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.

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

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

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.

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).

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.

RedGuard® System Components
Processor unit
The measurement values are evaluated in the SSP/SRG processor unit. 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.

RedGuard® System Components
Software
The RGCC (RedGuard® Control Center) software is simply installed on a WINDOWS operating system (2000
and XP). This software offers all functionalities for safely configuring, operating and maintaining the
RedGuard® System:
■ Output of the entire set of a plant’s parameters to a PDF document (reporting)
■ Project-related administration and traceability of all plant data and interventions
■ Sensor calibration: recalibration in the field, assignment of the calibration data to the sensors
■ Easy programming of the threshold readings with the aid of the reaction matrix
■ Configuration of the relay output (logical equations)
■ Administration and interpretation of the event logger (LOG data)
■ Graphic display with zoom and pan functions
Data certification
The history of every log and configuration file is always traceable. Each file has a content-dependent code,
with which the authenticity of the contents can be verified.
External data analysis
Data can be read into a standard table calculation program. This allows, for example, sensor values that
correspond to particular critical operating states in the plant to be registered and presented,.
Project management
Several processor units can be combined for projects.
