Reserve level gauge | tank high level alarm | High stability reserve level gauge structure and working principle of a reserve level gauge of fiber optic liquid level sensor probe fiber optic sensor probe by high-precision optical coupler and the optical path adjustment device composition, receives an optical signal and the level of data gathering, will be collected by the fiber level value is sent to the controller. The probe is mounted on top of the tank, the site is using optical signals without any electrical, intrinsically safe. 2, the reserve level gauge sensor is controlled by the power control terminal, fiber optic liquid level sensor module, the converter board and the display composition, which is responsible for the optical signal modulation and demodulation, by demodulating the optical signal to be level signal into an electrical signal. The controller has a system initialization, historical data query, channel settings, time settings, and restore factory settings and other functions, with 4 ~ 20mA output, RS232, RS485 and GSM module can be transmitted through the communication module level information to industrial control systems, computers and monitors, etc., to achieve the level of data displayed. Reserve level meter Features: 1, different from the older generation reserve level meter using optical encoder to calculate the level of our company currently popular fusion technology and fiber-coupled laser ranging technology for level measurement and signal transmission, so so that the whole structure of the instrument is more compact, higher accuracy, better stability, installation and maintenance easier. 2, reserve gauge transmit signals using optical fiber transmission distance, anti-interference ability, measurement site is not charged, absolute security proof 3, high reserve level gauge measurement accuracy up to ± 3mm, measuring range up to 25m 4 reserve level gauge is easy to install, no clear tank, no flare, convenient and safe 5, reserve level gauge modular design, the overall package, high reliability, and low failure rate. 6, a wide range reserve level gauge can be used to measure various types of tanks and tank group turnover tank. 7. Reserve gauge integrated interface RS485, RS232, RJ45,4-20 mA signal output interface. For more detailed information on the reserve level gauge, please call: Ms. Mei 027-50851666-619 QQ: 2871691174.
