MAGNETOSTRICTIVE LEVEL TRANSMITTER

Transcription

1 MAGNETOSTRICTIVE EVE TRANSMITTER http: // Tel: Fax: EG series Magnetostrictive evel Transmitter is built based on the principle of magnetic field interaction of two different directions, which sends out a signal to determine the exact level of the medium. Therefore, even if there is a power failure and reconnection is needed, it will not affect the previous setting parameters. So there is no reconfiguration involved. Moreover, medium is not in contact to the sensing element. There will be no wear and tear to the sensing element during repeat operation. As Magnetostrictive evel Transmitter gives direct signal output, additional output interface is not needed. As the resolution is very accurate and reliable, it will reduce the malfunction of the product. Moreover, due to the durability of the sensing element, Minimal maintenance is needed, Thus stocking for replacement parts inventory is not needed. For PC connection, it enables long distance monitoring of one EG transmitter ( use RS3 / RS485 communication port) or multiple EG transmitters (use RS485). (RS 3 / RS485 are optional accessories). FEATURES. High performance.. Absolute position output. Prompt response time.. High stable & high reliable.. Multi output selection.. Easy installation & no periodic maintenance. High resolution & high accuracy protection rating.. Durable structure with IP66. APPICATION 4 Natural gas liquid medium. 4 Pharmaceutical / beverages 4 Water Dam / barrier. 4 Water / Wastewater Treatment. 4 Chemical Process. 4 Crude oil / Oil industry. 4 Normal liquid environment.

2 OPERATING PRINCIPE Magnetostrictive Transmitter measures the accurate medeum (D) by calculating the time travel of signal formed by two different magnetic field. One magnetic field comes from the float ball, and the other comes from the current pulse given by the waveguide tube. When the pulse signal is reversed back to the waveguide coil, the transmitter will calculate the float ball (liquid level) based on the time interval and travel speed the pulse signal between the two magnet field. This action is coatinuous and timely. The change float position will be detected promptly with absolute signal output.

5 INSTAATION RECOMMENDATION Power supply is 4VdcK0% This product will be calibrated before shipment. It is recommended not to change the actual measurable length. Please make sure the float arrow faces toward the housing when reinstalling Please do not bend the stem to ensure the measuring accuracy and performance. Please do not change a different float to auoid the effect of measuring accuracy. WIRING INSTRUCTION Terminal Wiring Diagram ( Green ) 1.
