@Bhaskar I have this unit on a Feather ESP32 with headers wired to the I2C channels. On the Feather ESP32 the SDA/SCL are different than other boards.
When using feather’s I2C pins, use this code in ADS1115.cpp:
#define SDA_PIN 23 //default is 21
#define SCL_PIN 22 //default is 22
The problem I am having is that my Pressure Transducer works on my PLC’s, ( I have tested with 2 separate ones) But it doesn’t work with this board. I have read of others having to remove things off the board?
–Type 4 Current Loop with PR33-7
I spent over 70 per board, and I don’t like the idea of having to modify them, lose the warranty just to get them to work.
Any ideas of what I can do, either way?
Please can you share the datasheet or the part number of the pressure sensor you are planning to use with this board?
is it a 2 wire sensor?
Thanks for responding.
It is SKU: PR33-8
It is a 2 wire sensor, external power 8-32v. I am powering with a 12v power supply.
If its a 2 wire sensor then you can power it using the PR33-8.
If you are powering using external power supply then it might be a 3 or 4 wire sensor.
for that you will need a different board.
So the part I bought is intended to provide power to the sensor? Our sensor can be powered by a rand 8-32vdc. So the 16v provided should work and I need to disconnect my power supply to the sensor.
Your other board allows the sensor to be powered externally?
In general there are two kinds of 4-20mA sensors. one which can be powered and read 4-20mA signal using same wire. other one are which have separate connections for power and 4-20mA signal.
without the sensor datasheet i cant say how it works but you can give it a try.
Yes, the PR33-15 works with the sensors which are powered externally.
I appreciate the clarification of the 2 products. In the end I didn’t read the description well enough to see you had a product for each type.
