Modular Economic Sensors: "Modularity without borders"
Based on the versatile modular features, the ME sensor series can be divided into four segments:
Modular Economic Sensors with full equipment
All versions with full equipment are fitted with 4 to 20 mA 2-wire technology, heterodyned HART communication signal and two configurable limit value contacts and are available for all physical measuring categories. The service and setting of the sensors is carried out by means of a user-friendly display with three keys and integrated 4-digit 7-segment current loop display. The display head on the case body is swivelling around 300° and the display is additionally reversible, for an upside down installation of 180°. The case body including the electrical connection also turnable around 300 °.
Modular economic sensors as transmitter versions
Everywhere in processes where exact measuring values are necessary in the form of simply evaluable analogous sensor signals, but no display is required, the transmitter versions can be used as a cost-optimised measuring instrument. The pure transmitter is also available for all current physical measuring dimensions, generates an output signal of 4... 20 mA, has modular electric connection facilities available and is configurable via HART communication.
Modular economic sensors as switch variants with base equipment
For all common physical measuring categories, switch variants with cheaper basic equipment such as simple locally set-point adjustment, high measurement accuracy, fast response time and easy installation are available for all industrial applications. The current output signal can be connected to a digital input of a SPS. The switch sensors are programmable serial, e.g. via a separately available modem. Nevertheless, the switch point setting can be performed directly at the device by an integrated hall sensor in combination with a separate magnet on site. The switch status is recognizable by a red bright LED. The switch output is realized as open collector and galvanically isolated.
Modular economic sensors with radio transmission as additional equipment
As the fourth option, the ME sensors are also planned with radio ability as an additional equipment. Based on the lithium ion technology, these device types work as an energy selfsufficient system on battery power. For fitting the sensor with radio, depending on the application needs, there are modular additional options such as battery operation with internal aerial for short ranges from up to 50 metres, with external power supply for long operating time or with external aerial connection with stationary aerial in the device with a range up to 300 metres or also with a separated aerial for a range up to 5 km with 500 mW RF power and external.
Thanks to its "modularity without borders", the sensor series ME not only creates fast and effectively transparency with industrial measuring tasks but also the model and prize structure is adapted so that the optimum sensor type can be fast and cost-optimised put together modularly for the corresponding demands of the industrial use. Exactly this represents the benefits of the ME series' modular sensor concept by Müller Industrie-Elektronik.
