Explosion Proof Flexible SS and PVDF Stem Magnetostrictive Level Sensors

MPXI-F

Explosion Proof Installation For Your Tallest Tanks

The Explosion-Proof MPXI-F features a flexible proprietary-PVDF or 316L SS braided-tubing stem for easy installation in tall tanks.

The MPXI-F Explosion Proof Flexible SS and PVDF Stem Magnetostrictive Level Sensor is easy to install, every time. World-wide, explosion-proof/flame-proof installation? Easy. Flexible stem for crane-less installation in tanks up to 50 feet tall? Easy. Optional temperature sensors and high-level switch for extra protection? Easy.

MULTIPLE OUTPUT CHOICES

Because the MPXI-F carries explosion-proof installation certifications, you can run Modbus network lines right up to each sensor without worrying about IS barriers. Or choose loop-powered 4-20 mA sensors for easy 2- or 4-wire hook up.

TANK CLOUD COMPATIBLE

The MPXI-F liquid level sensor is a Tank Cloud client sensor, able to communicate via the Internet with the addition of an LOE server sensor (Modbus output only) or an RST-5003 module (Modbus or 4-20 mA output).

QUICK START-UP

With its low-power-consumption design, and a start-up time of under five seconds, the MPXI-F level sensor makes battery power for remote installations easy.

FLEXIBLE

The MPXI-F is designed for easy installation. The both the proprietary-PVDF stem and the 316 SS flexible tubing stem coil for compact shipping and on-site transportation. And with the stem weight attached, they uncoil easily into your tank, so you no longer need a flat bed truck and an 60-foot crane to install a 30-foot probe in a 30-foot tank.

OPTIONS

The PVDF MPXI-F level sensor has an optional high-level switch (located 23.5" below probe zero reference) that is wired to independent of sensor operation. So even in the event of probe failure, you'll still get the high level alert. And both stem types allow for up to seven temperature sensors evenly spaced along the stem, providing real-time temperature output from inside your tanks.
