A barometric altimeter is a high-precision and highly intelligent pressure measuring instrument that uses pressure sensors to measure atmospheric pressure and calculates altitude based on the functional relationship between pressure and altitude. It has many advantages such as high measurement accuracy, good long-term stability, high reliability in use, and easy operation.

4. Product selection

FYM-GDXXX, XXX represents the sequence code of altimeter products, such as 001002, etc

Note:

1) The above product dimensions do not include connectors.

2) The cost price of the above products is only for the components and material costs of product manufacturing. If additional testing is required, it needs to be calculated separately.

The product can be applied in fields such as automotive, aviation, and meteorology, and can be customized and developed according to user needs.

Usage

1) Use a dedicated test cable to connect with the altimeter product's onboard plug and tighten it; Ensure reliable and correct electrical connections;

2) The power cord is connected to a 24V DC power supply (which can work normally within the range of 18VDC to 36VDC).

3) The data cable should be connected to an RS232 (or RS422) to USB adapter (the adapter model depends on the transmission form of the altimeter) and connected to a computer.

4) The "Serial Debugging Assistant" software allows real-time viewing of altimeter output data, with FYM-GD003, FYM-GD004, and FYM-GD006 outputting data in hexadecimal code format, and other altimeter models outputting data in ASCII code format. Please refer to the "User and Maintenance Manual" of each product for specific data format definitions.
