Flow Control
5866A1Z1075
Brooks Instrument 5866 Pressure Controller/Flowmeter
About this part
5866A1Z1075 is a configured Brooks Instrument 5866-family pressure-control flow device observed in stored auction records as a mass flow controller. Official Brooks 5866RT documentation describes the family as a pressure controller/flowmeter that controls upstream or downstream pressure from a remote pressure transducer while also measuring mass flow through the control valve. Exact gas, range, valve behavior, seal package, fitting, pressure-transducer interface, and calibration details must be verified from the complete model code and physical label
Configurations vary. Verify the exact unit before choosing a replacement.

Specifications
Identification
| Configured part number | 5866A1Z1075 |
| Device type | Configured Brooks 5866 pressure controller/flowmeter |
| Series family | Brooks 5866 / 5866RT pressure controller and flowmeter family |
Function
| Pressure-control function | Maintains a desired upstream or downstream pressure by comparing a remote pressure transducer signal to the setpoint and modulating the integral control valve |
| Flow-measurement function | Measures mass flow through the control valve and provides a 0-5 V signal proportional to mass flow |
| Mass-flow-controller mode | The Brooks 5866RT platform can be configured as a mass flow controller for calibration or test purposes |
Pressure
| Control architecture | Remote pressure sensor input with adjustable integral PID control electronics and control-valve modulation |
| Remote pressure sensor compatibility | Suitable for pressure sensors with 0-5 V or 0-10 V output signals |
| Pressure-control range | 100:1 when used with a remote transducer that has a 0-10 V output |
| Pressure response time | Less than 0.8 seconds typical for a 0-100% command step with less than 2% pressure overshoot; actual response depends on system design |
Flow
| Flow range | 5866RT family range coverage spans 0-3 sccm to 0-30,000 sccm nitrogen equivalent; this configured unit's range must be verified from its label |
| Flow output signal | 0-5 Vdc, 1 kOhm maximum load |
| Flow accuracy | +/-1.0% full scale including linearity at calibration conditions for 3-10,000 sccm nitrogen equivalent; +/-1.5% full scale for flow rates greater than 20 slpm |
Controls
| Pressure setpoint signal | 0-5 Vdc or 0-10 Vdc command, with 5 Vdc reference output available for setpoint generation |
| Valve override | Electrically activated valve override is part of the 5866RT control platform |
Electrical
| Electrical connector | 15-pin D-connector, DA-15P |
| Power requirement, normally closed valve | 3.5 W; +15 Vdc +/-5% at 35 mA and -15 Vdc +/-5% at 180 mA |
| Power requirement, normally open valve | 10.5 W; +/-15 Vdc +/-5% at 350 mA |
Ratings
| Operating temperature range | 32 to 150 degrees F (0 to 65 degrees C) |
Materials
| Standard wetted parts | 316L and 316L VAR stainless steel |
| Seal and valve-seat options | Configured units may use elastomer or metal seals; valve-seat and seal materials vary by configured model code |
Connections
| Mechanical connection options | 5866RT family configurations include stainless steel compression fittings, VCO, and VCR options depending on model code |
Configuration
| Configured-unit rule | Gas, flow range, pressure mode, valve behavior, seal package, fitting, pressure-transducer interface, and calibration details vary by the full configured model code |
| Observed listing context | Stored auction titles identify the unit as BROOKS 5866A1Z1075 MASS FLOW CONTROLLER T252744; T252744 is retained as auction context, not an exact part-number alias |
