IOT Based Remote Monitoring & Controlling System

Diesel Level Transmitter - Submersible

This pressure transmitter suitable for hydrostatic depth measurement which continuously outputs digital(RS385) signals simultaneously.

The RS485 interface provides a communication link to digital monitoring systems, such as the Tank Gauging System. The transmitter's parameters, including zero and span, can be adjusted via the Rs485 interface.

This transmitter offers a very high accuracy over a wide temperature range, an excellent repeatability and very long term stability. Large numbers of transmitters can be interconnected in a multi-drop configuration to help cut down on cabling.

The sensor is isolated from the process by a stainless steel diaphragm and a filling liquid. The electronics are located within the hermetically sealed transmitter housing which gives the excellent resistance to shock and vibration.

The electronics is a state-of-the-art signal processing unit fitted with a fast micro-controller allowing the compensation of drift effects due to temperature on the sensor signal, over a wide temperature range with a fast response time.
