ICT 1000 Smart Dual Mode Hydrostatic Level Transmitter

ICT 1000 Level Transmitter by PSM Marine

Digital and Analogue Transmitters

The ICT 1000 Level Transmitter from PSM Marine has been developed with their 30 plus years of global marine industry application experience. This smart dual mode Modbus and analogue liquid level transmitter offers the highest possible standards in terms of performance, versatility, functionality and reliability.

This pioneering capacitive measurement cell has been manufactured in robust and durable ceramic. The careful design of the sensor means the diaphragm is fully supported and protected against overload and shock pressure conditions. The ICT 1000 Smart Dual Mode Hydrostatic Level Transmitter is the perfect liquid level transmitter.

Manufactured from 316 stainless steel and employing a carefully engineered seal assembly in a choice of materials, which draws upon PSM's marine application experience to provide a fully submersible (IP68) the transmitter body construction is capable of withstanding the toughest operating conditions for many years. It's advanced features are not confined to mechanical design. The ICT 1000 also features a powerful onboard micro-controller that precisely monitors the pressure related output of the capacitive cell.  Process temperature is also monitored to provide a fully compensated measurement output.

ICT 1000 Level Transmitter features

  • Designed and constructed specifically for marine applications with all relevant industry body and type application approvals
  • Can operate either as an analogue 4 - 20mA hydrostatic level transmitter or can communicate directly to the host system using the RS485 Modbus protocol
  • Full range of process connections and transmitter mounting options available
  • Compatible with all common marine liquids and cargo applications: seawater, fuel and lubricating oil, bilge water etc.
  • Digital bus and mA analogue outputs available on one transmitter. No remote mounted signal conversion electronics are required
  • Output available as level or volume via a user programmable height vs. volume table
  • Multi-drop Modbus digital mode allows for significant cable savings in multiple-tank installations
  • Wide span with a high measurement accuracy and long term stability
  • Programmable remotely via an RS485 modem and supplied software configuration tool
