5850EC4BL4XB2A

Brooks Instrument 5850E Mass Flow Controller

About this part

5850EC4BL4XB2A is a configured Brooks Instrument 5850E thermal mass flow controller code retained from Sonisys auction history. The 5850E family is an elastomer-sealed analog gas mass flow controller platform with 0-5 Vdc command and flow output, removable/cleanable sensor design, soft-start and valve-override functions, and flow ranges up to 30,000 sccm nitrogen equivalent. Exact gas, full-scale range, fitting, valve state, connector, and seal materials must be verified from the unit label or calibration paperwork

Configurations vary. Verify the exact unit before choosing a replacement.

Specifications

Identification

Device type	Thermal mass flow controller
Series family	5800E / Model 5850E Series
Configured code	5850EC4BL4XB2A is a configured 5850E model code; the suffix encodes build options that should be verified from the unit nameplate

Configuration

Configured-unit rule

Gas, full-scale range, fitting, valve state, connector, and seal package vary by configured model code

Flow

5800E flow range context

5850E data-sheet coverage spans any range from 0-3 sccm to 0-30,000 sccm nitrogen equivalent depending on calibration and configuration

Performance

5800E accuracy context	5800E data-sheet accuracy is +/-1% full scale including linearity at calibrated conditions, with higher-flow variants specified separately
5800E repeatability context	5800E data-sheet repeatability is 0.25% of rate
5800E control range context	5800E data-sheet control range is 50:1

Pressure

5800E maximum operating pressure context	5800E data-sheet maximum operating pressure is 1500 psig; pressure drop depends on gas and range
Pressure sensitivity	+/-0.03% per psi up to 200 psig for N2 in the 5850E data sheet

Environmental

5800E temperature context

5800E data-sheet ambient/gas temperature range is 5 C to 65 C

Materials

5800E wetted-material context

5800E data-sheet wetted materials are stainless steel with Viton standard and Kalrez or Buna-N optional

Leak integrity

Outboard helium leak integrity

1 x 10^-10 atmosphere cc/sec helium

Mechanical

5800E process connection context

5800E data-sheet standard process connection is 9/16-18 UNF with stainless steel compression fittings; VCO and VCR are optional

Electrical

5800E command input	5800E configurations use 0-5 Vdc command input
5800E flow output	5800E configurations use 0-5 Vdc flow output into a suitable load
5800E connector options	5800E data sheet lists card-edge connector and D-type DA-15P connector options
Power requirement context	Normally closed valve configurations require +/-15 Vdc power; exact current draw depends on valve and flow-range configuration

Controls

Valve behavior context	5800E controllers use a precision solenoid control valve; valve override can hold the valve fully open or closed
Soft start	5850E supports a soft-start flow-ramping function for processes that cannot tolerate rapid flow transition

Applications

Application domain

Semiconductor, laboratory, analytical, and process gas handling
