The LKB Bromma 2211 is a high-precision industrial pressure sensor developed by the Swedish LKB Bromma Group. It uses piezoceramic sensing technology to provide accurate, long-term stable pressure measurement for a wide range of industrial applications. The sensor is suitable for use in oil and gas, chemical processing, mechanical manufacturing, and food processing industries.
Measurement Range: 0-100 bar (expandable to 0-200 bar)
Accuracy Class: ±0.5% F.S.
Output Signals: 4-20 mA analog, RS-485 Modbus digital
Power Supply: 24 V DC (10-30 V DC wide range)
Operating Temperature: -20°C to +80°C
Protection Rating: IP67 (dust-tight and water-immersible)
Response Time: ≤100 ms
Material Compatibility: Stainless steel housing, corrosion-resistant (oil, water, acidic liquids)
Mounting: Threaded connection (M20×1.5) or flange mount
EMC Compliance: Industrial 4.0 standard, compatible with variable frequency drives and motors

The sensor utilizes a piezoceramic element that provides micro-scale deformation detection, combined with a temperature compensation algorithm to ensure long-term accuracy drift of less than 0.2%. The sensor supports zero and full-scale calibration via a handheld terminal or software. The fully sealed design allows operation in harsh environments, and the digital RS-485 Modbus output enables remote diagnostics of sensor status (overpressure, overtemperature alarms). An optional isolation diaphragm protects the sensing element from direct contact with corrosive media.
The LKB Bromma 2211 is used in oil and gas wellhead pressure monitoring, chemical reactor pressure measurement, hydraulic system control in manufacturing, and food processing equipment pressure monitoring. Its IP67 rating and wide temperature range make it suitable for outdoor and high-temperature installations.
