These Baratron® pressure transducers are referenced to vacuum for absolute pressure measurement. Applications include: vacuum furnaces, freeze-drying of fruits and vegetables, gas lasers, automotive component testing, bottle coatings, and vacuum distillation.

These pressure transducers feature all Inconel® construction of the pressure sensor allowing it to operate without damage in virtually any chemical environment, including exposure to halogens, deionized water and steam, and ozone.

These Baratron® capacitance manometers feature a high-level 0-10 VDC analog output signal that is linear with pressure. This analog output can be interfaced with an MKS pressure controller, an MKS power supply/display instrument, or any instrument that meets these requirements.

These Ethernet-enabled Baratron® capacitance manometers can now network with Ethernet hubs and other devices for local or network diagnostics without disassembly or removal from the host system. Like other MKS Ethernet-equipped products, they include an embedded Internet browser software that allows it to communicate with any Windows®-based PC. Since the Ethernet port operates in parallel to the standard analog communications, the device can be diagnosed on a real-time basis during processing which is a huge benefit for users who perform their own system analysis and troubleshooting. Ethernet communications are real-time and can be run in parallel with analog communications, allowing in-situ diagnostics of device and process without cable disconnection.

The embedded Graphical User Interface (GUI) is capable of very detailed analyses of both the Baratron capacitance manometer and the chamber that it is mounted on. Upon initially connecting a Windows PC, the user will see the Device Status screen, which gives a quick “at-a-glance” summary of the Baratron including the pressure, status, and general product information. The user can then move to the Plot screen that shows a real-time plot of the actual pressure that the Baratron sees in the process chamber. This is a particularly powerful function that can be used for detailed process and system diagnostics. Since this mode can display transient pressure changes occurring as fast as 100 milliseconds, it can be used to troubleshoot and diagnose a wide variety of process system issues. Examples include improper isolation valve operation, pressure control instabilities, DC or RF power supply variations, process chemistry issues, and even vacuum pump operation. The Baratron manometer GUI also continuously tracks its own function in areas such as temperature, current draw, and microprocessor operation - and reports back to you via the GUI the problem and when it happened. That helps you to to get the processing system back on-line and generating revenue faster.
