Sierra Instruments SmartTrak 140 ultra-low ΔP mass flow controller
The Sierra Instruments SmartTrak 140 is an ultra-low ΔP mass flow controller for high-performance mass flow control applications where minimal pressure drop is a key consideration.
The SmartTrak 140 controls gas mass flow up to 500 slpm (nlpm) with an ultra-low ΔP of 4.5 psid.
The mass flow controller offers an accuracy of ±1.0% of full scale, repeatability of ±0.2% of full scale, flow range up to 500 slpm (nlpm), 316 stainless steel construction, and control valve with large flow coefficient (Cv) for precise control at low ΔP.
The 140 is a hybrid of two Sierra technologies: the SmartTrak 100, with its laminar flow element, sensor and digital electronics, combined with the SideTrak 840 low ΔP valve which offers the very large flow coefficient.
The 140 also offers the company’s Dial-A-Gas Technology allowing users to set zero, span and full scale for 10 different gases independently in the field. In addition, a handheld or instrument-mounted user display/interface called the Pilot Module is said to make field adjustments and reconfiguration easy.
