  • Pressure transducer with millivolt output
    Pressure sensors with millivolt output signal, in the Danfoss language known as "pressure. transducers", were in past days used in general industries due to limited technological capabilities. Nowadays such sensors are to a great extent replaced by ratiometric pressure transmitters with. amplified
  • Determination of Ionized Calcium in Skim Milk
    Ionized calcium in skim milk can be measured directly in the normal range (1 mM to 4 mM) utilizing the Iotron Calcium Electrode. Potassium Chloride is added to both standard and sample for consistent ionic strength. Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV
  • Chloride Determination in Copper-Sulfuric Acid Plating Bath
    Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV preferred. Specific ion meter will provide direct readout of final answer or concentration factor. Consult manual for millivolt measurement instructions. If the electrode is being used for the first time, please follow
  • Chloride Analysis in Water
    and swamp waters. Sulfide is easily removed by aeration. Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV preferred. Specific ion meter will provide direct readout of final answer or concentration factor. Consult manual for millivolt measurement instructions.
  • Bromide Analysis in Nickel Sulfamate Bath
    may be present in trace amounts. As bromide concentrations may vary widely, use the following method as a general guide line. Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV preferred. Specific ion meter will provide direct readout of final answer or concentration factor
  • Bromide Analysis in Water
    The following analysis is valid for bromide levels as low as 0.5 ppm. Check the deionized water used in reagent preparation. The specific conductivity should be no greater than 2.0 uSCM-1 (5 Mohms). Sample solutions should be free of iodide and sulfide ions. Equipment: Meter: pH/Millivolt meter
  • Application Note: Transducer Tester
    Manufacturers of solid-state pressure transducers face a demanding task when testing this kind of electro-mechanical product. The test typically must measure the transducer output in millivolts at a ?xed excitation voltage and at a known. pressure input. The test must also make certain
  • Proper Calibration Techniques (.pdf)
    Before any electrodes are placed into initial service and then about once a month thereafter, depending on the application, a two point calibration of the electrodes are required. A two point calibration corrects for changes in the output of the pH electrode (slope) and the millivolt offset (Eo
