Hi
I have received a transmitter with 3 adjustment screws.

Z stands for zero
S stands for span
D stands for what?

Unfortunately i cant read the model number. But the manufacture is ABB

Thanks for your help

 

Your guess is as good as mine:
Density ?
Damping ?
Differential ?
Druck (pressure) ?

Well my boss told me that it is for dead band. I didn't agree with him.

 

What is the instrument? What's it do?

 

Hello,

There seems to be a nameplate a bit to the right.
Can you post a picture of that nameplate?
There might be a clue on it.

Might be a pressure switch...

 

Its a pressure transmitter from ABB co.
Its too old.
I yhink i found the answer.
D stands for dampening.
Now I dont have any access to take another picture
