Abstract
The utility model discloses a gas sensor constant temperature device. The device comprises a hollow gas chamber, a sensor and a heater, the gas chamber comprises a gas chamber base and a gas chamber upper cover, the sensor is fixed in the gas chamber base and is not in contact with the bottom of the gas chamber base, the gas chamber upper cover covers the top of the gas chamber base to seal the whole gas chamber, gas holes used for gas intake and gas vent are arranged on the gas chamber, and the heater is arranged on the outside of the gas chamber and tightly attached to the bottom of the gas chamber. The device has the advantages that the gas sensor is arranged in the constant temperature gas chamber so that when the gas to be detected enters the sensor, the gas can be maintained at the constant temperature, the effect of the temperature on the gas is reduced, the constant and controllable temperature of the gas to be detected in the sensor is guaranteed, the disturbance caused by the sensor in prior products is eliminated, compared with the measurement accuracy of prior detection instruments, by means of the gas sensor constant temperature device, the measurement accuracy is higher, and the accurate and reliable detection result is guaranteed.
Description
Technical field
The utility model relates to a kind of gas sensor thermostat.
Background technology
The various gas detecting instruments of commonly use at present when reality is used, often occur testing result fluctuate larger, particularly when the lower minimum gas of detectable concentration, indeterminacy, precision is low, has become the common fault of present detector.And cause the main cause of this phenomenon, when just being to detect, by gas sensor in the detector the gas temperature of examining non-constant, cause gas density to change, affected the gas testing result.
Summary of the invention
In order to solve the not good technical matters of present gas detecting instrument accuracy of detection, the utility model provides a kind of and guarantees that the gas detecting instrument accuracy of detection is high, detects and disturbs little gas sensor thermostat.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is, a kind of gas sensor thermostat, the air chamber, sensor and the well heater that comprise hollow, described air chamber comprises air chamber base and air chamber loam cake, and sensor is fixed in the air chamber base and does not contact the bottom of air chamber base, and the air chamber loam cake covers in the air chamber base top to seal whole air chamber, also have on the air chamber for air inlet and the pore of giving vent to anger, it is outer and be close to the bottom of air chamber that described well heater is arranged at air chamber.
Described a kind of gas sensor thermostat, described well heater is heating ceramic.
Described a kind of gas sensor thermostat, described air chamber is to be made by stainless steel.
Technique effect of the present utility model is, gas sensor is arranged in the constant temperature air chamber, so that gas to be measured can keep constant temperature when entering sensor, thereby reduced the impact of temperature on gas, the gas temperature to be measured of having guaranteed to enter sensor is constant controlled, thereby solved existing product because the interference that sensor brings makes measuring accuracy higher than existing detector, guaranteed that testing result accurately and reliably.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein 1 is that air chamber loam cake, 2 is that sensor, 3 is that air chamber base, 4 is well heater.
Embodiment
Referring to Fig. 1, the utility model improves temperature to the impact of sensor for emphasis, to installation of sensors Temperature-controlled appliance, sensor is worked under constant temperature, thereby temperature reduces to minimum to the impact of sensor.It comprises air chamber, sensor and the well heater of hollow, air chamber comprises air chamber base and air chamber loam cake, sensor is fixed in the air chamber base and does not contact the bottom of air chamber base, the air chamber loam cake covers in the air chamber base top to seal whole air chamber, make sensor not be subjected to ectocine, also have on the air chamber for air inlet and the pore of giving vent to anger, well heater is arranged at outside the air chamber and is close to the bottom of air chamber, directly do not contact with sensor, the centre is separated by corrosion resistant plate, has avoided the heating ceramic infringement that directly heating causes to sensor.Well heater is heating ceramic, considers mainly that with ceramic heat ceramic heating flake power consumption and security are relatively good, and heat conductor relatively relaxes, and helps to keep temperature constant in the air chamber.Air chamber is to be made by stainless steel, to guarantee preferably heat-transfer effect.
Claims (3)
