- Adjustable measuring ranges
- Switchable output signals
- Switchable characteristic curve (linear or square-rooted)
- Zero-point reset button
- Full scale value adjustable by the customer
- Attractive price-performance ratio
- Application possible in overpressure and vacuum ranges
- Easy installation. Mounting bracket for wall or ceiling mounting integrated into the housing
