Brooks Instrument manufacturers solutions for flow, pressure, and level measurement solutions

Overview

The Brooks 0254 is a four-channel power supply, readout, and set point controller. This innovative, reliable microcomputer-based controller provides power for up to four Brooks thermal mass flow, Quantim Coriolis mass flow, and/or pressure devices; all in a new compact design. Additionally, the 0254 can be used to generate flow setpoint commands, display flow rate, totalize flow, for blending multiple flow streams, and more. This fully RoHS compliant device has a very user-friendly operation and is offered with multiple mounting capabilities such as rack mount, panel mount, and table-top mount.

Products

Gas and Liquid Mass Flow Secondary Electronics, 4 channels

Four Channel Display
The process variable and setpoint for each of the four channels are displayed simultaneously for quick reading and adjustment. The value displayed on each channel can be independently set for percent full scale or engineering units to display flow rate, pressure, density, or temperature.

Backlit Graphic Display The 0254 features a large, high contrast, backlit graphic display which allows the user to view real-time process variables and the programmed setpoint for each connected device right on the home screen. This enables the user to rapidly identify and make in-process adjustments in seconds. The display and audio indicators provide the user immediate status quantities, rates, and diagnostic operating status.

Communication
Every 0254 comes with a RS-232 port, giving users serial communication capability. The RS-232 port provides remote readout, setpoint, control, and data acquisition. Diagnostics Powerful automatic built-in diagnostic tests support easy installation and assist in ensuring a long, trouble-free operating life. These tests include overall system operating status, memory conditions, communication adapter status, display functionality, and keypad operation.

Sensor Factor
A gas sensor factor dropdown list is a standard menu feature, allowing the user to adapt the 0254 to any non-calibrated fluid.

Approvals and Certifications
The 0254 is fully RoHS compliant to EU 2002/95, CE certified to EN61326-1, FCC certified to Part 15 Class A and Part 68. UL general purpose approval to UL61010 is pending.
