I have a circuit which has a 48V supply and a water conductivity cell
having a resistance. The current in the circuit is of the range 0-2
mA. I want to measure the current in this circuit accurately. The
easiest solution is to measure the current across a resistor by adding
a shunt in series with the 48V battery. But the resistor may change a
little bit with time and temperature. Can somebody recommend a
solution for measuring current at this high voltage of 48 V. I have
gone through some off the shelf IC's but they are not for this voltage
range. I need a reliable solution for the same. Can somebody help.
