Hi
I have a sitrans probe a 12m ultrasonic transmitter for measuring levels and volumes of tanks,
I powered it up, but it stucks at the initialization screen.

Any idea how to solve this issue please?

Hi Sayah,

The Sitrans Probe is -as you know- a 2-wire instrument (and it's an excellent one!).
It needs some current to start up. Maybe your analog card does not provide enough power, or your loop resistance is too high. I have seen this many times.
By means of test, connect your Sitrans Probe directly to a 24V power supply (e.g. Sitop Power), and see if it does start up completely. When the start up phase is done, you will hear / feel the pulses on the sensor face.

Good Luck,

SonicRanger.

Hi again,

I tried with independent PS and it works laugh.
However, I still need to connect it to my data acquesition system to enable reading in my system.
which is not possible as it's only 2wire sensor


I used a 250 Ohm resistor in series with the sensor and it WORKS.

Many thanks for your help blink

Cheers,
Sayah
