Burkert Element Neutrino 8202 and 8222 analytical transmitters

Burkert has launched the Neutrino analytical transmitters; the 8202 (for pH or redox potential) and 8222 (for conductivity). They are designed for operation with different sensor types, offering adaption across a range of applications where measurement of pH, ORP or conductivity is required.

The transmitters are part of the Element system, which links clean line valves, sensors, positioners and valve actuators in an intelligent architecture to solve total control loop processes. The system has unlimited modularity and saves processing time by offering total control solutions for media from slurries to steam, and from deionised water to hydrochloric acid. The system’s devices are engineered for long service life in wet, aggressive and arduous environments.

The transmitters feature a variable electrical connection for pH electrodes, making it possible to use most pH electrodes with a 12 mm diameter and an S7 connection. As a result, users have greater flexibility, as a single standard transmitter can be used for all applications within the system.

Moreover, the option of selecting from three cell constants (0.01, 0.1 or 1) for measuring conductivity ensures versatility when exchanging sensors, as well as adaptability to the required task. This results in reduced inventory costs and administrative requirements, together with improved product life cycle.

Also adding to the functionality and accuracy of the transmitters is an integrated pt1000 sensor, which provides internal temperature compensation. The temperature value provided by the sensor is delivered as a second process variable in the transmitter, and can also be output as a 4-20 mA signal. This eliminates the requirement and costs for a separate temperature sensor.

Both transmitters are simple to use; they are supplied with a key for selecting the required measuring mode, and offer measuring range selection with 16-position multipoint switch and allocated ranges, together with the facility for one-point and two-point calibration for pH and ORP. Monitoring for calibration processes, device status, warning and alarms, is provided via an integrated LED status display.
