The PT-VI Basic Platform comes with two built-in vacuum sensors. As an option, one or two external cleanable vacuum sensors can also be connected. Analyze this on the external analog input (s) and up to four vacuum signals simultaneously. The external cleanable stainless steel vacuum sensor resists the various influences found in parlors, making it ideal for measurements during milking. These sensors can be cleaned under running tap after use. The sensors have an M12 connector and can be connected to the external analog input of the PT-VI with the M12 / M12 cables.
