Pressure transmitter , connection?
hi,
We have installed a DX AHU, with external condensers.
On the condensers we ve got a Pressure Transmitter which needs to be installed on the suction line (according to manuals) to read refrigerant line pressure and operates Fans accordingly.
From what I know, pressure transmitter converts pressure into linear electrical output signal.
So in a few words, depending on the pressure of the refrigerant pipe line the condenser fans starts and stops accordingly.
True?
thanks,
Z

Re: Pressure transmitter , connection?
if your transducer is controlling the condenser fans then it should be fitted on the (thinner) liq line sometimes on the discharge line too,check the installation manual or if in doubt fit a schraeder stubb on both lines incase u have problems when comissioning

It's impossible to make anything foolproof because fools are so ingenious...
Don't ever underestimate the power of stupid people when they are in large groups.
Please, don't teach me how to be stupid....
No job is as important as to jeopardize the safety of you or those that you work with.

thanks guys. it is fitted on the high pressure pipe line and controlling the fans just fine.
