Hi All

I have a faulty oil differential transducer on a Sabroe compresser. HPC series. What i would like to know is, the transducer under pressure, ie, will i lose some of the charge if i dont pump the system down when i remove it. I ask the question because a sub-contracting engineer told me a temperature probe, PT100, on the same system was under pressure. However when i removed it due to a fault i found it wasnt under pressure.

Thanks
