There is an offset on the INA25 that does not correspond to the load cell off-set. In order to make sense of the INA output you must determine this value. The load cell o/p is good when zero corrected. Check out for the commomn mode values on the INA125 I seem to remember an issue with this.

I don't think you will get a simple answer to this one. Mitre(rectangular) bends are frequently equiped with internal turning vanes. The number and size of these will determine the airflow resistance of the bend - which will inturn change the amount of re-generated noise. Most people will just...
Wow a promotional campaign! As I said at the beginning it has gotten rather confused. In Pure terms a transducer converts one form of energy to another, whilst a transmitter does what it says (sends out signals). However if you have a sensor of any type (or brand) it will have to contain both...
As a general rule of thumb they both do the same thing. However some manufacturers call a current output type ie 4-20ma a transmitter and the voltage output types ie 0-5v a transducer. As a guide most users use transmitters with cable runs of 10metres and over.
Just a thought 400 ohm @20mA =8v from a 12v supply are you sure your sensor can work from 4v - the losses in the cable. you may be on the wrong track with the rfi issue.
Hi,
Making sense of fluid contamination monitoring can be a real can of worms. I am aware of two guy's that have been involved in this for several years who would most likely be able to answer your questions, as they do this for a living. I can only give you a phone number and and their names:-...
Assuming you have a ballast resistor for the LED you could simply connect your switch across the LED ie normally closed = shorted out, open switch = flashing LED
I am attempting to predict the change of saturation level of Hydraulic oil, with respect to temperature. I have a device that will give me the percentage saturation level over a thermal range of 10 - 70Cº but cannot as yet translate this into PPM.
