Maximum current source volume (5200 cu.in.):
1 Array of 2 strings with 5 positions (Gun Plates):
- Each string (cu.in.): 520 – (380+380) – 520 – (250+250) - (150+150) = 2600 cu. in.
- Many multiple alternatives with our gun types and volume reducers combinations. Examples:
Maximum potential source volume (9180 cu.in.) :
- 1 Array of 3 strings with 5 positions (Gun Plates). Example:
- Each string (cu.in.):520-(380+380)-(250+250)-(380+380)-520 = 3060 cu. in.
Maximum UTM current source volume (6000 cu.in.) :
- 1 Array of 3 strings with 5 positions (Gun Plates):
- Each string (cu.in.): 520-380-(250+250)-(150+150)-(150+150)= 2000 cu. in.
