Brooks Instrument SLA7840 Pressure/Flow Controller

About this part

SLA7840DZ140 is a configured Brooks Instrument SLA7840 identifier associated with the SLA7840 high-purity metal-sealed remote-transducer pressure/flow controller platform. Legacy Brooks-authored SLA7840 catalogue context identifies the model as a 1-1/8 inch pressure/flow controller that controls pressure while measuring flow rate and may be configured as a mass flow controller for calibration or test purposes. Stored Sonisys auction evidence for this exact configured code includes an N2 20 SLM, DeviceNet-context listing, but gas, range, valve, fitting, calibration, and interface details should be verified from the unit label or calibration record

Unit-specific configuration
Observed configuration

Historical listing records identify this part as N2 at 20 SLM. Exact gas, range, fittings, valve configuration, and communication interface must be verified from the physical unit label.

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

Specifications

Identification
Device typeHigh-purity metal-sealed remote-transducer pressure/flow controller
Series familyBrooks SLA7840 pressure/flow controller platform
Model roleLegacy SLA7840 catalogue context describes the model as controlling pressure from a remote pressure-transducer signal while also providing a flow-rate signal
Flow
SLA7840 family range contextLegacy SLA7840 catalogue context lists available ranges from 0-3 sccm to 0-30,000 sccm N2 equivalent; the exact configured range for SLA7840DZ140 must be verified from the unit label or calibration record
Configuration
Configured-unit ruleGas, full-scale flow, pressure-transducer range, fittings, valve behavior, calibration pages, power, and communication option vary by configured model code
Controls
Control and output contextSLA7840 model-level literature describes adjustable PID pressure control using a remote transducer signal and a flow-rate output signal; installed setpoint and network details must be confirmed from the exact unit
Communication contextSLA7840 model-level literature includes analog 0-5 V and DeviceNet communication contexts; use DeviceNet details only when the installed connector or label confirms that configuration
Applications
Application domainHigh-purity gas pressure and flow control in semiconductor gas-box, process, laboratory, and industrial gas systems
Observed variants
Stored auction gas/range combinationOne stored Sonisys auction title for this exact part records N2 20 SLM with DeviceNet context; this is observed listing evidence, not an official stock specification
