The ProtEX-Lite PD663 is a loop-powered field meter housed in an IP68, aluminum enclosure that is FM Approved and CSA Certified as Explosion-Proof, Dust-Ignition Proof, and Flame-Proof, and ATEX & IECEx Certified as Flame-Proof.
 
The PD663-SS is the stainless steel version of the ProtEX-Lite that is CSA Certified as Explosion-Proof, Dust-Ignition Proof, and Flame-Proof.
 
Both the PD663 and PD663-SS are easy to install and program, and they can be seen in a variety of lighting conditions, even in bright sunlight. The ProtEX-Lite meters will operate down to -40°C and the PD663-SS stainless steel version can be installed in areas where the temperature gets as cold as -55°C, however, the display will cease functioning.
 
The fact that these meters are loop-powered means that there is no need to run additional, costly power lines into a hazardous area. The meters get all the power they need from the 4-20 mA loop and their 1.7 V drop results in a minimal burden on the loop. Loop-powered backlighting is a standard feature that allows the meters to be read in dimly lit areas. The meters feature a wide -40 to 75°C operating temperature range and are available with two 1/2" NPT or M20 threaded conduit openings and flanges for wall or pipe mounting. Calibration is a quick process involving the four internal pushbuttons. The 3½+ digits display on the ProtEX-Lite will read up to 2999.
