Explosion-Proof Pressure Transmitter Model KP46

Description

The KOBOLD KP46 series explosion-proof pressure transmitter is
approved for use in hazardous locations per CSA standard 30 and
U.L. standard 1203 for Class 1, Division 1 and 2 locations. The
wetted materials are 316L or 17-4 PH stainless steel for compatibility
with a wide variety of media. Both materials and construction comply
with NACE MR0175. Other wetted materials, such as Hastelloy®
C276 and Inconel® 178, are available upon request. The fitting and
sensing diaphragm are machined out of a single piece of material
so there are no welds, seams, or o-ring seals. This design results
in excellent long-term performance and stability. The case is factory
sealed, making the KP46 series very rugged with excellent shock and
vibration resistance. It is ideal for explosion-proof applications where
both price and performance are critical.
