The MONIMET-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 and small dimensions distinguish the cost efficient, stationary MONIMETEvaluator.
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 en-dangered by explosions.
The MONIMET-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 MONIMET-Evaluator is protected against shocks, dust and humidity by a cast metal housing (impact strength 20 Joule) and are to be connected by means of plug-in connectors. The connector for the sensor/transmitter is attached on the lower side of the housing. On the upper side there is the plug-in connector for the electrical connection.
A steel hanger is attached for the suspension of the device. For a rigid mounting, the device can be provided with thread holes on its rear (extra charge).
One or more audiovisual alarm devices Type AVS 4 can be connected to an MONIMET-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 ATEX-certification.
