The Series 46X sensors allow for highly accurate water depth measurements to be taken with a capacitive pressure cell suitable for ranges from 0-300mm up to 30m. PR46X sensors include a reference tube integrated in the PE cable and connects the referential chamber of the sensor with the current ambient pressure. Sensors can provide voltage or mA outputs, along with an RS485 output, which also allow the analogue output to be adjusted and read pressure and temperature readings to be collected via a serial output.
The Series 46X combines the ceramic measuring cell for low pressure ranges with the μP-electronics of the digital Series 30 pressure transmitters. The level sensors of the 46X series combine a ceramic measuring cell for very low measuring ranges on the mBar scale with microprocessor electronics for compensating for temperature dependence and non-linearity. This produces a high accuracy depth sensor for ranges from 0-3 metres WG down to 0-300mm WG In addition to the digital RS485 interface, the sensors also have a rangeable analog output. The signal values of the pressure and temperature sensors are determined by a polynomial compensation. The values can be shown and stored on a PC and can be reprogrammed. The Series 46X sensors include a reference tube integrated in the PE cable and connects the referential chamber of the sensor with the ambient pressure. Allowing readings to automatically adjust for ambient pressure. The PA46X series is no longer available.
