( Brand: Sierra ), ( Manufacturer Part Number: 840-M-1-V1 ), ( Part Type: Flow Controller Meter )
The Sierra Instruments 840-M-1-V1 flow controller is a precision instrument designed for controlling the flow of air. This particular model has a maximum flow rate of 30 standard cubic centimeters per minute (sccm), making it suitable for applications that require moderate flow rates.
The 840-M-1-V1 is a mass flow controller, which means it measures the mass flow rate of a gas by continuously monitoring the pressure drop across a restrictor and the flow rate-dependent thermal conductivity of the gas. This method ensures highly accurate and stable flow control, even in applications with changing gas properties.
The controller is equipped with a digital display that shows the actual flow rate, set point, and percentage of error. It also has built-in diagnostics to help identify and troubleshoot any issues. The controller is compatible with a wide range of communication protocols, including RS232, RS485, and Ethernet, allowing easy integration with various data acquisition systems.
The 840-M-1-V1 is designed for ruggedness and reliability. It has a compact and lightweight construction, making it easy to install and transport. The controller is also equipped with a built-in temperature sensor and heater, ensuring stable operation in a wide temperature range.
In summary, the Sierra Instruments 840-M-1-V1 flow controller is a high-performance, compact, and rugged instrument for accurate and stable air flow control. Its mass flow measurement method, digital display, and wide range of communication protocols make it a versatile tool for various applications.
