TCM Temperature sensors for secondary barrier and double hull

These sensors are specially designed for the monitoring of gas leaks in the space of secondary barrier and double hull of LNG tanks. With a temperature range from -200°C to + 200°C of the sensitive element (as well as its cable) the measurement accuracys is class 1 or 2, UTE 46202 standard. According to the users requirements, CMR can provide these sensors in several versions : PT100 simplex or duplex, with an individual connection box or with marked wires.

We are also capable to make a special version for extreme situation with a MIC (Mineral Insulated Cable) which allows to use these sensors in immersed locations. The newest reference in China is the supplying of these sensors on five 147,200 m3 LNG ships scheduled to be delivered in 2007. Built under latest technology, the transportation of LNG will be done under 162°C.

CMR a recognised supplier of temperature sensors and Power Plants (Nuclear) and other industrial applications, including hazardous atmospheres.

Expert advice of the inventor of the "precabling systems" concept (first patent in 1972).

Applications

- Connection of sensors used for monitoring diesel and gas engines
- Transmission of measuring signals
- Transmission of power supply to ignition coils for gas engines.

The MS modules range is completed by the MS4S, used for the acquisition of an analog signal and, after processing, monitoring this signal with regard to 4 adjustable thresholds associated to 4 relays with inverting contact.
This module also supplies a 4-20 mA signal, insulated for duplication of the input on an indicator, or for a possible PLC input.


MS modules were developed to withstand severe industrial applications, and perform the following functions :
Signal conditioning; Adjustable threshold monitoring; Affecting
a binary control function; Power supply; and Insulation.

MS modules are designed to perform discrete functions but link specifically to complete a larger, more sophisticated monitoring and control system.
Using single-channel modules the installation may be configured into custom systems likely that can be installed on DIN rail nearest to the equipment to be monitored.
The plug type terminal blocks ensure very rapid wiring and installation/removal.

- The expertise of a specialist of the instrumentation and treatment of low-level signals.
- Total mastery of the measuring channel by a recognised specialist.
- Guarantee of quality and reliability backed up by the ISO 9001 certification.

Complete range of applications: from single channel monitoring module to control-command systems, approved, for the most part, by the principal classification societies.
- The possibily to develop products which suit specific applications, including complex requirements.
- The assurance of logistics and service available wold wide thanks to an international presence.

The complete Monitoring, alarm and control system.
The heart of this system is the CMR 900.

- CMR 900 combines economy and security, compatibility enhanced with adaptability.
- CMR 900 provides most often the functions requested for marine applications.
- CMR 900 is designed specifically for small to mid-sized applications.
- Refrences on more than 50 vessels using the CMR 900

The SCP/SCB is a programmable acquisition system used to scan analog and binary imputs. The measured values and the sensor conditions are transmitted across the CAN Bus network using the CANopen protocol.

This system is used in conjunction with a CANopen master unit such as the CMR CLARINE, to provide a complete engine monitoring solution.
Utilising the SCP drastically reduces cabling due to the close proximity of the pipe and electronic module to the engine sensors.
The high reliability of the CAN Bus is justified by a proven track record in many industrial applications.
The CANopen protocol is already the industry standard and is highly recommended by the Merchant Navy, among others, for its high levels of reliability and flexibility.
