Ultrasonic Sensor, 1.5-50 ft. range, 3″ NPT mounting, PC/PET housing -Kynar Transducer, 4-20 mA output, RS232 programmable with RST-3001 module, 6 ft. cableSpecifications(PDF)
The IRU 2000/3000 series sensors use ultrasonic technology to provide a non-contact method of determining distance or level measurements. This versatility makes the IRU series ideal for a variety of applications. The color, translucency, dielectric constant, specific gravity or viscosity of the target does not affect an ultrasonic sensor. Ultrasonic sensors function extremely well in harsh environments, are reliable, and require little or no maintenance. |

Ultrasonic sensing is very similar to radar. The sensor transmits ultrasonic sound waves. If the sound waves meet a solid or reflective object, such as a liquid, they are reflected back and detected by the sensor. The time of flight is measured, and since the speed of sound is a wellknown variable, the distance to the object can be calculated. Until recently, the many variables in the speed of sound created inaccurate readings. With the advent of microprocessor technology, these variables can now be factored into the equation and eliminated. One such variable is ambient temperature. The IRU series incorporates internal temperature compensation to adjust for changes in ambient temperature. The IRU series also incorporates programmable filtering options to account for other variables, such as waves on a liquid, or tank irregularities. The distance to the object is converted into an analog output signal that is user adjustable. |
