BD Corporation Gauge Pressure Corrosion-Resistant Pressure Sensor LMK331 Series
BD Company Gauge Pressure Corrosion-Resistant Pressure Sensor LMK331 Series
LMK331 is a sensor with excellent corrosion resistance. The pressure port uses PVDF and is a flush diaphragm type pressure sensor.
The BD company's LMK331 sensor is a sensor with excellent corrosion resistance. It is designed with advanced electronic circuit technology and compactly housed in a case. The pressure port uses PVDF, and the diaphragm is a capacitive pressure sensor made of alumina ceramic. The joint part is manufactured with a G3/4 connection, and the tip features a flush diaphragm structure with minimal dead volume. The compensation temperature range is -25 to 85°C, and it can be used with media at temperatures from -40 to 125°C. The measurement accuracy is ±0.5% FS, and the output signal can be selected from 0-10 VDC or 4-20 mA. The measurement mode is gauge pressure, with a low-pressure range of full scale 40 kPa to a high-pressure range of up to 2.5 MPa, and a rich pressure range of up to 6 MPa with a stainless steel diaphragm. The protection rating is standard IP65, with an option for IP67. CE compliance is EN61326, and 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.
