  Explosion-Proof Access Control and Management System The explosion-proof access control and management system is designed for reading identifiers, performing identification, controlling an external actuator, and generating an electrical signal to a component of the automated process control system to provide subsequent notification to the control panel about authorized access to the controlled area. The operating principle of the system is based on a contactless (radio-frequency) method of reading a code from an electronic identifier, followed by an automatic comparison of the read code with the set of authorized codes and issuing an electrical signal to the external device. The system includes a power-saving mode with automatic transition. Exit from the power-saving mode occurs when the reader panel is touched with an identifier (card) or when a control signal is received from an external device. The system can operate either in standalone mode or in networked mode.

  Acoustic Sensor “NeuroAcustic – Ex” The “NeuroAcustic – Ex” acoustic sensor is designed for use in vibroacoustic diagnostic systems for continuous monitoring of the condition and operational integrity of components and mechanisms at facilities responsible for the transportation and distribution of heat carriers, including natural gas. The acoustic sensor is mounted on the monitored surface, detects sound waves through contact transmission, converts these sound waves into a standard audio signal, and transmits the signal to an external device. The sensor can be used at industrial process facilities, including hazardous gas distribution and gas consumption facilities. The acoustic sensor is designed to operate under the following environmental conditions: Maximum ambient temperature: +110 °C Minimum ambient temperature: −40 °C The parameters of the intrinsically safe electrical circuits comply with the following values: Input voltage (Ui), max: 12 V Input current (Ii), max: 0.02 A Input power (Pi), max: 0.1 W Internal capacitance (Ci), max: 0.065 µF Internal inductance (Li), max: 0.01 mH Technical Specifications: Overall dimensions: Ø27 × 35 mm Weight: 0.3 kg Degree of dust and moisture protection (IP rating): IP67 Supply voltage: 3–12 V Current consumption: 5 mA Operating frequency range: 100–6000 Hz intended for: - Thermal power plants, boiler houses, and gas distribution stations - Oil and gas and chemical industry enterprises - Companies specializing in equipment diagnostics - Industrial safety and IIoT (Industrial Internet of Things) systems

High Voltage Indicator High Voltage Indicator "IVN Protection" - an additional safety measure for the electrician when working at a transformer substation.  The indicator is designed to provide visual and audible signaling of the presence of high voltage on live parts of high-voltage equipment operating at a line voltage of 6–10 kV and a frequency of 50 Hz. The presence or absence of current flowing through the live parts does not affect the operation of the device. The indicator is used to visually verify the results of switching operations on power lines, sections, and parts of electrical installations, as well as to warn maintenance personnel of the presence of voltage on electrical parts before carrying out scheduled or unscheduled work. Design and Construction The device consists of three capacitive voltage dividers (one per phase) and a visual and audible signaling panel. Each capacitive divider and the indicator panel are housed in separate enclosures. The divider housing is designed as a support insulator. Both the dividers and the indicator panel are equipped with built-in connecting cables, which are used for installation and connection at the site. Operation The indicator provides simultaneous monitoring of the presence of nominal voltage on the live parts of all three phases of the electrical installation. When nominal voltage is present on the monitored live parts, the indicator panel produces a steady light signal in three primary colors (yellow, green, and red), corresponding to the phase color coding of electrical installations. Additionally, an audible alarm is activated when a high-voltage compartment door is opened, provided that the door is equipped with a position monitoring device such as a limit switch or reed door sensor. The audible signal is generated only if nominal voltage is present on the monitored live part. Optionally, the product package may include door position sensors. Installation and Application Mounting the indicator panel on the front panel of a switchgear cubicle or a prefabricated transformer substation makes the voltage indication more visible and attracts the attention of operating personnel before any work is carried out. The indicator panel may also be installed in relay protection and automation (RPA) compartments, low-voltage switchboards, and similar enclosures. Power Supply The device is self-powered and does not require an external power source. The indicator is energized directly from its connection to the live parts of the power line. Technical Specifications: Overall dimensions of the capacitive divider: 82 × 122.5 mm Overall dimensions of the indicator panel: 114.4 × 59 × 34 mm Length of the capacitive divider connecting cables: 300 mm Length of the indicator panel connecting cables: 3000 mm Weight of the capacitive divider: 0.7 kg Weight of the indicator panel: 0.5 kg Degree of dust and moisture protection (indicator panel): IP40 Number of capacitive dividers in the device: 3 pcs Number of indicator panels in the device: 1 pc Rated supply voltage (50 Hz): 6 or 10 kV Maximum continuous operating voltage applied to the poles: 10 kV Maximum test voltage: 42 kV Minimum operating voltage: 0.6 kV
