Sugar content ethanol concentration online monitoring cutting fluid concentration sensor

Online concentration sensorIt consists of a light source, sapphire refractor, receiver, and signal modulation circuit. The light source emits a stable light signal that passes through sapphire and comes into contact with the measured medium. The corresponding refractive index is generated by the concentration of the measured medium. The receiver calculates the refractive index of the collected refractive light source and obtains the corresponding concentration through data algorithms. Since the concentration is affected by temperature, internal temperature calibration is used to reduce the influence of temperature drift.

The key feature of an online refractometer is that it only measures the content of soluble substances in the liquid and is not affected by common factors such as particles, bubbles, crystals, and color in the process. Therefore, online refractometers are widely used in various industries to measure solution concentration or density in production processes.

General fault diagnosis and troubleshooting

When there is no signal output from the concentration meter, the first thing to check is whether the extended cable is broken or short circuited, or whether the working voltage of the concentration meter is normal

2. If there is suspicion of a malfunction in the concentration meter, the following methods can be used to check and determine. Remove the concentration meter and measure the concentration of water and a certain concentration of medium separately. Use a multimeter to measure the mA current range. The blue electronic wire: 4-20 outputs positive and the yellow electronic wire: 4-20 outputs negative. The current signal should be 4mA, and the current output corresponding to the measured medium is normal. Otherwise, the concentration meter is faulty.

Since its establishment in 1999, Shanghai Chaohui Pressure Instrument Co., Ltd. (referred to as ZHYQ) has been based on the research of four major physical quantities: pressure, flow rate, temperature, and liquid level. It has inherited decades of research and development technology and processes, and developed a series of large-scale and industry-specific measurement products. With products widely used in industrial control processes, engineering machinery, petrochemicals, water conservancy and many other fields, the market covers more than 50 countries and regions. It is a domestic manufacturer of industrial control pressure, flow, temperature, liquid level and IoT control products.

The company is gradually building into a group company, with one subsidiary in the UK, one subsidiary in Australia, and two subsidiaries in Shanghai. In 2016, ZHYQ established a 15000 square meter production base in Yueyang, Hunan.

At present, ZHYQ's customers have more than 1000 excellent users and 18 representative offices in China. With the rapid development of the Internet in recent years, ZHYQ's partners have expanded to the global market, and internationally competitive products have spread all over the world. ZHYQ is one of the earlier companies in the industry to obtain ISO9001 quality management system certification. The product has successively obtained domestic and foreign certifications such as CMC, Ex, MA, CE, RoHS, etc.
