5850EC4BE4NB2A
Brooks Instrument 5850E Mass Flow Controller
About this part
5850EC4BE4NB2A is a configured Brooks Instrument 5850E Series thermal gas mass flow controller identifier observed in Sonisys auction history. Official Brooks 5800E/5850E documentation verifies the 5850E as an elastomer-sealed analog gas mass flow controller platform; gas, full-scale range, process fittings, connector, valve state, and seal package remain configured-unit details that should be verified from the physical unit label or calibration paperwork
Configurations vary. Verify the exact unit before choosing a replacement.

Specifications
Identification
| Part identifier | 5850EC4BE4NB2A |
| Device type | Thermal gas mass flow controller |
| Series family | Brooks 5800E / 5850E elastomer-sealed analog gas mass flow controller series |
Configuration
| Configured-unit rule | Gas, full-scale range, process fitting, connector, valve state, and seal package vary by configured model code and physical unit label |
Function
| Control architecture | Official 5850E documentation describes a flow sensor, control valve, and integral electronic control system used to produce stable gas flow |
Flow
| 5850E standard range context | Brooks 5850E documentation lists standard ranges from 3 sccm to 30 slpm nitrogen equivalent |
Performance
| 5850E accuracy context | +/-1% full scale including linearity at calibration conditions; +/-1.5% full scale for flow ranges greater than 20 slpm |
| 5850E repeatability context | 0.25% of rate |
| 5850E response time context | Less than 3 seconds to within 2% of full-scale final value for a 0 to 100% command step |
| 5850E control range context | 50:1 |
Pressure
| 5850E working pressure context | Official 5850E documentation lists 1500 psi maximum working pressure |
| 5850E differential pressure context | Official 5850E documentation lists 5 to 50 psi differential pressure, with minimum pressure drop depending on gas and range |
Environmental
| Operating temperature context | 40 F to 150 F (5 C to 65 C) |
Electrical
| 5850E command input | 0-5 Vdc command input with 200 k ohm input resistance |
| 5850E flow output | 0-5 Vdc output into 2000 ohms or greater |
| 5850E connector options | Card-edge connector or 15-pin D-connector (DA-15P), depending on configuration |
Materials
| 5800E wetted-material context | Official 5800E data-sheet context lists 316L stainless steel, high-alloy stainless steel, Viton fluoroelastomers, Buna-N, Kalrez, and Teflon among primary wetted materials, depending on configuration |
Leak integrity
| External helium leak integrity | Official 5850E documentation lists 1 x 10^-9 atm cc/sec helium leak integrity |
Mechanical
| Process connection context | Official 5850E documentation lists 1/4 inch compression fittings for flow rates up to 10 slpm, 3/8 inch compression fittings for higher flow rates, and optional VCO and VCR connections |
Controls
| Valve override | Official 5850E documentation describes valve override for fully opening or closing the control valve independent of command setting |
| Soft start | Official 5850E documentation describes soft start as a flow-ramping function for processes that cannot tolerate rapid flow transition |
Applications
| Application domain | Semiconductor, laboratory, analytical, chemical and petrochemical research, fuel-cell, life-science, and general gas-flow applications |
