ProSight Submersible Liquid Level & Temperature Transmitter
ProSight Submersible Liquid Level & Temperature Transmitter is a submersible liquid level and temperature transmitter designed for simultaneous monitoring of liquid depth and temperature in industrial and process applications. It is primarily used in water treatment, food processing, crude oil, and liquid storage or monitoring systems. Key features include an oil-filled diffusion silicon pressure sensor, integrated PT100 temperature sensor, dual level-and-temperature outputs, IP68 protection, high overload capacity, and optional Modbus-485 communication.
The ProSight Submersible Liquid Level & Temperature Transmitter is a combined liquid level and temperature measurement device designed for applications where both parameters need to be monitored from a single immersion point.
The transmitter incorporates an advanced oil-filled diffusion silicon pressure sensing core for liquid level measurement and a PT100 temperature sensor for measuring liquid temperature. By combining both sensing elements into one compact submersible unit, the ProSight Submersible Liquid Level & Temperature Transmitter can save installation space and simplify system design compared with installing separate level and temperature sensors.
The device is designed for throw-in installation, meaning it is immersed directly into the liquid being measured. Its IP68 enclosure protection makes it suitable for continuous submerged applications when properly installed and operated within its specified limits.
The ProSight Submersible Liquid Level & Temperature Transmitter can provide 4–20 mA, 0.5–4.5 V, or RS485 output options, depending on the selected configuration. The intelligent version supports Modbus-485 communication, allowing measurement data to be integrated into PLC, SCADA, HMI, data acquisition, and industrial monitoring systems.
How Does It Work?
- Submersible installation — The transmitter is lowered directly into the liquid using its throw-in installation design.
- Liquid level measurement — The oil-filled diffusion silicon pressure sensor detects hydrostatic pressure created by the liquid column above the sensor.
- Level calculation — The measured hydrostatic pressure is correlated with liquid depth, providing continuous level information.
- Temperature measurement — The integrated PT100 sensor directly measures the temperature of the surrounding liquid.
- Signal conditioning — A specialized signal-conditioning circuit processes the pressure and temperature signals and converts them into standardized outputs.
- Data transmission — The resulting level and temperature information can be transmitted through analog outputs or RS485 communication for monitoring and control.
- Automation integration — The transmitter can provide data to connected control systems for level monitoring, temperature management, alarms, pump control, and process automation.
