Model 201

The Model 201 series gauge controller is a highly configurable, digital vacuum control instrument, capable of driving and combining multiple sensors. This device can save space, money and complexity, by combining many tasks into one device, while enabling the user to have any level of accuracy desired for different ranges. It is a highly flexible, multigauge controller, that accepts different inputs based on driver board and sensor election. It can have different outputs including: Analog Recorder, RS232, Ethernet, SPDT relays and VLC. The 201 is configured with sensors based on the accuracy and range required for a specific application, and displays the pressure reading in user selectable units of: Torr, mbar or kilopascal. The Model 201 can either be panel mounted or sit on a bench top, and can use thermocouple, capacitance manometer, PCG750, CDG500, or PVG500 active gauges. The 201 has a built in feature that displays "range" when the sensor is below its useful range, to minimize confusion when looking at multiple instruments. It displays "error" if there is a sensor input fault, and puts any configured relays immediately to the safe atmospheric setting. The 201 also has a rich command set, to empower the user to control the set points and PID variables, via a local RS232 session or from a web browser a world away.

When purchased with the optional VLC control, the Model 201 regulates the vacuum level at a particular set point, between 30 millitorr and 5000 millitorr. This vacuum regulator works on the principal of regulating the bleed of a vacuum vessel to atmosphere, much like the way many freeze dryers do. The VLC option also has PID variables, to enable the user to adjust the nature of the control. The 201 is intuitive, and requires very little setup, which makes it easy to control a process or perform precision experimentation.

An instrument equipped with Ethernet gives the user the power of the ReAct browser, to remotely monitor and control all aspects of the 201. The 201 greatly facilitates process control and easy data sharing, to simplify production and laboratory work.
