Description

A kind of sensor for solar water heater
Technical field
The utility model relates to sensor field, is specifically related to a kind of sensor for solar water heater, for detecting the change of water temperature and water level in solar water heater.
Background technology
Sensor for solar water heater is a kind of change for detecting water temperature and water level in water heater.Usually there is problem in present sensor for solar water heater: 1, the detection of sensor for solar water heater is subject to the disturbing effect of water quality, incrustation scale etc., and the data of collection are accurate not, had a strong impact on the control accuracy of controller; 2, sensor needs long-term work among water-heater water tank, because the heat of vacuum tube is large, passes to a lot of heat of water-heater water tank, make water tank temperature can reach about 100 degree for a long time, short time can reach 130 degree, and even 150 degree, this just brings high temperature resistant problem to sensor; 3, temperature-sensing probe is generally all directly contacted water source with water-level probe by sensor for solar water heater, leaks and causes sensor failure; 4, because China's water quality differs, the quality problem in a lot of area is very serious, and incrustation scale brings a lot of trouble to sensor, and incrustation scale is attached on electrode and temperature-sensitive block, causes sensor senses water-level and water-temperature inaccurate.So high temperature resistant, resistance to incrustation scale, sealing are insoluble difficult problems always.
Utility model content
An object of the present utility model is, provides a kind of sensor for solar water heater, solves the impact of hot environment on sensor.
Above-mentioned purpose of the present utility model and other objects solve by the following technical programs:
The utility model provides a kind of sensor for solar water heater, comprise level sensor, cooling-water temperature sensor, silica gel terminals, it is characterized in that, described level sensor is provided with 4 level sensor modules and 4 sensing probes, a corresponding sensing probe of level sensor module, the length of 4 sensing probes is inconsistent, and it is inner that described level sensor module is fixed on silica gel terminals, and described sensing probe inserts silica gel terminals and is connected with described level sensor module 4; Described cooling-water temperature sensor comprises water temperature sensing module, stainless-steel tube, and described stainless-steel tube is fixed on silica gel terminals, and described stainless-steel tube inside is provided with water temperature sensing module and silica gel sheath, and described silica gel sheath and described stainless steel inside pipe wall fit tightly.
The one that the utility model provides is for sensor for solar water heater, and preferably, described water temperature sensing module is thermistor.
A kind of sensor for solar water heater that the utility model provides, preferably, described sensing probe is cylindrical probe, and described sensing probe adopts the stainless steel of corrosion-resistant easy conduction to make.
A kind of sensor for solar water heater that the utility model provides, preferably, described stainless-steel tube 7 upper end is provided with a nut.
Advantage of the present utility model and beneficial effect are: adopt said structure, described level sensor is provided with 4 level sensor modules, 4 level sensor modules are placed in silica gel terminals, can be good at avoiding sensing module directly to contact with the water of high water temperature, even if there is a sensing module to be burnt out by high temperature in the case of a high temperature, other can also normally work; Water temperature sensing module is placed in stainless-steel tube inside simultaneously, and stainless steel inside pipe wall is provided with silica gel sheath, makes the transmission of heat have a progressive process, avoids and raise in the water temperature sensing module Yin Wendu short time and burn out.
