PT-500C | Submersible Pressure Level Transmitters For Clean and Dirty Liquids
The PT-500 is a rugged submersible pressure transmitter designed for tank liquid level measurement, water and wastewater applications, and well depth measurement.
Use Removable cage fitting and 1-1/2” tri-clover fitting for dirty liquids. Use nose cone fitting for clean liquids. Choose button below.

PRODUCT INFO
Monitor liquid levels with an Pressure Sensor and a ControlByWeb® module. Receive text messages or email alerts when a user-specified level is reached. Log and plot the level history, and more.
How do Pressure Sensors 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
The PT-500 is ideal for clean liquids and can be fitted with a protective cage, making it well suited to handle dirty liquids.
- Stainless Steel Enclosure
The PT-500 Series are enclosed in stainless steel, making them compatible with most chemicals.
Sensor Output
- Modbus RS-485
Easily configure sensor data using the X-404 Modbus Master Controller. No voltage scaling required! - 4-20mA
For exisiting systems that require 4-20mA, connect the sensor to one of our compatible devices (X-418, X-420, X-22s).
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.
Control Pumps Using Pressure Transducer Data
- Control Options
In addition to simple remote monitoring, 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.
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.
