- Chemically resistant PVDF sensor.
- W band FMCW radar yields narrow beam with small antenna for superior performance in short range applications.
- Approved for open air applications outside of a tank.
- Compact design fits in limited space installations.
Application
SITRANS LR140 is a W band FMCW radar level transmitter, packaged in a chemically resistant enclosure with PVDF sensor for years of trouble-free reliable measurement service.
4 to 20 mA loop powered, it provides accurate level measurement to ranges of 8 m (26 ft). Measurement is possible, non-intrusively, through plastic vessel tops for easy installation. Programming is convenient using the Bluetooth connection and SITRANS mobile IQ application on your smart device.
It operates by emitting powerful high-frequency microwave pulses from its transducer. These pulses journey through the air or vapor medium hovering above the liquid or solid substances stored in tanks, silos, or other vessels.
Once they strike the surface of the material being measured, they rebound back to the transducer. LR140 uses the time-of-flight principle to calculate the time the pulses take to travel to the surface and return. Then it accurately determines the distance between itself and the material's surface. Incorporating additional parameters like the installation height, it then precisely computes the level of the substance.
LR140 combines advanced technology, durability, and versatility to meet the demands of modern industrial applications as a top-tier radar level measurement device.
