KP46 - Explosion-Proof Pressure Transmitter

Brand: KOBOLD Instruments, Inc

The KOBOLD KP46 explosion-proof pressure transmitter is approved for use in hazardous locations per CSA Standard 30 and UL® Standard 1203 for Class 1, Division 1 and Division 2 hazardous locations. 

Wetted parts are all 316L Stainless Steel (50 up to 10000 PSIG), 17-4PH (15000 & 20000 PSIG) for compatibility with a variety of media. 

Wetted materials and construction comply with the NACE MR0175 Standard. 

The KP46’s fitting and sensing diaphragm are machined out of a single piece of material, so there are no welds, seams or O-ring seals, resulting in excellent long-term performance and stability. 

The case is factory sealed, making this pressure transmitter very rugged with excellent shock and vibration resistance. 

The KP46 is perfect for explosion-proof applications where both price and performance are critical.
