Abstract
The utility model relates to a thermostatic bath with a multi-point zero setting function. The thermostatic bath with the multi-point zero setting function comprises a thermostatic bath cavity (1), a heater (2), a thermometer (3), a temperature sensitive platinum resistor (4) and a temperature controller (6). The heater (2) is arranged in the thermostatic bath cavity (1) and is electrically connected with the temperature controller (6). The thermometer (3) is arranged on the upper part of the thermostatic bath cavity (1), the temperature sensitive platinum resistor (4) is arranged on one side of the thermostatic bath cavity (1), and a multi-point zero setting module (5) is arranged between the temperature sensitive platinum resistor (4) and a circuit connected with the temperature controller (6). The multi-point zero setting module (5) can calibrate temperature conducted from the temperature sensitive platinum resistor (4) to the temperature controller (6) so that the error between the temperature displayed by the temperature controller (6) and the actual temperature inside the thermostatic bath cavity (1) is reduced.
Description
Technical field
The utility model relates to a kind of bulb, relates in particular to a kind of transformer winding temperature gage and uses bulb.
Background technology
The effect of thermostat is the resistance signal that receives temperature element output through temperature controller; The corresponding temperature of resistance signal of comparison design temperature and temperature element output; Control heater heats or stops heating then, thus the temperature in the control thermostat cavity.The temperature-sensitive RTD of tradition thermostat directly is electrically connected temperature controller, because temperature element is influenced by circuit and external environment condition etc., causes the displays temperature of temperature controller and the actual temperature in the thermostat cavity to have deviation.Therefore, how farthest reducing the displays temperature of temperature controller and the error between the actual temperature in the thermostat cavity is the target that those skilled in the art pursue.
Summary of the invention
The utility model pin technical problem to be solved is the deficiency to traditional thermostat, and a kind of thermostat with multiple spot zeroing function is provided.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
Thermostat with multiple spot zeroing function comprises the thermostat cavity, heater; Thermometer; Temperature-sensitive RTD and temperature controller, said heater are located in the thermostat cavity and with temperature controller and are electrically connected, and said thermometer is located at thermostat cavity top; The temperature-sensitive RTD is located at thermostat cavity one side, between temperature-sensitive RTD and circuit that temperature controller is connected, is provided with multiple spot zeroing module.
Technical scheme according to the utility model; Between temperature-sensitive RTD and temperature controller connecting circuit, set up a multiple spot zeroing module; Multiple spot zeroing module can be calibrated the temperature that the temperature-sensitive RTD passes to temperature controller; Thereby temperature displayed on the calibration temperature controller solves the displays temperature of common thermostat existence and the problem that there is deviation in actual temperature.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
EmbodimentAs shown in Figure 1, have the thermostat of multiple spot zeroing function, comprise thermostat cavity 1; Heater 2, thermometer 3, temperature-sensitive RTD 4 and temperature controller 6; Said heater 2 is located in the thermostat cavity 1 and with temperature controller 6 and is electrically connected; Said thermometer 3 is located at thermostat cavity 1 top, and temperature-sensitive RTD 4 is located at thermostat cavity 1 one sides, on temperature-sensitive RTD 4 and circuit that temperature controller 6 is connected, is provided with multiple spot zeroing module 5.
This thermostat in use, temperature-sensitive RTD 4 is imported multiple spot zeroing module 5 with resistance signal, through 5 conversions of multiple spot zeroing module, calibration output current signal, temperature controller 6 obtains current signal and displays temperatures.
Owing on temperature-sensitive RTD 4 and circuit that temperature controller 6 is connected, be provided with the multiple spot module 5 that returns to zero; The temperature that multiple spot zeroing module 5 adjustable temperature-sensitive RTDs 4 are transmitted on the temperature controller 6, thus the displays temperature of temperature controller 6 and the error between the actual temperature in the thermostat cavity 1 reduced.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
