870B Baratron® Single-Ended Ultraclean Absolute Pressure Transducer and Local Display
Part Number: 870BProduct Details
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.
