• laboratory (analytical and precision);
• industrial platform scales;
• tube scales;
• crane scales;
• conveyor (belt) scales;
• vehicle scales – fully electronic and mechano-electronic (hybrid);

2. ADDITIONAL DEVICES RELATED TO THE SPECIFIC USE OF SCALES IN INDUSTRY AND TRADE – LABELING SYSTEMS, SOFTWARE PRODUCTS AND OTHERS.

3. NON-STANDARD WEIGHT AND FORCE MEASURING DEVICES AND EQUIPMENT:

• weight dosing systems;
• systems for weight monitoring of production;
• equipment for measuring forces, moments and flow;

4. AUTOMATION OF PROCESSES IN EXISTING PRODUCTIONS.

5. DEVELOPMENT OF NEW PRODUCTION LINES.

The company’s products are known on the market under the trademark “STIV”, registered in the Patent Office of the Republic of Bulgaria. The products manufactured under the “STIV” brand are certified by the respective metrological authorities and classification organizations, such as the National Center for Metrology, Bulgarian Ship Register, Lloyd’s Register and others.

The strong scientific knowledge in the development and production of force-measuring sensors and electronic instruments, as well as the extensive experience in servicing and operating weight-measuring devices, allow STIV Engineering to offer optimal solutions and resolve any issue related to weight measurement, force measurement and more.

Automated Systems

We offer design and turnkey construction of automated systems, belt scales, dosing systems and custom equipment.

ETHERINO NET-12-A

The device is intended for extending 12 signal lines through a local computer network.

ETHERINO NET-12-A has 12 individually galvanically isolated inputs and 12 outputs with relays with normally open contacts. When voltage is applied to one of the inputs, the relay of the corresponding output on the opposite module closes. If the connection drops, depending on the configuration, the outputs can retain their last valid states or switch to a predefined state. This function can be used to connect external signaling for a dropped connection with the opposite device.

Main characteristics

• 12 galvanically isolated inputs controlled by voltage. The inputs do not require polarity.
• 12 relay outputs
• LCD display showing the current state of inputs and outputs
• 10Mbit LAN port
• Serial port for configuration. In operating mode, the serial port provides a channel for asynchronous serial communication over the network (under development)
• Power supply DC 12–24 volts
• Free software for configuration, remote control and remote monitoring

ETHERINO MFC-6-A

The device is intended for extending 6 signal lines through a 4-wire communication line.

ETHERINO MFC-6-A has 6 individually galvanically isolated inputs and 6 outputs with relays with normally open contacts. When voltage is applied to one of the inputs, the relay of the corresponding output on the opposite module closes.

The communication signal between the devices is DTMF, which allows operation through multiplexers and channel concentrators.

The device has an additional relay output for connecting external signaling for connection loss.

Main characteristics

• 6 galvanically isolated inputs controlled by voltage. The inputs do not require polarity.
• 6 relay outputs
• LED indicators showing the current state of inputs and outputs
• Connector for connection to a 4-wire communication line
• Power supply DC 12–24 volts

Software

We offer development and implementation of application software.
