Submersible Transmitter Combining Pressure & Temperature Measurement.

Description

STS is pleased to announce the NEW ATM/N/T precision Pressure & Temperature depth and level transmitter which is fully submersible for monitoring ground or surface water, waste water or tank level measurement. The ATM/N/T features a rugged modular design in 316L SS or titanium. Full scale ranges from 40” WC through 360 psi are available with a proof pressure of typically greater than 3 x FS and a static accuracy of typically 0.1%. Operating process temperatures from 25 to 125°F are acceptable. The supply voltage from 15 to 30 VDC provides a range of dual output signals for pressure and temperature such as 4 to 20 mA, 0 to 20 mA, 0 to 5 VDC or 0 to 10 VDC for the full scale. The ATM/N/T can be built with either Polyurethane, Polyethylene or FEP cable up to 5,000 feet. Many features are available including a field replaceable cable version.
