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.
