870B Baratron® Single-Ended Ultraclean Absolute Pressure Transducer and Local Display

Part Number: 870BProduct Details

Overview

Baratron® 800 Series transducers are ideally suited for use in delivery systems that feed ultrapure gases to critical process systems. Their wetted surfaces exposed to the gas stream have a finish better than 5 uin Ra. These transducers exhibit superior dry-down characteristics, and contribute no particles above background. After manufacture and assembly, they are purged with ultraclean nitrogen prior to double bagging.

The all-Inconel construction of the sensors in the Baratron® 800 Series transducers allows for high overpressure tolerances that reduce errors due to line pressure spikes. The 870 offers ±1% of Reading accuracy.

These transducers are suitable for use with SDS® (Safe Delivery Source) Systems.
Features

• Capacitance technology at a competitive price
• Industry's smallest integrated transducer with display <5"H
• Incoloy® wetted surface provides service superior corrosive gas and liquid compatability
• Rated for Class I, Division II service
• Highest overpressure ratio tolerances on the market assure no degradation in zero repeatability or performance
• Superior accuracy in lower pressure ranges vs competitive brands
• CE Mark compliant
• Optional NEMA 4 enclosure for outdoor
• 5 Ra finish (standard)
• Replaceable electronics
