ProtEX-Lite Explosion-Proof Loop-Powered Process Meter (PD663)
Manufacturer: Precision Digital
 
Starting at: $379.00 (USD)
Delivery: 1 to 2 weeks
Description



The PD663 is a rugged, explosion-proof NEMA 4X loop-powered meter perfect for applications where a simple, inexpensive display is required in a hazardous area.


The PD663 derives all its power from the 4-20 mA loop. The PD663 is scaled using four push buttons and can be done without applying an actual calibration signal, and through the explosion-proof enclosure with optional magnetic reed switches and a magnet key. The PD663's display will read up to 2999; we call this 3+ digits! The loop-powered backlighting option lets you see the display under any lighting condition and is powered completely from the 4-20 mA loop. This means there is no need for additional wiring and never any batteries to change.
