PD663 ProtEX-Lite Explosion-Proof Loop-Powered Meter
Brand: Precision Digital Corporation
The PD663 is an explosion-proof loop-powered field meter that is available in an aluminum or stainless steel enclosure.
The ProtEX-Lite carries all major approvals including:
- UL Listed as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
- CSA Certified as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
- ATEX and IECEx Certified as Explosion-Proof
The PD663 is easy to install and program and the display can be seen in a variety of lighting conditions, even in bright sunlight. It will operate down to -40°C and is approved for installation in areas where the temperature gets as cold as -55°C, however the display will cease functioning.
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. Loop-powered backlighting is a standard feature that allows the meter to be read in dimly lit areas.
The meter features a built-in flange for wall or pipe mounting. Calibration is a quick process involving the four internal pushbuttons. The 3-1/2+ digits display on the ProtEX-Lite will read up to 2999.
