INW PT2X Water Level Sensor

The INW PT2X is a water level sensor based on the pressure principle. The sensor is temperature compensated and available in ranges from 0..0,7 up to 0..210 mH2O. Cabled version and version with internal data logger available. Small diameter of 1,9 cm, thus suitable for various wells.

Great almost anywhere you need to measure level and temperature - whether it be in a lake, in a tank, or in a well.

Features sensor

• Pressure, temperature, time

• Absolute, gauge, or sealed gauge

• Thermally compensated - great where water temperatures vary, such as in streams or in industrial tank applications

• ± 0.06% FSO typical accuracy

• Low power - 2 internal AA batteries

• External power options (12 VDC) with AA's acting as backup

• 316 SS, Viton®, Teflon® construction (titanium optional)

• Small diameter - 0.75" (1.9 cm)

• Modbus® and SDI-12 interface for greater flexibility

Datalogger

• 130,000 record, 260,000 record, and 520,000 record versions

• Non-volatile memory - data will not be lost in the event of a power failure

• Flexible, multi-phase logging sequences - save sequences to disk to reuse in the future

• Pause logging feature - temporarily pause the logging while repositioning or transporting sensor

• Delayed start feature - state a specific future start time, making it easy to set several sensors to start at the same time.

Cabling and Networking

• Wireless connectivity - radios and/or cellular

• RS485 network - allows several sensors to be networked together and allows much longer cable leads than does RS232

• Field serviceable connectors - easily remove the connector, route cable through well seals, walls, or conduit, and then replace connector

• Available cable less or with a variety of cable options - polyethylene, polyurethane, or FEP Teflon®

• The PT2X can be connected to the OMC-045-III data logger.

Software - Free, easy-to-use

• Real time viewing

• Easy export to spreadsheets and databases

• Barometric compensation utility for use with absolute sensors

• Ability to update sensor via firmware while in the field - great for future updates or custom development
