The PX709GW Series submersible level/depth transducers and transmitters are designed to make precision level or depth measurements in fresh water or liquids compatible with 316 SS reliably for years in harsh industrial environments. They are also ideal for environmental monitoring of job sites and field locations. their 25mm (1.0") dia. fits most down hole well applications.

The PX709GW series has the proven Omega MicroMachined silicon technology as its core sensor. The Piezoresistive technology uses precision solid state strain gauges molecularly embedded into a highly stable silicon wafer. The silicon is mounted in a sealed chamber and protected from the environmental fluids by a pressure sensitive stainless steel diaphragm. A very small volume of silicone oil transfers the pressure from the diaphragm to the silicon sensor. The cable is molded onto the case using a unique high pressure, high temperature system to assure the best possible quality seal for long life and durability. This technology produces a very rugged, high stability sensor with exceptional accuracy, minimal thermal effects and long term reliability.

Weatherproof enclosures are also available to easily terminate your transmitter at your control location. The enclosures have fittings to hold the desiccant and locations to make all your connections. They are also available with Lightning/Surge protection to protect your wiring and instruments. Protected models are available for 4-20 mA outputs or the amplified 0-5 or 0-10 Vdc outputs.

3 x Pressure Reference Types: Gauge pressure (vented through the cable), Sealed gauge pressure, Absolute pressure

4 x Electrical Outputs: mV/V, 0-5Vdc, 0-10Vdc, or 4-20 mA
