MKS i-BARATRON Type DMA Capacitance Manometer with DeviceNet Digital Interface
The MKS Baratron Type DMA Absolute Pressure Transducer with a DeviceNet™ Digital Interface is part of the MKS family of general purpose pressure transducers designed to provide accurate, reliable, and repeatable pressure measurements in the range from 1K Torr to as low as 20 mTorr Full Scale (FS). The DMA is designed specifically to meet the needs of vacuum process systems where environmental and process conditions are particularly demanding. Temperature control of the DMA (45° C) and DMA (80° C) transducers minimizes the effects of ambient or process temperature variations typically encountered in process line environments. The DMA (45° C) controls its temperature at 45° C nominal. The DMA (80° C) transducer is internally controlled at 80° C, thereby minimizing contamination from the process. The DMA (Ambient) is unheated. The DMA unit exposes only Inconel® to the process permitting use with corrosive or dirty gases and eliminating contamination of the process with transducer materials.
Measurements are independent of gas composition. Using the latest single-sided, dual-electrode Inconel transducer design, coupled with a low impedance, fixed-frequency bridge signal conditioner, this instrument is capable of withstanding high overpressure conditions (45 psia) with minimal or no shifts in output over their range. The advanced bridge signal conditioning technology provides high accuracy and operation which is extremely temperature-stable at operating pressure. The transducer provides a digital pressure signal through the DeviceNet communications interface, or as an analog signal through a 9-pin Type DE-9S Interface connector for direct measurement. Output is linear and proportional to pressure. The operational settings of the DMA unit are controlled using DeviceNet communications, which support 125, 250, and 500 Kb data rates. A non-volatile storage device stores the user settings.
