    (or dry) condition and decreases as the rate of flow increases (or as a liquid quenches the sensor/wet condition). The DELTA M Corporation sensor excitation method relies on constant current to the heated and reference sensors. Thus power to the heated sensor is not constant but changes linearly with temperature as the sensor resistance changes.

  • Page 8: Level Switching

    DELTA M Corporation 3242-OM-04 3/27/02 Level Switching The thermal differential created between the heated and reference unheated RTD pair is a function of the liquid or gas medium with which the sensor is in contact. The point level measurement application uses the heat transfer differences between two media to detect liquid level.

  • Page 9: Flow Switching

    The DELTA M thermal-differential technique is one of two methods that directly measure the mass flow. For ease of comparison most flow applications are presented in terms of velocity which is independent of the flow cross sectional area (i.e.
  • Page 10 DELTA M Corporation 3242-OM-04 3/27/02 Figure 3.A shows a block diagram of the microtuf® switch. Once the switch is set to respond to the minimum and maximum flow rates (or wet vs. dry conditions), the trip point is set by adjusting the Trip Adjust Potentiometer. Solid state electronics transform the flow (or wetting) induced temperature differential into a voltage that is compared to a control voltage.
