The measuring device detects the oxygen level O2 (0...25/100% vol.) in the ambient air. The transmitter converts the measured value into a standardized, digital output signal Modbus RTU. As an option, the measuring device has a backlit, rotatable display and potential-free changeover contact. In the version with a backlit LCD display, the measured values and min/max values are displayed. The switching threshold and hysteresis can be set as required using a bus command. Measured values from other bus users can be shown in the display as special functions. To display measured values from other bus users, these are entered by the bus master in the appropriate registers. The optional changeover contact can also be used for measured values from other bus users. The address, transmission mode/speed, terminating resistor and master/slave function of the bus devices are conveniently configured using innovative DIP switch technology. This means that the devices can be integrated quickly and easily into the system and later parameterized via the master. The bus devices can even be reset to factory settings by the master during operation. The basic functionality of the device is restored in a matter of seconds. This can happen with incorrect parameterizations of e.g. Offset, switching threshold, display modes etc. may be necessary. The housing with innovative hinge locking technology, double PG screw connection, sufficient terminal space and easy-to-connect push-in connection terminals offers maximum installation freedom and speed. The oxygen measuring device is ideal for use in workplaces and medical facilities.
