Connecting rod type compound device for measuring temperature and liquid level

Abstract

The invention discloses a connecting rod type compound device for measuring temperature and a liquid level. The device comprises a base, a dial plate arranged on the base and provided with scale indicators, a rotation component arranged on the base, a pointer arranged on the rotation component and used for indicating scales on the dial plate, a linkage rod arranged on the rotation component and used for enabling the rotation component to rotate, a floating ball arranged at the tail end of the linkage rod and used for measuring the liquid level, a temperature sensor arranged on the floating ball and used for detecting the liquid temperature, a high-level microswitch and a low-level microswitch arranged on the base, an alarm part electrically connected with the high-level microswitch and the low-level microswitch, and an acquisition terminal electrically connected with the temperature sensor. The device provided by the invention can be used for monitoring the temperature of liquid at a top layer all the time, and the microswitches can be touched automatically to start alarm when a superior limit liquid level and an inferior limit liquid level are reached, so that the safety is improved.

Description

technical field [0001] The invention belongs to the field of metering and monitoring, and relates to a liquid level measuring device, in particular to a connecting rod type compound temperature and liquid level measuring device. Background technique [0002] With the rapid development of modern industry, various sealed containers and equipment are widely used. Correct monitoring of the liquid level and temperature of the liquid in the container or equipment is very important for the entire system. It is necessary to stably control the liquid level within a certain height range It is very important for the safety of the cooling and heat dissipation system to alarm at the limit position and monitor the temperature in real time. In the cooling and heat dissipation system, the liquid level of the coolant and the temperature of the top liquid level are related to the safety of the entire cooling and heat dissipation system, and even the entire large System security. [0003] In ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a connecting rod type compound temperature and liquid level measuring device, which solves the problem that the existing liquid level gauge cannot monitor the liquid level and temperature at the same time, can monitor the temperature of the top liquid, and can monitor the temperature of the upper limit liquid level. When the liquid level reaches the lower limit, the micro switch is automatically triggered to turn on the alarm, which improves the safety
