Series 46XEi Intrinsically Safe Capacitive Pressure Sensor

Quick Overview

The Series 46XEi sensor are suitable for use in Zone 1 and 2 hazardous areas. The sensor allows for highly accurate pressure measurements to be taken with a capacitive pressure cell suitable for ranges from 0-30mBar up to 3Bar. PR46XEi 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 scaleable voltage or mA outputs.

The Series 46XEi 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 nonlinearity. 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. PR46X 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.
