Product Description

Overview

UHS-600 series float type liquid level switch is a liquid level control alarm product developed according to foreign advanced product technology. This product has the characteristics of reasonable structure and high reliability. It is suitable for various high temperature, high pressure and open containers in the process of aquatic products in petrochemical, electric power, food, pharmaceutical and other industries.

This product mainly uses the balance between the gravity generated by the float (float) and the father and son of the float (float) of the whole movable part, and realizes the relative displacement through the spring, drives the magnetic steel movement, and makes the magnetic switch action, so as to send out the control signal.

Working principle

float level switch

The buoy immersed in the liquid is subjected to the combined action of downward gravity, upward buoyancy and spring force. When these three forces are in equilibrium, the pontoon rests in a certain position. When the liquid level changes, the buoyancy of the buoy is changed accordingly, and the equilibrium state is broken, which causes the elastic force to change, that is, the expansion and contraction of the spring, so as to achieve a new balance. The expansion and contraction of the spring causes displacement of the magnetic steel which is rigidly connected to it. In this way, the liquid level is indicated by the magnetic induction element and the transmission device in the indicator. The alarm function of the liquid level signal can be realized by the instrument of the limit switch.

Based on the principle of displacement measurement, the displacement cylinder suspended on the measuring spring is immersed in the measured liquid and is subjected to the upward buoyancy of Archimedes, and its force is proportional to the mass of the discharged liquid. According to the liquid level, the immersion depth of the cylinder is different, the upward buoyancy changes, and the measuring spring will be extended accordingly to achieve the measurement result.

float level switch

Measuring element type floating ball, when the liquid level changes, the floating ball and the liquid level change synchronously, the magnetic shaft sleeve is rigidly connected with the floating ball, the liquid level rises and falls, the shaft sleeve rises or falls, enters or moves away from the magnetic steel action area, the magnetic steel is attracted or disconnected, and the micro switch acts to output the control signal.

Reed-resistance type remote transmission transmitter is a supporting instrument of UHS-A series magnetic level gauge, which is used to convert the liquid level of medium into 4 ~ 20mA standard current signal output. The sensor part of the transmitter is encapsulated in the magnetic turn-over column panel or externally bundled, with reasonable product structure and convenient installation. At the same time, the Japanese ALEPH dry reed switch is used as the sensing element, which has good product stability and long service life. It is a convenient and reliable liquid level transmitter matched with the magnetic turning column liquid level gauge. In addition, the transmitter output can be used with the light column indicator digital display adjustment alarm produced by our company to easily realize the display, control, adjustment and alarm of the liquid level.
