Product Highlights

The LMP331i Level Transmitter offers excellent performance and versatility for pressure measurement applications. With a nominal pressure range from 0 … 400 mbar up to 0 … 40 bar, it can accurately handle a wide range of pressure levels. The transmitter provides two output signal options: a 2-wire configuration offering a 4 … 20 mA signal and a 3-wire setup providing a 0 … 10 V signal. Other output signal options are available upon request. The LMP331i boasts impressive product characteristics, including minimal thermal error within the compensated temperature range of -20 … 80 °C, with a deviation of only 0.2 % FSO (full-scale output) and a temperature coefficient of just 0.02 % FSO / 10K. It also offers a remarkable turndown ratio of 1:10, allowing for increased flexibility in various applications. Additionally, the transmitter features a communication interface that enables easy adjustment of offset, span, and damping. Optional versions of the LMP331i include IS-versions (Ex ia) for intrinsically safe usage with gases and dust, as well as the ability to customise the nominal pressure ranges through factory-provided adjustments. Overall, the LMP331i Level Transmitter delivers accurate and reliable pressure measurement with advanced features and optional configurations to suit diverse industrial needs.
