Abstract
A thermal diffusion type liquid level switch comprises a wire connecting box (1) and a signal process unit (2), which is characterized in that the wire connecting box (1) is abreast connected with a heating rod (4) and a temperature sensing rod (5) through an installation thread (3). Thus the utility model has compact structure, convenient assembly and reliable performance, particularly is suitable for liquid level alarm of various liquid and interfacial checking of oil-water separation, etc.
Description
The utility model relates to a kind of switch, particularly a kind of thermal diffusion type liquid-level switch.
At present, the liquid-level switch that China uses mostly adopts the magnetic switch, and mainly there are shortcomings such as physical dimension is big, installation inconvenience in this magnetic switch.
The purpose of this utility model is exactly the thermal diffusion type liquid-level switch that a kind of compact conformation, easy for installation, dependable performance will be provided.
The purpose of this utility model is achieved in that a kind of thermal diffusion type liquid-level switch, form by terminal box (1), signal processing unit (2), it is characterized in that described terminal box (1) is connected to heating rod (4), sensing rod for temperature (5) side by side by screw thread (3) is installed.
The utility model compared with prior art has the following advantages: owing to adopt terminal box (1) to be connected to the form of heating rod (4), sensing rod for temperature (5) side by side by installation screw thread (3), thereby compact conformation, easy for installation, dependable performance.
Accompanying drawing and drawing explanation:
Fig. 1: be the utility model concrete structure schematic diagram
1, terminal box 2, signal processing unit 3, installation screw thread 4, heating rod
5, sensing rod for temperature
Embodiment:
Terminal box (1) adopts aluminum alloy materials to make; Heating rod (4) shell is a stainless steel material, and thermo electric material is equipped with in inside; Sensing rod for temperature (5) shell is a stainless steel material, and thermistor is equipped with in inside; Screw thread is installed to be made by stainless steel material; Heating rod (4) and sensing rod for temperature (5) are connected on the installation screw thread (3) side by side by the connecting thread of self, and installation screw thread (3) is connected on the terminal box (1) by the connecting thread of self.
During use, heating rod (5) is in heated condition always, there is not temperature measured under the situation of medium around as set point with sensing rod for temperature (4), when medium submergence heating rod (4) and sensing rod for temperature (5), by thermal diffusion, sensing rod for temperature (5) has been experienced variation of temperature, it gives signal processing unit (2) with the signal of variations in temperature, signal processing unit (2) can judge by comparing with set point whether liquid level exists, and switching signal is sent in decision.Otherwise, can not submergence heating rod (4) during when medium with sensing rod for temperature (5), then sensing rod for temperature (5) temperature reduces, signal processing unit (2) by with set point relatively, make corresponding switch motion once more.
Claims (1)
1, a kind of thermal diffusion type liquid-level switch is made up of terminal box (1), signal processing unit (2), it is characterized in that described terminal box (1) is connected to heating rod (4), sensing rod for temperature (5) side by side by screw thread (3) is installed.
