The Type 270 is a half-rack module that provides power and signal conditioning (oscillator, demodulator, and amplifier) for any of the 600 Series High Accuracy Baratron sensors. The 270-0 has no display for systems where the output can be read elsewhere, such as on a computer data acquisition system or DVM, while the models 270-4 and 270-5 provide front panel digital display of pressure.
The Type 274 provides operation of one, two, or three high accuracy sensors with a single Type 670 Electronics Unit. The 274 provides heater power for temperature-controlled sensors (Types 690, 698, 590). All sensors are kept warmed up and ready for reading by the 670. The 670 can sequentially read any one of the sensors, as selected by a switch on the 670's front panel, or by a remote ground closure.
With the Type 250B/E Gas Inlet Pressure/Flow Control Module. Type 250 B/E process control can be manually adjusted through a front panel potentiometer or remotely programmed with a 0 to 5 VDC analog signal for profile generating. With the multi-set point option a simple ground closure will select one of four preset set points. The basic Type 250 provides a simple analog error meter to show deviation of actual versus desired set point. It is also available with an optional 4 digit LED display which provides a readout of the input transducer signal and eliminates the need for a separate display instrument.
The type 647 controls six mass flow controllers with cards available per your request. The 647A, 647B and 647C replace the 147A, 147B and 147C. View the 647C literature.
