(or as a liquid quenches the sensor/wet condition). The SIERRA INSTRUMENTS 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 6 FIGURE 1A LS3200/FS4200 Innova-Switch™ OUTLINE DIAGRAM STANDARD 2.0 INCH INSERTION (KILLARK ENCLOSURE – NEMA 4-EExd 11B, T4) IM-215 Rev-A.1 Series Innova-Switch™ Page 6 of 42...

Page 8: Level Switching
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 SIERRA INSTRUMENTS 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 When the sensor is inserted into a liquid or gas the heated RTD is strongly affected by the velocity of the medium. Flow past the heated RTD changes the heat transferred from the surface of the sensor. This cooling effect reduces the ™...

- Page 12 Figure 3.A shows a block diagram of the Innova-Switch™ 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.

For applications where the electronics must be located away from the sensors due to elevated process temperature, accessibility, etc., another instrument head containing the electronics is remotely located (See option RE-Remote Electronics section 3.2.2).
