I2C digital pressure sensors for water and gas network monitoring

The LD Series is the smallest fully functional OEM I2C digital transmitter for pressure and temperature measurement by KELLER.

The LD Series is the market leading sensor for gas and water pressure monitoring. These sensors have an accomplished real-life total error band of ±1.2mbar and resolution of 0.7mbar over -20°C… 70°C (100mbar sensor).

This performance enables equipment manufacturers to measure pressure data more accurately improving the quality and reliability of information to minimise gas/water leakage, ultimately reducing costs for utility companies.

All the electronic components are contained within the oil filled housing making the sensors easy for system integration. The I2C interface allows for multiple sensor monitoring and simple plug and play technology. The LD Series operates at pressure ranges from 0.1… 1000 bar and an operating temperature range from -40… 110°C. These sensors are fully factory compensated and have a low power consumption of 1.8… 3.6VDC. They come in an ultra-compact, robust housing made from stainless steel (optional Hastelloy C-276) and an intrinsically safe version is available.
