Description
SBEM’s ProWave80G Series – Model 138 W83 is a precision-engineered 80GHz FMCW radar level transmitter designed for highly accurate level measurement in corrosive liquid applications such as acid tanks, H₂SO₄ tanks, and chemical dosing systems. With a maximum measuring range of 60 meters and exceptional accuracy of ±2mm, the 138 W83 offers superior performance in challenging industrial environments. It features a narrow beam angle (3° or 8°), IP67-rated aluminium housing, and SS+PTFE antenna material, making it ideal for harsh and corrosive conditions. The device supports a 2-wire 24VDC power supply with an analog 4–20mA and optional HART output for seamless system integration. Its real-time 128×64 dot matrix display enhances visibility and monitoring. Designed with flanged installation, multiple cable entry options (PG11 or ½” NPT), and process temperature support up to 200°C, SBEM’s 138 W83 ensures reliability and durability in the global chemical, power, and fertilizer industries. It is available in two temperature variants up to 85°C and 200°C.
Features
- Accurate Level measurement: The high frequency of ProWave80G radar enables accurate distance measurement, making it ideal for applications such as distance sensing and object tracking.
- False echo suppression: False echo suppression improves the accuracy of radar measurements by filtering out unwanted signals that may cause inaccuracies.
- Narrow Beam Angle: Provides larger range and supports smaller diameter vessels. The interface in the installation environment has less impact on the instrument, making it easier to install and more suitable for mixing conditions.
- Display: A radar display provides real-time visualization of detected objects and their attributes, aiding in navigation, surveillance, and safety, enhancing situational awareness and decision-making.
- IP Rating: IP67 Ingress Protection for radar ensures it’s sealed against dust, making it durable and reliable in outdoor and harsh environments, enhancing its longevity and performance.
