Magnetostrictive Level Transmitter Your Made-To-Order Solutions

The FineTek magnetostrictive level transmitter identifies the level of liquids and solutions with high precision and reliability. Absolute positioning output and no calibration required after power failure. Stability and reliablity. Ease installation without calibration & maintenance. Prompt response time, high resolution & high accuracy. Durable structure, dust-proof, withstands high pressure. Oil/water dual level indication. The Max. operation temp. is 200BC. EG3 adopted loop power structure for wire saving. Explosion-proof model available for hazardous environments. Housing of EG3 is...

OPERATING PRINCIPLE CONVERSION FORMULA The sensor mainly consists of magnetorestrictive wires sealed in a stem/rod and a permanent magnet sealed into a float that can move up and down the stem.Electrical current travels along the wires in the stem creating an axial magnetic field. When the float’s and stem’s magnetic field intersect, a torsional force is created with different height levels (see right). The sensor measures the liquid level (D) by calculating the elapsed time between torsional forces. Using velocity and time, distance can be calculated.This action is timely and continuous. A...

Loop Power 24Vdc ±10% The product is calibrated before shipment and should be sufficient to meet user needs. Do not bend the stem, put pressure on it or force it in any manner. For best results, use the included float only. 5. When the mounting hole is large enough, guide the stem and float through the hole to install. 6. If the hole is NOT large enough, remove float, install the stem and assemble float from inside the container. 7. When assembling the float onto the stem, the float's direction mark should face the housing. 8. Ensure the float stopper is fixed firmly. 9. If the stem is bent...
