The type MCU-32 modular distributed automatic measuring apparatus

 

1Product Description

The type MCU-32 modular distributed automatic measuring apparatus (MDAMA) can be applied to acquire and monitor the data generated by sorts of sensors. The MDAMA is not only able to work independently; it can also work cooperatively with other MDAMAs through networking. With the water proof, lighting protection, and anti-interference abilities, MDAMA can perform its work in a wide-rang natural environment. The main functions of MDAMA   include networked and distributed measurement, single time measurement, time-interval multi-times measurement, continuous measurement, timing measurement, automatic data collection and storage, communication with computers, threshold alert, data management, figures/tables generation, manual-comparison measurement, and etc.

2Product Speciality

   Open Architecture, Modularization, High Resolution, Stable Reliability, anti-EMI, and anti-Interference of Power Frequency.
   
Broad Measurement Range and Monitoring Applications: Voltage, Current, Resistance, Capacitance, Frequency, On-off, Pulse, and etc.

    The modules, such as the measurement module, the main control and communication module, the power module, and the interface module, may be freely combined to suit for individual requirements.

    Improved lightning and electrostatic protection, and transient pulse block function. The high voltage pulse can be blocked by the protection circuit firstly, and then absorbed by the absorber circuit, which may ensure the safety of the built-in modules. Sensor protection function is all provided in MCU-32 MDAMA, thus the surge arrester is not necessary.

     Improved self-checking and malfunction reporting function. The MCU-32 MDAMA can check the operating status of the components automatically everyday. If an error is found, the alerting service will be activated. Moreover, 12 LEDs on the panel of each module also indicate the real-time operating status.

    Supporting diverse data transmission methods, such as RS485, TCP/IP, wireless data transceiver??Tele-transmission, wireless network transmission (GPRS/CDMA).

    Flexible data acquisition modes, such as the automatic measurement and reporting mode, the remote measurement mode, and the local storage mode. With the built-in 4MB disk, the MDAMA can store up to 7000 * 32 data items. The data can be transmitted to the computer through the serial port or copied by a USB flash disk.
