Brooks Instrument 5866 Pressure Controller and Flowmeter

About this part

5866RB1A1B4Q2YC is a configured Brooks Instrument 5866-family pressure controller and mass flow meter. Brooks documents the related 5866RT platform as using a remote pressure-transducer signal and an integral control valve to maintain upstream or downstream pressure while measuring gas mass flow. The exact suffix is configuration-specific; gas, flow range, pressure mode, valve action, seals, fittings and remote-transducer interface require verification from the unit label and system records

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

Specifications

Identification

Series family

Brooks 5866 pressure controller / flowmeter platform

Function

Pressure control	Controls upstream or downstream pressure using a remote pressure-transducer input and integral valve
Flow measurement	Measures mass flow through the control valve and supplies a proportional 0-5 V signal

Pressure

Remote transducer signals	0-5 V or 0-10 V pressure-transducer output
Control range	100:1 with a 0-10 V remote pressure transducer
Maximum working pressure	1500 psig for the documented 5866RT family

Performance

Pressure response	Less than 0.8 second typical for a 0-100% command step; system design affects response
Flow accuracy	+/-1% of full scale through 10 slpm; +/-1.5% of full scale above 20 slpm
Flow repeatability	+/-0.25% of rate

Flow

Family range coverage

3 to 30,000 sccm nitrogen equivalent

Environment

Operating temperature

0 to 65 C

Electrical

Connector

15-pin DA-15P D-sub

Materials

Standard wetted material

316L and 316L VAR stainless steel; seals and valve-seat materials vary by configuration

Configured-unit checks

A complete 5866 configuration must be matched to the pressure-control system.

Confirm whether the unit controls upstream or downstream pressure.
Match the remote pressure transducer's range and signal.
Verify calibrated gas and full-scale flow.
Check valve action, seals, fittings, power and connector wiring.
