DigiVac m450 Vacuum Regulator for Downstream Vacuum Control with Gas Independent, Isolated, Stainless Steel Sensor and Proportional Valve Control Via Dial Control, Metal

الوصف

The Model 450 is a self-contained, vacuum level control unit for maintaining pressures between 1 and 760 Torr. It provides dependable, digital control of your vacuum system with innovative controller technology to make testing easier. The Model 450 has a gas independent, isolated, stainless steel sensor to enable implementation in the most corrosive environments. The heart of the unit is a proportional valve that allows the controller to make precise changes in vacuum flow to achieve a very stable vacuum level. The unit has a bleed valve that adds bleed control from atmospheric pressure. The Model 450 has full manual control available via a dial on the front panel, or can be controlled remotely via RS232. Using VDS software, the user can run a recipe of 16 time duration and vacuum levels through their PC. The display is an easy to read, back-lit, LCD display with an intuitive readout of the current vacuum level set point, current vacuum level, valve duty cycle, and mode. The Model 450 has been tested in both house vacuum and directly connected vacuum pump configurations to maintain either an absolute or differential vacuum level. This vacuum controller is in use for altitude simulation, pharmaceutical research, and in manufacturing industries to control the vacuum level in evaporator flasks and vacuum vessels. Every unit is calibration under actual vacuum against a NIST traceable standard with data.
