I am collecting the pieces required to measure gas pressure in the ducts of an engine running at 8,000 RPM.
I am hoping that a Picoscope of some kind can complete the hardware collection of my system.
I would like to measure at each degree of crankshaft rotation if possible.
(8,000(RPM)/60 seconds per minute) * 360 (degrees per revolution)
= 48000 samples per second.
I need to trigger the start of a cycle each camshaft revolution. I hope that I can use a pick-up or an encoder for that.
I have 3 sensors to collect data from (they each have amplifiers).
I would be interested to have more sensors if possible, 4 would be good, but 8 would be great unless it multiplied the cost (this is a personal hobby project).
I will want to display the collected data in a graph.
If there is an application that does what I want easily, I might use it.
I expect that I will prefer to collect the data from a text file and graph it with an application that I will write.
I wonder if there is a way to graph the data in real time (maybe in coarser frequency).
Can you tell me if there is a PicoScope that can do this, if so what model?
I am looking at the 3000 series scopes but do not have a good enough understanding of the technical specs to know if it is capable of supporting this project.
The way to figure out what you ask is to compare the output specifications of the sensor or amplifier (i.e. the one that will be connected directly to the PicoScope), against the input requirements and specifications of the PicoScope to see if they are compatible. So, here are the results of the relevant comaprisons:
The KISTLER PR-Amplifier Type 4622A AMPLIFIER has a maximum full-scale output of 10V, which has a corresponding input range on the PicoScope 4824. The maximum frequency response is 40kHz, which is well within the 20MHz maximum Bandwidth of a Picoscope 4824 input channel.
The KISTLER 4618A0 DYNAMIC PIEZORESISTIVE AMPLIFIER has a maximum full-scale output of 1V on it's minimum output range, and a maximum full-scale output of 10V on it's maximum output range, both of which have corresponding input ranges on the PicoScope 4824, and its frequency response is the same as the 4662A.
Unfortunately, I couldn't find a data sheet for the OPTRAND C52394 IN CYLINDER COMBUSTION PRESSURE SENSOR. However as long as the combustion pressure doesn't have a rise time that is quicker than 17.5nS (or a bandwidth greater than 20MHz) you will be able to measure it with a PicoScope 4824. If it has a large enough output voltage (20mV or greater) you will be able to connect it directly to the PicoScope (otherwise it will need amplification).
You will need to provide the excitation voltage required to drive the amplifiers & sensors.
