The ANNOVEX-Evaluator is an universal evaluator for the sensors/transmitters of the ANNOVEX/MONIMET-system. All available device types can be connected. The Evaluator automatically recognizes the sensor/transmitter and takes over the display, the evaluation and operation of the sensor/transmitter.
Simple and secured operability, robustness, low weight and small dimensions distinguish the cost efficient, stationary ANNOVEX-Evaluator.
These devices conform to the explosion protection rating of intrinsic safety „i“, catagory I M1 Ex ia I Ma. This means that this devices can be used in the zone M1 of underground mines, even when unpermitted high concentrations of the methane gas are prevailing.
This certification conforms to the ATEX directive 94/9/EC for devices and protective systems permitted for use in areas endangered by explosions.
The ANNOVEX-Evaluator can be extended with an additional limit switch unit that is equipped with relays or optocouplers.
The operation of the device is very simple and the housing need not be opened: The operator places a small magnetic press button unit on the device. As an alternative he can also use a
magnetic pointer. A four digit code protects against unauthorized changing of the set values (can be switched off). A self monitoring microcontroller system not only processes the measurement values precisely, it also carries out the operator specific instructions such as the entry of the code, signal instructions and messages, analog and digital outputs and test functions etc. A four digit back lit graphic display shows the measured values in 12 mm high digits.
The ANNOVEX-Evaluator is protected by an antistatic plastic housing (impact strength 7 Joule). The sensor is to be connected by means of a plug-in connector. Cable entries or a plug-in connector for the electrical connection are attached on the lower side of the housing.
Holes on the back of the device permit a rigid mounting. In addition the ANNOVEX-Evaluator can be equipped with the audio visual alarm unit AVS 3 for giving alarms in the monitored area.
One or more audiovisual alarm devices Type AVS 4 can be connected to an ANNOVEX-Evaluator for giving an extended alarm signal on site.
All ANNOVEX/MONIMET devices can be fed by the uninterruptible power supply device Type USV 4, which also has an ATEXcertification.
