Reliable fire and system protection:
Differential current monitor type B with pre-warning function, measuring range from10 mA to 3 A.
Early detection of insulation faults can prevent failure of complete electrical plants. Fault current monitoring by measuring differential current is the ideal method for this application. The monitoring requirement for today’s supply systems get more and more complex. Electronic control of drives, switched power supplies and chargers or fluorescent lamps with electronic ballast units can create DC fault currents in the case of earth faults. Standard differential current monitors do not detect this type of faults.
Type B differential current monitor DOLD varimeter IP5883 detects DC and AC fault currents in grounded voltage systems. The measurement is done by an external current transformer.
Contrary to RCD units, IP5883 does not disconnect the mains immediately but signals the fault. The unit includes an easy to read LED bar indicating the fault current and LEDs for operation, pre-alarm and alarm. The measuring range is 10 mA to 3 A. Additional features: broken wire detection, adjustable pre-alarm and test function. This varimeter offers advanced information for specific and cost effective maintenance BEFORE the plant breaks down. |

The RCMS system consists of one or several RCMS460-D / -L or RCMS490-D / -L residual current evaluators, which are able to detect and evaluate fault, residual and operating currents in earthed power supplies via the associated measuring current transformers. The maximum voltage of the system to be monitored depends on the nominal insulation voltage of the measuring current transformers used in case of busbar systems, or on the cables or conductors that are routed through.
Closed W...AB series measuring current transformers are required to measure AC /DC sensitive residual currents (0...2000 Hz). Six W...AB series measuring current transformers require one AN420 power supply unit. W... (closed), WR... (rectangular) and WS... (split-core) series measuring current transformers are used for alternating and pulsating currents (42...2000 Hz).
The measuring current transformer series can be used in any combination with the measuring channels of the evaluators. Each RCMS460-D / -L and RCMS490-D / -L utilizes 12 measuring channels. Up to 90 RCMS evaluators can be connected via a BMS bus (RS-485 interface with BMS protocol), thereby up to 1080 measuring channels (sub-circuits) can be monitored.
If this product is to be used for personnel, fire or plant protection, the frequency response can be set accordingly. The measured currents can be analyzed for harmonics.

The AC and pulsed DC sensitive residual current monitor RCMA420-D (Type A) from Bender is designed for fault and residual current monitoring in earthed power supply systems (TN and TT systems) where an alarm is to be activated in the event of a fault, but disconnection must be prevented. In addition, the device can be used to monitor the current in single conductors, such as PE conductors, N-PE connections and PE-PAS connections. Due to the use of measuring current transformers, the device is nearly independent of the load current and the nominal voltage of the system.
The response value can be adjusted in the range of 10...500 mA. When the prewarning level is reached (50% to 100% of the response value), an alarm message is generated. This information achieved sufficiently well in advance can avoid unexpected disconnections and costly downtimes.
Typical application fields are: Residual current monitoring in earthed two, three or four conductor systems; construction site equipment; current monitoring of single conductors de-energized under normal conditions; socket-outlet circuits for devices which are operated unattended for a long time and which may not fail; alarm systems; safety devices. |

Centralized monitoring and traceability of the temperatures
New LABGUARD 2 version 3.7 with alarms in real time and function back up!
AES CHEMUNEX presents version 3.7 of system LABGUARD 2. Already adopted by many laboratories in France and abroad, LABGUARD 2 is an acquisition unit and of monitoring of the temperatures (and other parameters like: relative humidity, differential pressure, CO2, O2, contacts dry...). The transmission of the data in real time by radio of the emitters towards the receiver and the computer avoids any wiring and allows a very simple and fast installation as well as a very great flexibility.
The software, conforms CFR21 leaves 11, presents a total traceability: the data base is made safe and the software delivered with file of validation (service IQ, OQ available). The new version of the software integrates the function "back up": the data are recorded in each module and can thus be recovered in the event of stop or of computer breakdown. The data security is maximum. The emitters can be supplied with battery cell and/or sector.
The software is conceived in a modular way, various optional modules make it possible to meet the needs for each user (mapping, reference of alarms, localization of the apparatuses at fault, remote consultation, interfacing software quality...)

The Delphin solution
Delphin explores new ways but from conventional starting points - unlike solutions which rely on artificial intelligence. Delphin products enable the creation of innovative expert systems which provide service technicians with information on the condition of their plant and machinery in the form of observation and warning messages. Clicking on a message gives access to graphs and diagrams which provide detailed information on the condition of the plant or machinery. This then enables any maintenance requirements to be performed.
Fundamentals of the Delphin solution
A basic premise of ProfiSignal CMS is that plant and machinery are always made up of the same types of components, e.g. power units, bearings, shafts, axles, gears etc. This is the case irrespective of whether the plant/machinery in question is a turbine, paper machine, pump, compressor, or any other. Processes tend towards a static operational state. This is signified, for example, by a regular number of rotations, the reaching of an operational temperature, the completion of a particular processing point etc. Components are exposed to the same types of aging factors, e.g. material fatigue, wear and tear, corrosion, deposits, leakages. |

rEscan's technology is the answer to the early detection of cord breaks, corrosion and splice failure.
The rEscan system works through magnetic flux leakage; steel cords are magnetized within the belting then measured for the amount of magnetic flux leakage seen in the belt. The key to this system is twin conditioning heads, which aligns all the magnetic domains thus giving a clean strong signal. The system is comprised of a set of two 'conditioning transducers (permanent magnets), one'sense transducer 'and one Tachometer.
As the belt passes by the transducer a signal is sent directly to a rEscan computer system then all data is reviewed on the belt in the Left, Center and Right orientation. Once the data has been analyzed, the rEscan Technician can accurately tell you where the damage is in your belt down to the closest millimeter in precision. "

| The Splice Monitoring System allows the remote measurement of splice elongation. The SMS monitors all types of splices in fabric conveyor belting by imbedding small targets into the belting at a set distance on either side of each vulcanised splice. No such targets are imbedded for mechanical clips. |

FEATURES
The LMTX is a new system for the monitoring of hook load for telescopic cranes also when mechanical extensions are used. The system is composed by a transmission unit LIM-TX, which is hanged on crane hook, and by a receiver unit LIM-RX positioned in the control panel unit.
The LIM-TX is composed by a strain gauge pin for load detecting and by a micro controlled transmitter to send by radio the data weight to the receiver unit.
The new structure of the shackle hook group does not limit the lifting operations.
The unit LIM-RX has two functions: the show of the data weight through a four digits red display, the load limits control.
If used with mechanical extensions (up to four jibs) the LIM-RX allows, through a push button, to set the numbers of jibs and consequently to control the overload limits by a relay contact and a LED indication.
The device is included in SRD (Short Range Device) classification and uses a frequency band of 868.3 Mhz of free use (without any authorization).
The LIM-TX unit works with a battery rechargeable by the truck lighter and the LIM-RX unit works by a 12..24 voltage battery.
Free maintenance. No interference with the other on board radio devices.
