AT300 constant temperature tank

1 meet the standard:

1.1 zby172-83 technical conditions for standard oil tank

1.2 JJG130-2004 "working glass liquid thermometer calibration procedures"

 

2 main technical indicators:

Operating temperature range: 2.1 + 50 ℃ ~ + 300 ℃.

2.2 temperature volatility: plus or minus 0.01 ℃ / 30 min or less.

Temperature uniformity: 2.3 plus or minus 0.01 ℃ or less;Vertical plus or minus 0.02 ℃ or less.

2.4 studio size: phi 160 mm x 550 mm.

2.5 insulation thickness: > 100mm.

2.6 insert dial:

2.6.1 a set of large hole inserts for a glass thermometer with the diameter of phi 16 mm;

2.6.2 the middle hole and the hole insertion dial are in a set, the middle hole is suitable for the external diameter phi 11 mm glass thermometer, the hole is suitable for the external diameter phi 6 mm glass thermometer;

2.6.3 each set of inserts is divided into two layers, each of which has shrapnel, which effectively ensures that the thermometer is vertical when used.

2.10 standard medium: imported methyl silicone oil kf-50 (far better than 201-50)

2.11 channel volume: 25L;Storage tank capacity 45L

2.12 oil system: yes

2.13 anti-combustion function: yes

2.14 power supply: 220V/ 50Hz.

2.15 power: about 3KW.

2.16 dimensions: length x width = about 550 x 760 x 1250mm

2.17 noise: no more than 60DB

3. Working conditions:

3.1 working voltage: 220V plus or minus 10%

3.2 power frequency: 50Hz + 1Hz

35 ℃ ambient temperature: 3.3 or less

3.4 environmental humidity: 20% ~ 85%. 

4. Measurement and control system:

4.1 temperature sensor: Pt100 platinum resistance

4.2 control instrument: high resolution microcomputer control instrument

4.3 adjustment mode: PID, the microcomputer adjusts the PID according to the setting temperature and the measured temperature, and the temperature and change in the tank are controlled by adjusting the heating power.

4.4 overload protection: when the current of the power supply is too large, the overload protection automatically starts, cutting power, so as not to cause the accident.
