The PX709GW Series submersiblelevel/depth transducers and transmitters are designedto make precision level or depthmeasurements in fresh water orliquids compatible with 316 SSreliably for years in harsh industrialenvironments. They are also ideal for environmental monitoring of job sites and field locations.The PX709GW series has the proven trodeksmicromachined silicon technology asits core sensor. The Piezoresistivetechnology uses precision solid statestrain gages molecularly embeddedinto a highly stable silicon wafer.The silicon is mounted in a sealedchamber and protected from theenvironmental fluids by a pressuresensitive stainless steel diaphragm.A very small volume of siliconeoil transfers the pressure from thediaphragm to the silicon sensor.The cable is molded onto the caseusing a unique high pressure, hightemperature system to assure thebest possible quality seal for longlife and durability. This technologyproduces a very rugged, highstability sensor with exceptionalaccuracy, minimal thermal effectsand 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 to 5 or 0-10 Vdc outputs.

trodeks has developed a Modular Manufacturing System so we can deliver almost any combination of pressure type, output, pressure range and cable length with or without internal lightning/surge protection in 1 Week!

3 Pressure Types: Gage pressure (vented through the cable), Sealed gage pressure, Absolute pressure

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

Pressure Ranges: from 10 inH2O to 1000 psi

The Standard cable length is 10 ft and optional lengths are available up to 300 ft.
