The pressure transducer DMU2/A registers the over-pressure, under-pressure and the pressure difference at the two pressure outlets and converts the measured value into a linear output signal 0-10 V respectively 4-20 mA um. 8 different scales can be selected, which can be switched freely using the innovative DIP switch technology. The output attenuation of the pressure transducer (0 sec / 1 sec / 5 sec / 10 sec) can also be selected using a DIP switch. For a manual calibration of the zero point the pressure transducer performs a zero point balance in situ at the push of a button. If required the pressure transducer can be finely calibrated in situ using an SPAN controller. The aluminium housing ensures an extremely high mechanical robustness and has an EMS thread for the easy and safe EMC conform wiring.

Manual zero-point adjustment: | The zero point adjustment is started by pressing the button on the circuit board (push 10 s until LED stops flashing or by the display version the countdown 10-0 is completed). Before, a continuous operation of at least 1 hour must be sure, the offset must be in the middle position and the pressure inputs P+ and P- must be an obvious offense to the environment. The successful calibration will be signalized by 5 sec durable lightning of the LED. |
