Winwon Chips
Temperature transmitter is usually used in conjunction with display instruments, recording instruments, electronic computers, etc. It can directly measure the temperatures of liquids, vapors, gases and solid surfaces during various production processes.
Thermocouple Principle: The working principle is based on the thermoelectric effect (Seebeck effect). When two different conductors form a closed circuit and a temperature difference exists between ends, a thermoelectric potential proportional to the temperature difference is generated.
Resistance Temperature Transmitter: The working principle is based on the physical property that the resistance value of a conductor or semiconductor changes with temperature. The transmitter converts the thermocouple and thermoresistor into standard electrical signals.
LQT2088/3051 Intelligent Temperature Transmitter
LQT2088 adopts an integrated design of transmission, measurement and display. Compared with traditional discrete digital display transmitters, it saves space and reduces installation difficulty. The product utilizes a 24-bits sigma-delta analog front end to ensure high precision. Enhanced security designs include anti-surge, anti-reverse connection, and multi-task scheduling optimization.
