1. Product features and uses: equipped with JA and JB grades for precision water conservancy and hydrological measurement. General industrial and civilian water tank measurement and control use MA, MB level, and low-cost civilian water tank measurement and control use L level.

CYG2314 JA and JB levels are suitable for water conservancy and hydrological measurement in northern regions. They use imported original components and industrial grade precision instrument discharge circuits, and are equipped with simplified lightning protection circuits that can withstand transient high-voltage pulse damage from general induction lightning up to 50 meters away with a strength not exceeding 2kV/1kA. It is not inferior to CYG2316 in measurement accuracy, only slightly inferior in lightning resistance, temperature drift additional error, and time drift additional error.

CYG2314 MA and MB levels are suitable for general industrial and civilian liquid level measurement and control purposes. It uses high-quality components and industrial grade instrumentation circuits produced by Sino foreign joint ventures, and has high accuracy. But it does not have lightning protection function, and the built-in low-power high-speed discharge device can only be used to discharge transient high-voltage low-energy pulses induced by lightning far away or nearby electrical equipment to protect the instrument discharge circuit (i.e. the lightning protection function generally understood by people). Due to the additional error caused by long-term drift, it is economically practical for measurement and control purposes that require practical accuracy to remain at a level of 1-2% after 1-2 years, and the maintenance cost of the system manufacturer is low, making it economically practical. But it is not recommended for measuring purposes with high requirements.

The CYG2314L product is designed specifically for the purpose of low-cost measurement and control of water level in civilian water tanks. It is manufactured using domestically produced pressure sensitive components and equipped with a good operational amplifier circuit. Medium precision, able to ensure 2-3% usage accuracy within 2 years, with high cost-effectiveness.

2. Range: 0-2, 3, 5, 10-200 mH2O or measured in kPa

3. CYG2314, CYG2304 accuracy level:

Note: ⑴ The parentheses represent the indicators of low range products with a range of 1-3 meters, which should be relaxed according to international practice.

⑵ CYG2314J grade are all integrated products, and to ensure lightning protection performance, they do not accept split transmitter types.

CYG2314 M-grade, L-grade, and CYG2304L can supply split type transmission.

If only sensors are needed, the performance and price will be negotiated separately.
