NOW also for use in hazardous areas! RedGuard ® RedGuard® Temperature Monitoring System RedGuard® Temperature Monitoring System Locate risks - fast and precise Plant safety and reliability, accident prevention and process and product quality are today the top themes in industrial plants. In every respect, the processes must assure the ultimate in safety and reliability. Safety measures are top priorities particularly in plants with an increased danger potential, such as for example in the chemicals and pharmaceutical industries, in the area of oil & gas, in power stations, in the fodder industry and of course in mining. Temperature monitoring is a highly charged issue. Overheating, fires and leakages can cause immense damage. The earlier the risk is recognised and can be localised, the higher the chance of preventing damage to people, machinery and the environment. 2 RedGuard® Temperature Monitoring System The patented RedGuard® Temperature Monitoring System offers an easy and safe temperature monitoring solution for hazardous areas too. The RedGuard® system design is simple and consists in principle of a sensor cable with integrated sensors and a processor unit. The processor unit registers and analyses the temperature readings values from up to 250 temperature sensors. Whenever the preset threshold readings are exceeded, the system generates an alarm. Applications and areas of use ■ Monitoring of leakage and fire Operating range: energy tunnels and cable ducts ■ Monitoring of temperature in pipes and containers Operating range: process industry, chemicals, pharmaceuticals, oil and gas ■ Leakage, temperature and fire monitoring Operating range: refilling stations and tank farms for flammable liquids Features of the RedGuard® System ■ Sensor spacing freely selectable (2 m, 4 m, 7 m, 10 m, 20 m) ■ Integrated sensor & control system with universal interfaces ■ Wide measuring temperature range (-55 °C to +125 °C) ■ Short system response time (< 5 seconds) ■ Long-time stability, self-monitoring, maintenance-free ■ Possibility of integrating sensors for other parameters ■ Simple project planning, freely programmable system reaction 3 RedGuard® System Design System design/components ■ Sensor cable (SD/polyurethane or HD/fluoropolymer) ■ Connection Filter Module (CFM) for connecting the input lead (CCA) to the sensor cable or connecting two sensor cable segments ■ Protection Filter Module (PFM) protects sensors against undue voltages ■ Cable Termination Module (CTM) to terminate the sensor cable ■ Processor unit (SSP or SRG) ■ Generic Sensor Interface (GSI) to connect external sensors ■ Relay Control Unit (RCU) for controlling a further 32 relays to localize the alarm System design and connection plan CCA access cable RCU GSI CFM/PFM Sensor cable SD or HD SRG Power Alarm Fault CTM External sensor RS232 RS422 ModBus Relay output (32 + 8) Group alarm (1x) Fault (1x) 4 AC 230/115 V RedGuard® System Design Sensor data in real time The processor unit (SSP/SRG) scans the sensor cable and converts the analog signals into temperature measurement values. The complete system is programmed with the RGCC configuration software. The TMON visualisation software is available for the visual presentation of the temperature profile on PC. Define specific treshold 4 threshold values can be defined for each sensor. A further 4 threshold values are freely settable over the complete length of the sensor cable. The sensor data and operating states are scanned in real time on the interfaces. This allows unusual states to be recognised immediately and forwarded or for the alarm to be triggered. Temperature at sensor position Define treshold Power of hot spot Function Reliable alarm and fault relay output The alarm can be programmed for latching or pulse mode. The relay contacts are controlled by means of the software or by hardware monitoring (watchdog). The yellow light diode is coupled with the fault and the red light diode is coupled with the alarm relay. Storage of the temperature readings All events are stored in a cyclic event logger. The event logger can be scanned through the serial interface. Furthermore, all events and also the sensor readings can be saved to a plug-in flash memory. This can be read by an external computer. It contains enough storage space to collect and file data for months.The system can be operated on its own or in combination with superordinate systems through serial interfaces. Integration of external sensors Additional external sensors can be connected through a sensor interface (GSI). 5 RedGuard® System Components Sensor cable The sensor cable contains the entire electronics for measuring temperature, addressing the sensors and transmitting data to the processor unit. The sensor spacings are selectable: 2, 4, 7, 10 or 20 m. One unit can monitor up to 2000 metres of sensor cable. Design The sensor cable consists of an 8-strand flat cable: 2 as redundant conductors for ground, 2 for supply voltage, 2 for data transmission and 2 for addressing. The flat cable is protected by two additional covers. The inner thermoplastic elastomer jacket serves as a barrier to humidity and the outer polyurethane or fluoropolymer jacket is optimised for mechanical and chemical resistance.

The processor unit controls data communication, stores events and monitors the proper functioning of the system. The temperature sensors in the sensor cable are actuated sequentially, the measurements are read into a ring memory and analysed after every interrogation cycle. Depending on the user configuration of the RedGuard® Software, the control unit can output an alarm on an LED and a relay and/or per data interface. The alarm events are configured by means of four threshold temperature values (min./max. absolute temperature or temperature gradient). These threshold readings can be set for the entire system and for each individual sensor. An algorithm allows configuration of up to 25 reaction patterns.
