Non-submersible pressure sensor / hydro-static bubbler
The WaterLOG® H-3531 FlashLite™ is a NIST traceable pressure sensor. The sensor directly measures dry gas with accuracy better than 0.02% FSO. Combining high accuracy and low cost, the H-3531 FlashLite™ is the clear choice.
Features
- Directly measure dry air gas pressure
- Pressure accuracy is 0.02% full scale
- Accuracy over temperature range exceeds ±0.02ft. (6mm) of water
- Built-in temperature compensation
- Operating temperature range -40 to +60C
- Easy to use Simple RS-232 Menu Interface
- SDI-12 output provides measurement data in engineering units such as feet or meters
- Standard mode: Quadrature, 0-5V, and RS-232
- Industrial mode: 4-20mA and RS-485 Interface for Modbus/H-355 Gas Purge System Control
- Easy to use with H-355 Gas Purge System
- Compatible with RS-232 Data Logger
- Enclosure is nonconductive and corrosion proof
- Low current operation (Less than 1mA standby)
- Extended SDI-12 command for setting the Stage to the current water elevation or pressure
- Programmable continuous update outputs Measure Rate mode
