The pressure transmitters of the 23SY-Ei series are designed for elevated requirements in industrial applications. Thanks to its modular concept, this series is highly flexible and makes it possible to realise customer-specific requirements in very little time. The sophisticated compensation circuit makes it possible to specify a narrow total error band. Intrinsically safe – suitable for use in explosive atmospheres.

The pressure transmitters of the 35XHT series are suitable for use in media temperatures up to 150 °C and can therefore be used in bioreactors and autoclaves that have to be sterilised regularly. They use digital compensation with a mathematical model to achieve an accuracy of 0,15 %FS – in the temperature range from 10 to 40 °C, this value even corresponds to the total error band. In addition to the digital RS485 interface, the X-line transmitters have a rangeable, analog current or voltage output. The standard model of the 35XHT series has an Ingold fitting as pressure connection.

The pressure transmitters of the 33X-Ed series use digital compensation with a mathematical model to achieve exceptional accuracy of 0,05 %FS – in the temperature range from 10 to 40 °C, this value even corresponds to the total error band. Additional measurements and selections can optionally be used to achieve a precision (and also, if calibrated in an accredited test laboratory, an accuracy) of 0,01 %FS. In addition to the digital RS485 interface, the X-line transmitters have a rangeable, analog current or voltage output. Pressure-proof housing – suitable for use in explosive atmospheres.

The HPX high-pressure calibrator is a high-precision calibration instrument for pressures between 0 bar and 700 bar. The functional calibrator is supplied in a sturdy carrying case and pressure can be quickly generated manually. It is therefore ideal for use in the field. The pressure is measured by the integrated LEX1 manometer and is both shown on the display and output via the RS485 interface. Additional functions such as zero point resetting, peak and trough pressure value indication and leak measurement make it even easier to take measurements.
