With the Active Sensor Controllers, you have all measurement values at a glance. Two compact control units are available for simultaneous operation with two or four vacuum sensors. Used either as a tabletop or a rack mount, they feature large LCD displays with background illumination, several relay contacts, as well as both USB and RS232 interfaces. The CTR 002 and CTR 004 allow full control and configurations of the sensors thanks to intuitive navigation. Parameters such as gas type correction factor, pressure units, setpoints and other beneficial functions are easily adjustable.
