BD Company High-Precision Flash Diaphragm Pressure Sensor LMP331i
BD Company High-Precision Flush Diaphragm Pressure Sensor LMP331i
Measurement of gauge pressure and absolute pressure from a pressure range of 0 to 17 kPa to 3.5 MPa, with high accuracy of ±0.05% FS and a flush diaphragm in the wetted part.
The LMP331i from BD Corporation is a pressure sensor suitable for industrial applications that require high precision. It covers a pressure range from 0 to 17 kPa to 3.5 MPa with a rich selection of seven ranges. There are two measurement modes available: gauge pressure and absolute pressure, both capable of measuring with high precision of ±0.05% FS. Pressure is transmitted to the silicon cell through an oil medium applied to a flush diaphragm. The output from the silicon cell is temperature compensated and linearized for high precision output. The output signal can be selected from 0 to 10 VDC or 4 to 20 mADC. The pressure port is made of SUS316Ti, and the diaphragm is made of SUS316L, making it compatible with most media. An intrinsically safe explosion-proof type is also available as an option.

Company information
Air Water Mechatronics Co., Ltd. ST Division handles excellent measurement/control equipment focused on the most important themes of pressure and flow in the field of measurement and control in the industrial sector. In pressure measurement, as the Japanese distributor for Setra Systems, we have supplied numerous pressure sensors domestically for many years. Setra's pressure sensors are characterized by high precision and sensitivity, and are used in many advanced technologies, including semiconductor manufacturing equipment. Additionally, to accommodate various industrial pressure measurement scenarios, we also handle products from companies such as BD and Honeywell. We manufacture digital pressure gauges that incorporate or externally attach these pressure sensors. Within our company, various pressure standards with traceability to national standards are installed in a strictly air-conditioned calibration inspection room, allowing us to conduct inspections and recalibrations in-house. Regarding flow measurement, we offer unique and high-value-added products for both liquid and gas (mass flow). For liquids, we primarily provide small, cost-effective, and highly accurate turbine flow meters, as well as Coriolis flow meters. We respond to diverse needs with disposable sensors for pharmaceutical and medical manufacturing, as well as certified sensors for food and beverage applications.
