Siemens Radar transmitters
Sitrans LR 460: 4-wire, 24 GHz FMCW radar level transmitter for continuous monitoring of solids in silos to a range of 100 m (329 ft).
Siemens radar transmitters are easely installed and operated, they save time and money. Unlike the ultrasonic principle, the radar technology does not require a carrier medium and the microwaves propagate at the speed of light (300,000,000 m/s). Radar technology does not depend on temperature, pressure, vapor and dust and provides the ability of measuring up to 100 m.
The basis of the radar measurement is the determination of the time from the radiation of the signal to the reception of the reflected echo. The measured time is used to calculate the distance.
Radar technology provides solutions for changeable conditions that the other technologies can not cope with. The distinctive advantage of radar technology is a signal processing technology - Process Intelligence - an echo processing technique that automatically brings out and puts down "false" echoes to improve measurement accuracy. The technology is developed by Siemens engineers who used the experience of a million applications in one instrument.
Siemens produces a variety of configurations to meet all the unique needs of your application:
SITRANS LR560 for continuous level monitoring in dusty containers
SITRANS LR460 in conditions of high temperature, dustiness
SITRANS LR250 for measuring in storage tanks in conditions of high pressure and temperature, chemicals, non-permanent dielectric properties, thanks to the new encapsulated antenna
SITRANS LR260 for measuring the level of bulk materials under conditions of high dust and high temperature
SITRANS Probe LR with compact connection to the process and low frequency is better used for measuring volume and level of liquid materials in simple working tanks.
SITRANS LR200 for measuring the liquid level in simple working tanks and sedimentation tanks, as well as in conditions of adhesion of the material or condensation
SITRANS LR400 for continuous monitoring of large levels of liquids and bulk materials
SITRANS LR300 for measuring liquid and slurry levels in extreme conditions and in case of explosion hazard.
Siemens radar transmitters are manufactured in accordance with the requirements of the standard Quality ISO 9001: 2008 and the ISO environmental standard 14001: 2004.
Both at a large oil depot and in small bunkers Siemens radar transmitters can Work both offline or connected to the network.
