3. Vibex Technology Vibrating Fork Technology: Natural resonant frequency is the same as a tuning fork. Frequency depends on dimensions, shape and material The natural resonant frequency of Vibex™ is 1,200 Hz Frequency avoids interfaces with plant vibration, and optimizes size of fork Measurement Principle

4. Vibex Technology  If the vibrating fork is covered by liquid, its natural resonant frequency changes, which is detected by the sensor and converted into a switching output signal. If the vibrating fork is not covered by liquid any more, its natural resonant frequency changes back and so does the state of the switching output. Measurement Principle Frequency Amplitude Fork uncovered Fork covered Fork corrosion Error F F U U

5. Simple, compact design Extremely reliable Setup without adjustment or calibration Independent of liquid properties and installation conditions No moving parts, thus wear and maintenance free Vibex Unique Features

6. Floats: No moving parts inside the tank, i.e. no maintenance required Independent of the density of the liquid, i.e. one sensor for all types of liquids No problems with turbulence, aerated liquids/air bubbles, foaming, coating liquids/build-up, slurries, solid particle content Conductivity: Independent of the conductivity of the liquid, i.e. one sensor for all types of liquids...works well in oil Capacitance: Independent of the dielectric constant of the liquid, i.e. one sensor for all types of liquids and no (re-)calibration necessary... works well in oil Vibex Advantages

8. Tracer Technology  TDR (Time Domain Reflectometry) Technology: low-energy, high-frequency electromagnetic impulses, generated by the sensor’s circuitry, are propagated along the probe which is immerged in the liquid to be measured.  When these impulses hit the surface of the liquid, part of the impulse energy is reflected back up the probe to the circuitry which then calculates the fluid level from the time difference between the impulses sent and the impulses reflected.  The sensor can output the analyzed level as a continuous measurement reading through its analog output, or it can convert the values into freely positionable switching output signals.  TDR-Sensors are also known as Guided Radars or Guided Wave Radars.

34. Technique and Installation

35. Sensor Components Tracer 1000 & 2000 consist of three major components: 1. Housing 2. Feedthrough 3. Probe Parts exposed to tank: - Probe and the part of the feedthrough below the hexagon Housing - Contains the sensor’s electronics and input/output terminals Feedthrough - Mounted into the bottom of the housing and serves two main purposes: its outer threaded metal bushing securely connects the sensor to the tank and its inner components guide the high-frequency measurement signal from the electronics through the tank wall into the tank and back. Probe - Mounted onto the bottom of the feedthrough; the high- frequency measurement signal is propagated along the probe.

36. To meet various application requirements, Tracer 1000 has three different probe types: a single rod probe, a cable probe and a coaxial probe The probe design of Tracer 1000 & Tracer 2000 is fully modular, i.e. the probe types are interchangeable The single rod probe actually forms the inner conductor of the coaxial probe A standard ⅜" tube is mounted over the single rod probe and tightened with a very simple, yet safe, ferrule/locknut-style connection; similar to the ones widely used in standard tube fittings Probe Design

37. Single Rod / Cable Probe Suitable for a very wide range of applications The signal has a wider detection radius around the cable Thus, it is more responsive for measurement signal disturbances which can be easily overcome by observing a few mounting considerations and making simple configuration adjustments to the sensor The single rod probe is also recommended for installation in bypass chambers and stilling wells, which basically act together with the rod as a big coaxial probe. Cable Probe

38. In the coaxial probe, the high-frequency measurement signal is completely contained within the outer tube. Immune against any external conditions and interfering objects outside its tube Ideal solution for a hassle-free ‘drop-in anywhere’ installation; ensuring reliable measurement under almost any application condition. Ideal choice for measuring low reflectivity liquids (i.e. low dielectric constant) such as oils and hydrocarbons. Recommended for the use with clean liquids only NOT recommended with viscous, crystallizing, adhesive, coating, or sticky liquids; fibrous liquids, sludge, slurry, pulp; any liquids containing solid particles. Such liquids might cause build- up, bridging or clogging inside the coaxial probe. Coaxial Probe

39. Configuration Basic configuration of the Tracer can be done directly on the device via a DIP switch, a single push button and visual feedback from an LED All settings required to get Tracer 1000/2000 fully operational can be performed directly on the device Or Tracer 1000/2000 can be ordered completely pre-configured For greater convenience, remote configuration, and extensive diagnostics a simple Microsoft ® EXCEL spread sheet is provided through which the configuration can be done A standard HART modem is required for communication between computer and sensor Communication happens via a digital HART signal that is superimposed onto the analog 4-20mA signal of the current output
