Product Introduction:
The PPM-127E input type liquid level transmitter uses digital technology to collect real-time liquid level and temperature signals on the spot. After the CPU performs calculation compensation and parameter correction, it is converted by the D / A circuit into a high-precision two-wire system 4 ～ 20mA analog The signal and RS485 digital interface signal ensure the high precision and high reliability of the product. The level transmitter's zero point, full scale, unit, address and other parameters are open to users, so that when users need to adjust the product, or need to monitor multiple products at the same time, through RS485 interface and dedicated data cables and software , Perform on-site pressureless calibration and adjustment. This series offers customized services.
