US$108 USB Strain Gauge (Gage) Data Acquisition

When used with a notebook running LabVIEW, the EMANT300 USB 24 bit (DAQ) Data Acquisition module (US$79) together with the Strain Application Adaptor (US$29) become a low cost portable, battery-operated instrument which can be configured as a six channel Strain Indicator and Recorder.

US$128 USB Manometer

Manometers measure pressure which is defined as a force per unit area. The U tube manometer is traditionally used to measure it. By adding the EMANT300 USB 24 bit (DAQ) Data Acquisition module (US$79) and the Pressure Application Adaptor (US$49) to a PC with LabVIEW, you get a low cost USB Manometer.

Process Temperature Control Using PID and LabVIEW

Problem: Maintain the temperature in the 37.2-38.2 C temperature range (37.7-38.3 C, if possible). Overheating the embryo is much more damaging than is under heating it; overheating speeds up embryo development, lowers the percentage of hatchability, and causes abnormal embryos. Long periods of low temperatures will reduce the rate of embryo development. Excessively low temperatures will kill the embryos. Avoid temperatures outside the 36.1-39.4 C. range. If the temperature remains beyond either extreme for several days, hatchability may be severely reduced.

Example demonstrates

  • Measure temperature using Thermistor.
  • Control Lamp output using PWM (Pulse Width Modulation).
  • Temperature control using PID.
