Sensor and transmitters spike problems

Published on by in Technology

Hi all,

May I know what is the main reason sensors and meters create spikes throughout its service on water monitoring? How can we prevent it from happening and act before the instruments spike/ dive?

Please do share your experience here. Thank you very much

  1. We are located in Brazil, and install instrumentation since 1997. I can see the spikes in some data when reading papers or looking databases, and I believe that skypes can have several origins.  To long time monitorings, can happen that when the user take out the sensor the system take a reading. In others situations can be a mistake from the logger system about power up the sensor (low power in the batteries), low water temperature where the sensor take more time to send back the values.  Several others are the possible reasons.  Could be important know a little more about the system like: battery and logger submersed in coll water or in surface, long cables, battery type, etc.

  2. Hi Johnny,

    Wow that's something I don't know about because we are so used to the all year hot weather here in Asia.

    But in Singapore we only have very hot and occasional rain weather, will high temperatures affect the spiking frequencies as well?

    1. In Texas we receive very hot temperatures as well, it will spike the analyzers but we try to keep them in a climate controlled environment using a/c and heating units. We monitor the temperatures in our facilities.  We are in the process of relocating  all transducers and sensors into the facilities and removing them from direct contact with the environment.  So far it has worked exceptionally well.

  3. Cold weather is the biggest culprit we face for drops and spikes on our sensors. Especially single digit temperatures.  We try to counter this challenge with heat wraps and strategic placement of the outside sensors.

     

    The second reason is during reagent change outs for the various analyzer equipment. There tends to be a delay for the meters to register proper readings until the analyzer synchronizes.
