61 series digital vacuum sensors are potentiometer-adjustable with a digital display, one PNP output plus analog, and an adjustable hysteresis. A red LED status light is included to announce that the set-point has been achieved and a signal has been sent to the machine controller. Setting is simply a matter of rotating a potentiometer until the desired set-point is shown on the digital display. With G 1/8 NPSF male mounting threads.
