As you pull on it, the resistance increases (the particles get further apart). As you stretch it out, the resistance increases. So let's say you have a 6\" piece - that's about 2.1 Kohms. Stretch it to 10\" long and now it is 10\"\/6\"*2.1K = 3.5 Kohms. You can stretch the rubber about 50-70% longer than the resting length, so a 6\" piece shouldn't be stretched more than 10\". Once the force is released, the rubber will shrink back, although it's not very 'fast' and it takes a minute or two to revert to its original length.

This results in a change in resistance that corresponds to the distance from the top of the sensor to the surface of the fluid.

That means that unless you want to get a battery involved, you have to stick the measurement resistor between the target ground and true ground. This can cause problems with circuits since electronics tend to not like it when the ground references change and move with varying current draw. This chip is much smarter - it can handle high side current measuring, up to +26VDC, even though it is powered with 3 or 5V. It will also report back that high side voltage, which is great for tracking battery life or solar panels.\u003cbr\u003e\u003cbr\u003eA precision amplifier measures the voltage across the 0.1 ohm, 1% sense resistor. Since the amplifier maximum input difference is ±320mV this means it can measure up to ±3.2 Amps. With the internal 12 bit ADC, the resolution at ±3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is ±400mA and the resolution is 0.1mA. Advanced hackers can remove the 0.1 ohm current sense resistor and replace it with their own to change the range (say a 0.01 ohm to measure up 32 Amps with a resolution of 8mA)\u003cbr\u003e\u003cbr\u003eWe include a 6-pin header (so you can easily attach this sensor to a breadboard) as well as a 3.5mm terminal plug so you can easily attach and detach your load.\u003c\/p\u003e\u003cp\u003eUsage is simple.

We have also increased the stop range and reduced standby power consumption, so the current draw is less than 1mA without signal control.

The NanoMuscle Rotary actuators come in two different versions: the 2-pin NM70R-2P, and the 6-pin NM70R-6P. The -2P actuator ‘bounces’ between limit stops when connected to a power source, and the -6P provides greater control, with access to end limit sensors, and can be driven by the MADv5 (sold separately). Operating voltages are ~3-9V.
