Wireless differential pressure sensor (DLPa)
Article number
DLPa
Description
DLPa
The Wireless Value DLPa measures the pressure difference between two points as a relative value. The differential pressure across the two ports is measured using the hot-wire principle. Thanks to its high sensitivity, this sensor is ideal for use in laboratory environments such as cleanrooms and in biological research.- Memory to store 10,000 measurements
- Adjustable measurement interval
- Suitable for wall mounting
- Existing system can easily be expanded with additional sensors
- Battery replaceable by user
- Unique network ID to avoid interference with other wireless systems
