Brooks Instrument 5800E Series Nitrogen Mass Flow Controller
About this part
5850EC4BF3RB2A is a configured Brooks Instrument 5850E / 5800E Series elastomer-sealed analog thermal mass flow controller identifier. Stored Sonisys auction records and listing records references identify the observed unit context as a nitrogen mass flow controller associated with seller reference T258187. Official Brooks 5800E and 5850E documentation provides the family-level operating, electrical, and performance context, but the exact full-scale flow range, fittings, valve state, seal package, and calibration should be verified from the physical unit label and calibration records
Unit-specific configuration
Observed configuration
Historical listing records identify this part as Nitrogen. Exact gas, range, fittings, valve configuration, and communication interface must be verified from the physical unit label.

Thermal mass flow measurement with precision control-valve regulation for gases
Configuration
Observed gas context
Stored and listing evidence identifies the observed unit context as nitrogen; the exact full-scale flow range was not found in the available title evidence
Configured-unit rule
Gas, full-scale range, pressure drop, fittings, seal package, valve behavior, connector, power wiring, and calibration are unit-specific and must be read from the physical label and calibration records
Flow
5850E model range context
Brooks 5850E documentation lists standard ranges from 3 sccm to 30 slpm nitrogen equivalent; the exact range for 5850EC4BF3RB2A must be verified from the unit
Performance
Accuracy context
Brooks 5850E documentation lists +/-1% full scale including linearity at calibration conditions, with +/-1.5% full scale context for flow ranges greater than 20 slpm
Repeatability
Brooks 5850E documentation lists repeatability as 0.25% of rate
Response time
Brooks 5850E documentation lists response to within 2% of full-scale final value in less than 3 seconds for a 0 to 100% command step
Control range
Brooks 5850E documentation lists a 50:1 control range
Limits
Working pressure context
Brooks 5850E documentation lists 1500 psi maximum working pressure; verify the pressure rating and pressure drop for the exact configured unit
Differential pressure context
Brooks 5850E documentation lists 5 to 50 psi differential pressure context, with minimum pressure drop depending on gas and range
Operating temperature context
Brooks 5850E documentation lists operating ambient temperature from 40 F to 150 F / 5 C to 65 C
Materials
Wetted-material context
Brooks 5800E documentation identifies 316L stainless steel, high-alloy stainless steel, Viton, Buna-N, Kalrez, and Teflon wetted-material context depending on configuration
Electrical
Analog command and output
5850E configurations use 0-5 Vdc command input and 0-5 Vdc flow output context
Power context
5850E documentation lists +/-15 Vdc supply context, with current draw depending on normally closed or normally open valve configuration
Connector context
Brooks 5850E documentation lists card-edge and 15-pin DA-15P D-connector options; verify the connector on the specific unit
