Introduction: In industries such as measurement, metallurgy, mechanical equipment manufacturing, etc., in order to achieve accurate measurement and precision control, it is usually necessary to perform precise calibration on temperature points above 300℃. Traditional constant temperature oil tanks have low temperature upper limits, and high temperature verification furnaces have poor temperature field performance. In response to weaknesses such as low thermal load capacity, Changfeng has launched a salt bath thermostat to achieve high-accuracy temperature sensor and transmitter calibration. The salt bath constant temperature tank adopts a new working principle. Compared with the constant temperature oil tank, the working upper limit can be increased from 300°C to 670°C; compared with the high temperature verification furnace, the salt bath constant temperature tank has a temperature field uniformity of 0.025°C. The equipment uses industrial-grade touch-sensitive computers, multiple heaters, and multiple temperature sensors. The application of homogenized salt, over-temperature protection, and sensor disconnection protection technology realizes fully automated salt temperature control, thereby ensuring the safety, efficiency and ease of use of the equipment. Features: 1. The highest upper limit is 670℃ liquid temperature source; 2. The temperature field fluctuation is better than 0.015℃/10min, and the temperature field uniformity is better than 0.025℃; 3. Support batch calibration of large head and short and short type sensors and transmitters; 4. Fully automatic salt, temperature control, safe and easy to operate. Technical parameter: Accuracy and measurement range: 0.1℃; 450℃～670℃ Fluctuation: ±0.01℃/10min @450℃ ±0.015℃/10min@670℃ Uniformity: Horizontal temperature difference: ≤0.01 ℃@450℃ Vertical temperature difference: ≤0.015 ℃@450℃ Horizontal temperature difference: ≤0.015 ℃@670℃ Vertical temperature difference: ≤0.025 ℃@670℃ Dimensions (mm): Shape (length, width and height): 900×700×(1060+250) Test cavity: Φ110×420 Power supply and power: (210~230)VAC, (45~65)Hz; peak value 3.5kW, typical 3kW Salt melting time: 3 hours at room temperature until the salt melts
