Clausings factor 8 Exhaust Time (Low/Medium Vacuum) K The time (t) required to exhaust a chamber at low vacuum with volume V (L), from pressure P1 to P2, using a pump with pumping speed S (L/sec) is t=2.3(V/S)log(P1/P2). In high vacuum, this is subject to the ultimate pressure limit imposed by outgassing and leakage as characterized above.

Caution Pilot port piping 12(P1) and 10(P2) piping should be as follows according to the model. 2. Do not warm the coil assembly with a heat insulator, etc. Use tape, heaters, etc., for freeze prevention on the piping and body only. They can cause the coil to burn out.

Pilot port P1 and P2 piping Please arrange P1 and P2 piping as follows according to the model.
Note 3) Hysteresis mode: When the values of P1 and P2 are the same or when |P1| > |P2| within 3 digits, the hysteresis will be automatically 3 digits for the set value of P1. Window comparator mode: The hysteresis is 3 digits, so separate P1 from P2 by 7 digits or more and set them. 1 digit is the minimum pressure display unit. (See the table above.)
