US
The PT-405 Explosion Proof, Heavy Duty Pressure Transducer gives you reliable accuracy in harsh conditions and
hazardous locations. With a CSA certication for Class I, Division 1, Explosion Proof locations, an IP65 rated sensor
body, and single seal construction for the highest safety factor, the PT-405 can survive in rough environments. With
a standard accuracy of 0.25% BFSL, and NIST certicates available for 0.5%, 0.25%, and 0.1%, the PT-405 is sensitive
enough to give you precise pressure measurements over its 30,000 psi range. Durability, reliablity, and sensitivity,
all in one tough little package.
