Rave Scientific offers the Pfeiffer The ActiveLine Wide Range gauges-the total pressure vacuum gauge with analog signal outlet The ActiveLine series offers a wide range of vacuum gauges that work on a variety of measuring principles and have a classic analog outlet. The series thus covers the technically relevant vacuum range from ultra-high vacuum to overpressure. The outlet voltage of the transmitter, which is proportional to the pressure, can be displayed as pressure on the three controllers or read into controllers through analog inputs for further processing.
