Description

An auxiliary device for liquid bath calibration

technical field

The utility model relates to the technical field of liquid temperature calibration, in particular to an auxiliary device for liquid bath calibration.

Background technique

The liquid bath is a common temperature heating equipment in the laboratory. Generally, water, alcohol, silicone oil and other media are used, and a standard platinum resistance thermometer is used for calibration. The platinum resistance thermometer has a slow stabilization time, and needs to be suspended in the liquid, and according to the regulations, it is necessary to measure multiple points on the same plane in the liquid. In actual work, the handheld instrument cannot guarantee the consistency of the measurement position and depth, and maintaining a posture for a long time will easily make the operator tired. In addition, when the temperature is high, the high temperature or water vapor may present a safety hazard to the hand.

Utility model content

The purpose of this utility model is to solve the deficiencies of the prior art and provide an auxiliary device for liquid bath calibration, comprising a platinum resistance thermometer, a base plate, the base plate is arranged above the liquid, the top of the base plate is provided with a top chute, and the base plate The side is provided with a side chute; a slider, the slider is arranged on the top of the base plate, and the slider can move along the chute on the top of the base plate; a clamp, the clamp is connected with the slider; a fixed baffle, the The fixed baffle is arranged in the base plate side chute, and the fixed baffle can move along the base plate side chute.

Further, an adjustment knob is provided on the clamp.

Compared with the prior art, the utility model has the advantages of:

1. The platinum resistance thermometer can be fixed in the working area without the need for a human to hold the standard, which ensures the consistency of the horizontal depth of the measuring point and avoids potential safety hazards;

2. The movement of the platinum resistance thermometer in the rectangular horizontal plane of the liquid bath equipment can be realized.

Detailed ways

The present utility model will be further described below with reference to the accompanying drawings. The structure and principle of the present utility model will be very clear to those skilled in the art. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not intended to limit the present invention.

1 and 2, the present invention is an auxiliary device for liquid bath calibration, comprising a platinum resistance thermometer, a base plate, a slider, a clamp and a fixed baffle plate, the base plate is arranged above the liquid, and the top of the base plate is provided with The top chute, the side of the base plate is provided with a side chute; the slider is arranged on the top of the base plate, and the slider can move along the chute on the top of the base plate; the clamp is connected with the slider; the fixed baffle is arranged on the base plate In the side chute, the fixed baffle plate can move along the side chute of the base plate.

In a preferred embodiment, the fixture of the present invention is further provided with an adjustment knob.

The structure and function of the above components are as follows:

1. Adjustment knob: turn to change the angle and strength of the fixture to meet the needs of different platinum resistance thermometers;

2. Fixture: used to fix the platinum resistance thermometer, the angle can be changed by adjusting the knob;

3. Top chute: used to guide the moving track of the slider so that it can move longitudinally in the horizontal plane;

4. Substrate: a component used to fix the entire device, which can span over the working area of the liquid bath equipment;

5. Slider: used to fix the fixture to realize the longitudinal movement of the platinum resistance thermometer on the horizontal plane;

6. Fixed baffle: used to fix the substrate above the working area of the liquid bath equipment to limit its longitudinal movement;

Side chute: It is used to guide the moving track of the fixed baffle, so that it can adapt to the working area of different widths.

The workflow of the present utility model is as follows:

To calibrate, the device was straddled over the liquid bath work area with the substrate longitudinally parallel to the work area. Fix the device by adjusting the fixing baffle so that it catches on the front and rear sides of the device. Clamp the platinum resistance thermometer with a clamp and adjust it to an appropriate height, and the reading can be read after the indication is stable. When it is necessary to adjust the position of the fixture on the horizontal plane of the entire work area, you can move overtime to adjust in the horizontal direction, and move the slider to adjust in the vertical direction.

In a specific embodiment, the cover of the water bath is removed, the device is longitudinally spanned over the liquid medium, and the water bath shell is clamped with a fixed baffle to keep the device stable. Place the platinum resistance thermometer deep into the liquid in a fixed position, and adjust the knob so that it is gripped by the clamp. Turn on the water bath, and after it reaches the set temperature and stabilizes, read the indication of the platinum resistance thermometer. Then it is necessary to measure the temperature of other locations of the liquid medium. Move the device laterally along the rectangular area, and then move the slider, so that the platinum resistance thermometer is positioned at another position on the plane, and read again after stabilization. Perform this step several times and perform calculations based on the measured values to complete the calibration.
