Milltronics ILE-37 Sensing Head The Milltronics ILE-37 sensing head is an out-of-process sensing element for A, E, V, and C series solids flowmeters. It is used for continuous in-line weighing of powdered or granular dry bulk solid materials. The material is directed toward the sensing plate. The horizontal impact force of the material, deflecting the sensing plate, displaces the core of the sensing head LVDT (linear variable differential transformer). -

After you have removed and replaced the range spring, recalibrate the flowmeter and integrator. (See the Integrator manual, CALIBRATION section, for details.) Perform the LVDT output zero procedure. Perform an integrator zero and span calibration. Perform a span Adjust and factoring as required. 7ML19985CW01 Milltronics ILE-37 – INSTRUCTION MANUAL Page 13... -
Page 18: Troubleshooting
Troubleshooting Every Milltronics ILE-37 sensing head is subjected to extensive quality assurance procedures to ensure the highest possible degree of quality, reliability, and performance is achieved. The following listing indicates the probable cause, and proper course of action to be taken should the specified fault symptom occur. -
Page 19: Linearity
Some integrators are equipped with a linearization function to compensate for non-linear material flow patterns. Stand-alone linearizing devices are also available for this purpose. Electronic linearization should not be used to correct non-linear test weight results. 7ML19985CW01 Milltronics ILE-37 – INSTRUCTION MANUAL Page 15... - Page 25 Notes...
