ict 1000 Smart Dual Mode Hydrostatic Level Transmitter

PSM Instrumentation

Digital and Analogue Transmitters

PSM has drawn upon 30 years of global marine industry application experience to develop a smart dual mode Modbus and analogue liquid level transmitter that offers you the highest possible standards in terms of performance, versatility, functionality and reliability.

The ict 1000 hydrostatic level transmitter’s pioneering capacitive measurement cell is manufactured in robust and durable ceramic. Our careful design of the sensor means the diaphragm is fully supported and protected against overload and shock pressure conditions.

Key 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
  • Robust construction gives reliable operation and low maintenance costs

Self Powered Contents Gauge

AJD Instruments

The AJD Self Powered Contents Gauges require no external power to provide a continuous readout of Tank Contents,in Engineering Units, in Vented Vessels. It is simple to install with both internal and external sensor mounting options.

The Instrument may be fitted with up to 30  Metres of Capillary with 3 Metres being standard. A detachable capillary option is available where it the capillary is to pass through a wall on under a roadway etc.

The instrument monitors hydrostatic pressure and is therefore calibrated at the SG of the stored liquid. Calibration is at a stated Temperature up to 100° C.

The Indicator is All Stainless Steel and is available in 100, 160 and 250mm case size.

A variety of wetted parts and connections are available for compatibility with the stored products.

Note: Options for Alarm Switches or Analogue Re-transmission are available.

Marine For the marine market we have a range of self-powered tank contents gauges, which have been designed for many onboard applications and against liquids such as Heavy Fuel Oil, Diesel and Lube Oils to potable, bilge and seawater. The dial indicators are of Stainless Steel construction and are weatherproof, as with all marine-type gauges they are fully overload protected. Calibration can be completed in any unit of mass, volume or height with dual scales an option. We have in place Bureau Veritas certification for the Internal Sensor type [I.M.] and the Bulkhead / Gland system which, if required, allows the indicator to be mounted in a separate compartment away from the tank. The bulkhead coupling only requires a 38mm diameter hole in the bulkhead and then using the sealing washer the coupling can be fitted along the capillary of a bulkhead gland once the capillary has been passed through. At the time of manufacture, the gauge capillary will be fitted with bulkhead glands at pre-determined points. Once the capillary has been passed through and the coupling and gland have been aligned, it can be secured in place using the nut and compression washers of the bulkhead coupling. The bulkhead will then retain its gas and watertight integrity. If required this system can be fitted into several bulkheads.


220 Level Monitor

Contrec Instruments

The Model 220 Level Monitor accepts a 4-20mA signal from a wide range of level sensors, including pressure transmitters, ultrasonic sensors or capacitance probes, and displays both level and tank contents on a large LCD display.

Solid state relay outputs provide up to four level alarms and a 25 point non-linearity correction table allows the instrument to be programmed to fit most tanks.The Level Monitor is powered entirely from the 4-20mA current loop and, therefore, requires no external power or batteries.

The instrument is fully programmable with setup parameters such as span, offset, alarm levels, etc, stored in a non-volatile memory which will retain all data for more than 10 years without power.

The Model 220 is housed in an attractive IP67 (Nema 4X) polycarbonate enclosure which is completely watertight.A wall mounting bracket is supplied as standard, while a 2″ pipe mounting bracket is available as an option.Alternatively, the Model 220 can be supplied as a panel mount instrument.
