Standard units are rated from vacuum to 7Bar. If operation at high pressures is needed (for example, sub-sea equipment submerged in mineral oil) then the use of Extended Range Product Option ‘V’ is recommended which has a maximum recommended operating pressure of 4,000psi or 280Bar. Higher operating pressures may be possible subject to qualification by the user in host equipment. ‘V’ designated products undergo a hard epoxy encapsulation process which ensures absence of internal voids. Specify ‘V’ at the end of the standard Product Number.
