||The PX Universal is a wireless catch monitoring sensor of which three versions are available: PX Universal, PX Universal Depth/Temperature (D/T) and PX Universal Catch/Temperature (C/T). The version is defined by the type of sensor lid, which in turn determines which parameters are measured. All three versions can measure the pitch, roll and height of the net, in addition to reporting the battery status of the sensor, with typical applications on trawl or purse seine. The most common version is the PX Universal D/T, which also measures temperature and the depth and sink rate of the net, with applications on seine nets. The PX Universal C/T is distinguished by being able to measure catch in addition to temperature. For operation, the sensor requires a suitable Kongsberg PI or SR Series receiver, one or more hydrophones and a computer running the Simrad TV80 or Simrad PI50 programs. The sensor can measure two parameters, with an additional license required to measure an additional three (for a total of five parameters simultaneously). The standard sensor is depth rated to 1400 metres in an operating temperature range of 0 to 50 degC. The sensor measures at a depth measurement accuracy of 0.5%, roll and pitch angle measurement of +/- 90 degrees (+/- 2 degrees accuracy), spread measurement range of 0 to 600 metres, and battery status measurement of 0 to 100% (+/- 1% accuracy). The maximum communication distance between the sensor and receiver is 2500 m.
