The 23SY-H2 series is characterised by its low embrittlement rate due to the increased nickel content in the stainless steel. Thanks to a gold-plated diaphragm, H2 diffusion is also reduced to a minimum. The pressure transmitters are compensated over the entire temperature range and offer excellent long-term stability. The 23SY-H2 series products are a reliable solution with long service life, high accuracy and safety to meet all hydrogen requirements.

The pressure transmitters of the 21Y series have no internal seal and a high insulation voltage of 300 VDC, and are extremely resistant to environmental influences. The sophisticated compensation circuit makes it possible to specify a narrow total error band. A wide range of pressure connections and electrical connections are available to choose from.

In the high-precision level sensors of the 36XW series, the temperature dependence and nonlinearity are precisely compensated for in the microcontroller by means of a mathematical model. In addition to the RS485 interface, the measurement results can also be output via the integrated D/A converter as a rangeable analog signal. Extended lightning protection is also available as an option.

The pressure transmitters of the 33X 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.
