HX19R series: Ultrasonic Distance Receiver (2.4Ghz COM RFID)


  • Temperature Compensated
  • Calibrated to 10 meters
  • Industrial Protection IP67
  • Ultrasonic Vibrating Surface (Anodized Aluminum)


The hx19r18-ip67-tcal, calibrated and temperature compensated device. Maximum precision is 1 mm, at absolute accuracy of 5mm over the entire range. Hx19r18-ip67-tcal,times the flight of the longitudinal ultrasonic wave, and decodes the identity of the incoming RFID and USID (ultrasonic identification). The distance to the RFID (ultrasonic) transmitter is  measured with a resolution of 1mm. And the result from each time of flight acquisition cycle is either stored in ring buffers for delayed polling, or broadcasted as it comes over 2.4GHZ RF channel. Indefinite number of receivers can be used to monitor the position of transmitters. I.e. the more receivers monitoring the more accurate is the position. This device comes in two versions one with a pigtail lead for a power supply, and the other with internal battery.

The graph shown on the left represents the beam pattern of the hx19r18, the blue line marks the 6db receive sensitivity drop limit.
