Specifications: LMK 307 Stainless Steel Probe
The LMK307 Level Transmitter is a versatile and reliable instrument designed for accurate measurement of liquid levels. With a nominal pressure range from 0 … 4 mH2O up to 0 … 250 mH2O, it caters to a wide range of applications. The transmitter offers two output signal options: a 2-wire configuration with a 4 … 20 mA signal, and a 3-wire setup with a choice between 0 … 20 mA and 0 … 10 V signals. Its compact diameter of 27 mm makes it suitable for installations with limited space.
The LMK307 boasts good linearity, ensuring precise and consistent measurements, while its excellent long-term stability ensures reliable performance over extended periods. Handling the transmitter is effortless, adding to its user-friendly nature. Furthermore, the LMK307 is available in various optional versions, including an IS-version that is intrinsically safe for gas and dust environments, and it is compliant with SIL 2 (Safety Integrity Level) according to IEC 61508 / IEC 61511 standards. Customers can also choose from different types of cables and elastomers, as well as request customised versions to meet their specific pressure range requirements.
Applications
The LMK 307 Stainless Steel Probe is widely used in water applications due to its robust design and high resistance to corrosion. It is ideal for monitoring water levels in drinking water systems, ground water wells, and storm water management infrastructure. Its stainless steel construction ensures that it can be safely used in potable water environments without risk of contamination, while its slim profile allows for easy installation in narrow boreholes or tanks. Accurate pressure measurement in these settings is essential for maintaining water supply, managing resources, and preventing flooding.
In the field of sewage, the LMK 307 is engineered to withstand the harsh and aggressive conditions found in waste water treatment plants, water recycling facilities, and dumpsites. The probe’s durable materials and reliable sealing protect it from the corrosive and contaminated media typical in sewage systems. It provides precise level and pressure data, which is crucial for process control, system safety, and environmental compliance. Its resistance to fouling and clogging makes it a dependable choice for continuous operation in these challenging environments.
For fuel and oil applications, the LMK 307 is suitable for use in fuel storage tanks, tank farms, and biogas plants. Its stainless steel construction offers excellent compatibility with hydrocarbons and other aggressive substances, ensuring long-term stability and safety. The probe delivers accurate level measurements that are vital for inventory management, leak detection, and process optimization in fuel and oil storage. Its robust design minimizes maintenance needs and supports reliable operation even in demanding industrial settings.
