The pressure transmitters of the 4LD series use the chip-in-oil technology developed by KELLER, uniting a pressure measuring cell, digital temperature compensation and signal processing in a compact housing made of stainless steel or Hastelloy. The transmitters are extremely resistant to environmental influences and delivery highly accurate measurement results as a digital output signal. The I2C interface and the low supply voltages make it easy to integrate in microcontroller-based systems. The extremely low power consumption is ideal for battery-operated devices. The D line is perfect for IoT solutions.

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.
