MPM6861 Microsensorcorp Wireless Pressure Transmitter

MPM6861 is a wireless pressure transmitter with low power consumption and wireless communication function. It can be equipped with various network including NB-IoT/4G. It reports the data according to the set interval and sends alarms to users. Customers can configure the device and inquire for data remotely by Web page. All the upload and download data will be stored into the database automatically for later query.

It is more intuitive, accurate and efficient through PC or mobile terminals access internet to acquire and analyze data as well as forming with report and data curve. The transmitter can detect the real-time data of many monitoring points in a large area such as petroleum, chemical industry, electric power, hydrology and other fields requiring unattended and remote monitoring
