Hi all,
I am after a suction transducer for a Mcquay air cooled screw that is running on the old micro tech controller.

Chiller model: ALS 181.2 ST
Compressor: Frame 2 screw (liquid cooled motor)
refrigerant: R407c

The only markings i can make out are, it has a blue dot to symbolize the low press. ( red dot for discharge transducer)

I have tried carel transducers -05-7bar(4-20ma) and carel 0-10 bar 4-20ma.

Any help would be appriciated even if it is only the opertating characteristics of the transducer.

Thanks Adrian

Perfect :D
Thanks Ptsac, That's the one. I'll use this mob a bit i think. Mcquay Australia have dropped the ball when it comes to getting parts etc. Since Daiken took over it has been impossible, especially for the Micro tech stuff. I don't think daikan care about the mcquay product which is a pitty as "some" mcquay stuff IMHO is great. I am a big fan of the fr4 and 3200 screw compressors.

Cheers Adrian
