Introduction
The PD663 is a loop-powered field meter that is FM
Approved and CSA Certified as Explosion-Proof,
Dust-Ignition Proof, and Flame-Proof, and ATEX &
IECEx Certified as Flame-Proof and Protection by
Enclosure. The PD663 is easy to install and program
and it can be seen in a variety of lighting conditions
and even in bright sunlight. The fact that this meter is
loop-powered means that there is no need to run
additional, costly power lines into a hazardous area.
The meter gets all the power it needs from the
4-20 mA loop and its 1.7 V drop results in a minimal
burden on the loop.
The meter features a wide -40 to 75°C operating
temperature range and comes with two 1/2" NPT
threaded conduit openings and flanges for wall or
pipe mounting. Calibration is a quick process
involving the four internal push buttons. The PD663’s
display will read up to 2999; we call this 3½+ digits!
