Integrated ultrasonic level meter Overview
Ultrasonic level meter ultrasonic pulse sent by the transducer (probe), encountered the measured medium surface is reflected back part of the reflected echo the same transducer accepted and converted into electrical signals. An ultrasonic pulse to the speed of sound, the desired time interval and the transducer to the measured surface of the medium is proportional to the distance from the emission to the reception of the ultrasonic pulse. Features
the use of state-of-the-art microprocessor and unique EchoDiscovery echo processing technology can be applied to a variety of complex conditions
the false echoes learning "feature allows multiple false echoes working conditions, the right to confirm the true echo to obtain accurate measurements
transducer (probe) built-in temperature sensor, temperature compensation of the measured values can be realized
transducer best acoustic match patented technology, strong radiation, transmit power, signal strength, in order to achieve accurate measurements
The main technical indicators Type RJSL651 RJSL652 Applications Level measurement in various industrial fields Maximum range 0.25 ~ 4m 0.4 ~ 8m Process connection G1 ½ A G2A Measurement accuracy ± 0.5% Weight 3Kg Transducer housing material PTFE, PU / PC Ultrasonic frequency 55KHz Hair angle 5.5o Process temperature -40 ~ +70 °C Process pressure -0.02 ~ 0.1MPa Relative humidity <95% Integration time 0 ~ 40S Output signal 4 ~ 20mA/HART Working power Two-wire 24VDC, four-wire 24VDC/220VAC Shell protection Aluminum / IP67 / Intrinsically Safe + flameproof Protection class Intrinsically safe: ExiaIIBT6
