Product description
Parameters

Features

1. High Accuracy and Fast Response

The accuracy of the CS200 MFC has been improved to ±1.0% of S.P., and the most advanced models have a reduced response time of less than 0.8 sec.

2. Low Zero Drift and Temperature Coefficient

The invention of new sensor technology enables the CS200 MFC to maintain stability and withstand temperature fluctuations. Without an auto-zero amplifier, the expected zero drift is less than 0.6%F.S./year, and the temperature coefficient is less than 0.02%F.S./℃(zero)，0.05%F.S./ ℃ (span).

3. Metal-Sealed Models and High Purity Feature

The wetted flow path of-the-the-line CS200 MFC is constructed from surface-passivated stainless steel. All CS200 MFCs are assembled in Sevenstar’s ultraclean Class 100-class cleanrooms in accordance with both SEMI and ISO 9001 standards.

4. Compatible Interfaces

The CS200 MFC is compatible with the following interfaces, which may be selected by the customer:±8V-±16V double-end power supply and +14V-+28V single–end power supply; digital or analog signal input and output; SEMI standard mechanical dimensions; and RS-485 or DeviceNet communications module.

5. Miscellaneous Functions

Powerful customer software comes standard with each model, while additional functions such as multi-gas，multi-range，auto-zero, alarms, soft start, and delay are available as customer selections.
