Siemens Process Instrumentation is seeking a distance/filling level sensor solution which is battery powered and explosion protected (ATEX Zone 1). The aim is to address the emerging markets based on Industrial Internet of Things (IIoT) in the process automation. This involves monitoring and optimizing of inventory in the process automation. Here, the distance to dry dusty solids and liquids has to be measured.
The IoT based approach to provide digital services, based on sensor data is already proven in various established markets. In the process automation field, this concept for new business models just started. We see a high potential with a strong growing market in this business field and identified a large amount of use cases with various requirements for IIoT based level sensors.
Key success Criteria
Non-contact distance or level sensor, e.g. ultrasound, radar, laser, lidar, to measure dry dusty solids (sand, stone, cement, grain) and liquids (water, wavy surfaces, foam) with the following properties:
Distance/level measurement from 0 … 5m, better 0 … 10m
Accuracy < 5cm, better <1cm
Measurement rate: 1 measurement each 10min
Data transmission rate: 1/day
Battery powered. Battery lifetime > 5 years, with one external trigger event per month
Cost < 120 EUR
Operation temperature -20ºC .. 60ºC, better -20ºC .. 80ºC
IP67 or better
Explosion protection (ATEX Zone 1)
The external trigger to force measurement and data transmission to 1/min for a specified time, e.g. 1 hour
Data transmission: wireless 4G/5G, GSM. Optional additional WiFi/BT communication for commissioning and maintenance
Optional: separation of sensor and communication
Optional: Additional sensors: temperature, vibration, position (GPS)
Siemens Process Instrumentation (PD PA PI) is open to all solutions that meet the key success criteria.
Approaches not of Interest
A solution not meeting criteria 1) to 5)
