanner is able to read up to 16 variables being polled by the master by listening to the bus traffic.

The PD6830X scanners can communicate with any Modbus device using the ever-popular Modbus communications protocol. Take advantage of the Modbus capabilities in the level and flow transmitters you already have by using Master Mode to read more data, more accurately.
