SNT Sensortechnik AG has released the UPR1503 ultrasonic distance sensors, based on the UPR series. They are available from SICK .
The sensors are a compact M18 size with a large measuring range and 90° (radial) Sonarange transducer for confined mounting conditions. The sensors have an extended measuring range of 1500mm with analogue output in V or mA. Applications include distance and level measurement.
The full scale (10V or 20mA) can be set with a multiturn potentiometer between 500mm and 1500mm. The sensors are IP67 100% waterproof.
