Monitoring of operating parameters at gas facilities, hydraulic and pneumatic systems, water treatment and heat supply systems, boiler automation, water utility automation and heating points where increased accuracy of pressure measurement is required.

Main advantages

• Data transfer to the collection server using GPRS or NB-IoT technology.
• Measurement of absolute pressure of media neutral to stainless steel AISI 316L (AISI 304S) (gases, steam, water, slightly aggressive liquids).
• Permissible overload 1.5 Rmax.
• Battery life up to 5 years (depending on the frequency of measurements and data transfer).
• The guaranteed number of data transfer sessions to the information collection server is 5,000, 7,500, 10,000.
• Possibility of charging the internal battery by the service department.

Online monitoring and alarm notifications

• The sensor will reliably inform you about the state of pressure and temperature in the resource supply networks.
• The measured data, according to a given schedule, is automatically transmitted via GSM / GPRS / NB-IoT to a secure collection server.
• The device receives from the server the setpoint values (pressure and temperature ranges), when they are exceeded, the dispatcher receives an interactive message and must take actions in accordance with the regulations.
• The system keeps a record of all events and actions taken.

Easy installation and use of the sensor

• Structurally, the device is made in a single housing, in which the sensitive element and the electronic conversion unit are located.
• Installation of the device is carried out similarly to the installation of a conventional pressure gauge.
• Thanks to its compact and robust design, as well as the explosion-proof housing (EX device version), the sensor can be used in difficult and hazardous environments.

Customizable device settings

• The dispatcher configures for each device the frequency of measurements, the schedule for transferring data to the server, and the boundary values for out-of-order data transfer.
• For each channel, you can set the minimum and maximum alarm threshold.

OPC UA server

Pressure and temperature sensors BBT-DDT, according to a given schedule, transmit the measured pressure and temperature values to the server via the GPRS/NB-IoT channel. Using the SCADA client through the OPC UA server, the system operator controls the adjustable parameters (alarm thresholds, polling period, operability confirmation period, period of data transmission in the accident zone) of autonomous BBT-DDT pressure and temperature sensors.

Secure server for collecting and processing data

• The data collection and processing server is implemented on the basis of the domestic platform Astra Linux Special Edition, certified according to the security requirements of the FSB, FSTEC of Russia for operating systems.
• Server software is provided free of charge for the entire period of operation of the device.
• There is no need to purchase additional licenses.
