Brooks Instrument SLAMf Series IP66 Thermal Mass Flow Controller

Name: Brooks SLAMf IP66 Mass Flow Controller – Datasheet & Quote
Brand: Brooks Instrument
SKU: SLAMf

Description

Gas mass flow control in a dust-tight, washdown-rated housing

The SLAMf Series takes the sensor and valve technology of the Brooks SLA family and places the electronics in an IP66 enclosure that is also available with hazardous-area approvals. It is aimed at plants where a standard flow controller would face dust, moisture, hose-down cleaning, temperature extremes or explosive atmospheres. The controllers are the SLAMf50, SLAMf51 and SLAMf53 and the meters are the SLAMf60, SLAMf61, SLAMf63 and SLAMf64.

Brooks describes a modular platform intended for drop-in replacement and upgrade of many other brands of mass flow controller, with a broad choice of analog and digital interfaces. Typical fields named in the datasheet are chemical and petrochemical research, laboratory, analytical, fuel cell, biotechnology and life science applications.

Selecting body size, connection and certification

The SLAMf ordering code follows the SLA structure with the base model letters SLA, package MF, a function digit (5 controller, 6 meter) and a body-size digit: 0 for 3 ccm to 50 lpm, 1 for 15 to 150 lpm, 3 for 100 to 2500 lpm and 4 for 1000 to 20833 lpm nitrogen equivalent. Digital communication choices include DeviceNet and Profibus variants with M20 conduit or PG11 cable gland, RS485, EtherNet/IP and PROFINET.

Position XIII sets the area certification: safe area, Zone 2 ATEX, Div 2 / Zone 2 UL Listed, UL Recognized, Zone 2 IECEx or KOSHA. The Biotech Performance and Premium packages, with optional CO2 actual-gas calibration on the two smaller bodies, are selected in position XII.

What to confirm before ordering

Tell us the gas, flow range, line pressures, fitting, valve action, supply voltage, interface and the exact area classification of the installation. The datasheet limits hazardous-area versions to 0 to 65 C, and warns that more than 40 psig inlet is required above 100 lpm of nitrogen equivalent. A nameplate code from an existing unit makes a like-for-like check faster.

How the Brooks SLAMf works

A thermal sensor measures the mass flow of the gas in a small bypass. The electronics compare the reading with the setpoint. A control valve then opens or closes to hold the flow at the setpoint. The electronics sit in a sealed housing.

Installation, commissioning and maintenance notes for the SLAMf

Fit the device on a clean gas line in the stated direction. Wire the supply and the signal through the conduit entry. Leak-check the fittings. Check the zero with no flow. Keep the gas dry and free of particles.

About brand

Brooks Instrument makes mass flow controllers, flowmeters and pressure and vacuum instruments for gases and liquids. The industrial chemist Stephen A. Brooks started the business in 1946 as the Brooks Rotameter Company near Philadelphia, building variable area flowmeters. After many years as part of Emerson, Brooks was sold to American Industrial Partners at the end of 2007 and has been a division of Illinois Tool Works (ITW) since January 2012. It is headquartered in Hatfield, Pennsylvania.

Seven Star LLC is an independent supplier listing Brooks Instrument thermal and Coriolis mass flow controllers and variable area flowmeters for buyers in Oman and the GCC. Instruments are matched from the model code and the gas, range and calibration data on the label.

Where Brooks instruments are used

Brooks mass flow controllers dose gases in analyser systems, catalyst and pilot plant testing, gas blending, burner and combustion control, fuel cell test stands and semiconductor tools. Variable area flowmeters are widely used on purge gas, seal flush, sample and chemical injection lines in oil and gas, refining and petrochemical plants, where a simple local indication without external power is preferred.

Ordering Brooks instruments: what we need

Send the full model code and serial number from the label. Mass flow controllers are calibrated for a specific gas and full-scale flow, so state the gas or gas mixture, flow range, inlet and outlet pressure, temperature, process connection, seal material, signal (analog, RS-485, DeviceNet, EtherNet/IP or other) and any hazardous-area requirement. For variable area meters add the fluid, density, viscosity, flow range, connection size, materials and whether alarms or a 4-20 mA output are needed.
