JTSED Electronic Vacuum Switch with Digital Readout

JTSED Electronic Vacuum Switch with Digital Readout

The JTSED Electronic Vacuum Switch converts the vacuum level into digital output for connection to PLC systems as well as into analog output for the on/off control. The JTSED Electronic Vacuum Switch is identical to the JTSE Switch except for the addition of a digital LED display. Vacuum levels can be manually adjusted in psi, bar, or in Hg over the full range of vacuum.
