The GJCL-15 Gap Sensor Cable for air preheaters is a device used to measure the gap of boiler air preheaters. The design principle is to calculate the size of the gap by measuring the pressure and temperature inside the preheater.

Specifically, the transmitter consists of two sensors: a pressure sensor and a temperature sensor. These sensors are installed at the inlet and outlet of the preheater to measure the pressure and temperature at the inlet and outlet. In addition, the transmitter also includes a microprocessor to calculate the gap size and output the corresponding signal.

During operation, air flows through pressure and temperature sensors through the preheater. These sensors transmit the measured data to the microprocessor, which calculates the size of the gap by comparing the differences in inlet and outlet pressure and temperature. The calculated gap size will be output in the form of an electrical signal for the monitoring system to record and process.

Overall, the design principle of the air preheater gap measurement transmitter is based on measuring the internal pressure and temperature of the preheater to calculate the gap size. The application of this equipment can help maintenance personnel detect and repair the preheater gap in a timely manner, ensuring the normal operation of the unit.
