How do Pressure Transducers Work
Submersible pressure transducers work just like other pressure transducers, except they’re inside a water-tight housing, and they read in feet or inches of liquid (adjusted to specific gravity) rather than PSI.When a pressure sensor is installed near the bottom of a tank. It uses an internal diaphragm which flexes with changes in pressure. This flexing sends an electrical signal to the attached ControlByWeb module which automatically calculates the depth. This data can then be viewed using a standard web browser over an IP network.

Liquid Types
Ideal for clean liquids and can be fitted with a protective cage - suited to handle dirty liquids.

Stainless Steel Enclosure
The PT-500 Series are enclosed in stainless steel, making them compatible with most chemicals.

Control Pumps Using Submersible Pressure Transducer Data

Control Options

ControlByWeb modules are fully programmable and provide custom control capabilities as well. For example, you can connect a pump to a relay on a ControlByWeb module and remotely run the pump manually, or configure the pump to automatically run if the level gets too low.

Recommended Installation
Tank Vents – Submersible Sensor

Thread the PT-500 Pressure Transducer through vents in a tank.

Tank must be vented to atmosphere.		 Head Pressure

Connect the pressure transducer to the head pressure to monitor tank levels.

Tank must be vented to atmosphere.
Level Monitoring in Hazardous Environments

Warning: Use of these products to monitor tank levels of potentially explosive liquids or substances (such as gasoline), requires strict adherence to local safety laws and regulations. ControlByWeb modules (such as the X-404, X-420, etc) are NOT designed to be intrinsically safe and must be installed with both physical and electrical safety barriers. Installation should only be performed by qualified individuals and companies who understand the safety requirements. Please refer to sensor installation manuals and consult local safety regulations for more information.

Applications

The versatility and reliability of the PT-500 makes it a great multi-purpose level sensor. It excels in water and hydrocarbon-based liquids where the density of the liquid is consistent.
Here are typical applications where you’ll find our PT-500 submersible pressure transducer:
• Lift Stations • Retainer Ponds • Well Level Monitoring • Process Tanks • Remote Level Monitoring • Chemical Tanks • Water Storage • Oil Storage
