A static level is a precision instrument that measures the relative elevation of a change between two or more points. It is mainly used for monitoring vertical displacement and tilt of basal surfaces such as dams, power stations, high-rise buildings, foundation pits, tunnels, bridges, and subways. The static level system is generally installed on the contour line of the horizontal or vertical base of the object to be measured. Usually, the integrated module automatic measurement unit collects data and then connects to the computer or control system through wired or wireless means. Measurement and control functions.
During the use of the static level, the containers of the multiple static level are connected by a liquid pipe, so that we can know that the liquid level of all static level is always at the same height in the horizontal direction, when the static level base is initially When the height is different or the base of different measuring points changes, the height of the static level is different, and the level of each static level is different from that of the own level. The static level is measured relative to the height of the liquid level. , can accurately reflect the relative height changes of each measurement point.
For the measurement of the liquid level surface, the liquid level sensor made by the principle of magnetostriction is used to measure the liquid level surface in real time and continuously. The structure of the liquid level meter is relatively complicated and the price is relatively high. Here we introduce a liquid level sensor made by optical principle to measure the liquid level. This optical liquid level sensor can sense the liquid level reaching a certain elevation and send an electric signal, so in the static level we As long as the corresponding level sensor is installed at the elevation of the alarm, the desired measurement and monitoring effect can be achieved, and the liquid level sensor can be installed at different specific elevations according to actual needs, and the pre-alarm can be performed to make the monitoring alarm system More reasonable.
The Honeywell LLE Series Enhanced Level Sensor contains a photo-trigger circuit that outputs a switching signal indicating presence/absence of liquid level. The liquid level sensor operating mode is the internal light reflection principle of the sensor. A light-emitting diode (LED) and a light-receiving transistor are included in the dome of the front end of the sensor. When there is no liquid, the light is reflected to the receiving tube through the top of the ball. When there is no liquid, the light is partially refracted inside the ball to the inside of the ball, causing the output of the receiving tube to change. This liquid level measuring method can instantly reflect the liquid level change. .
