## Применение

- Measurement of differential pressure, gauge pressure and vacuum
- Monitoring of filters, ventilators and heat exchangers
- Pressure monitoring in ventilation ducts, laboratories, production areas and clean rooms

## Особенности

- IIoT-ready and future-proof thanks to analogue and digital signal transmission (Modbus ® ) as well as wireless (LoRaWAN ® )
- Time-saving instrument configuration and display of current measured values on the smartphone via NFC or WIKA app
- No cabling effort for retrofit projects thanks to battery operation and LoRaWAN ®
- Decentralised data node − up to four input signals − reduces cabling effort and installation costs
- Reduction of installation costs due to simple wall or DIN rail mounting in a control cabinet
