3 Important Information for IPM650
3.1 Performance
The IPM650 is a microcontroller based digital panel meter that monitors the activity of a vast range of
sensors. This includes Wheatstone bridge strain gauge and amplified output Torque/ Force/ Pressure/
Displacement sensors. All of the measurements are based on a high accuracy, low noise, 24 bit resolution,
Analog to Digital Converter with a non-linearity of 0.001%, and a temperature coefficient factor of less
than 5 PPM (zero and span drift). All analog components, not only the ones that provide the
requirements for ADC, such as reference voltage, but also the ones which are employed for analog
output, excitation voltage, and input/output buffers are low noise, low distortion, low temperature
coefficient, and high precision/accuracy parts. The combination of these components, along with a high
speed micro-controller integrated with a precision DAC controller has provided a high accuracy
instrument, which is able to measure the activity of a 2 mV/V sensor with up to a 500,000 count (total)
noise free base! The high precision DAC controller has been exploited to provide a ±5 V output with 100
μV resolution and/or (0-25mA) current output with a 0.5 μA resolution. A wide range of bridge
resistances and input/output impedances of external instruments can be applied to this device without
any lack of performance.
The IPM650 accepts amplified voltage input (±12 VDC), current input (up to 30 mA), and bridge input
(up to 500 mV/V), and has the capability to provide power to FUTEK rotary torque sensors (24 VDC/ 1 W
and 5 VDC/ 0.05 W).
