Profile

The diaphragm seal is a pressure-transmitting, diaphragm-type device. The pressure signal is sent to the cooperating pressure measuring device (pressure transmitter, pressure gauge) through manometric liquid filling the space between the separating diaphragm of the seal and the pressure measuring device. The diaphragm seal task is to isolate the pressure measuring device from damaging impacts caused by either medium or installation:

• high coRrosiveness;
•  low or high temperature, increased viscosity, impurities; 
• vibrations of the installation (remote diaphragm seal).

The material of both diaphragms and contact faces for the chemical-resistant diaphragm seals is corrosion-resistant, considering the chemical composition of medium as well as its expected concentration range and temperature range.

S-CompCh seals are applicable for measuring the pressure of corrosive media. The wetted parts of the diaphragm seal are made of Teflon and tantalum. Several corrosive chemicals, except for hydrofluoric acid, gaseous fluorine and soda lye, can be measured.

The diaphragm seal task is to isolate the pressure measuring device from damaging impacts caused by either medium or installation:

• low or high temperature, increased viscosity, impurities; 
• vibrations of the installation (remote diaphragm seal); 
• pressure fluctuations.

S-Comp diaphragm seals have a large separating diaphragm (A70) while retaining a compact economic overall design. Benefits of S-Comp diaphragm seals include: 

• the ability to take measurements within a narrow range;
• simplicity of assembly.

S-RC diaphragm seals are applicable to the measurement of hot, viscous, solidifying or contaminated liquids, in any cases where an impulse line cannot be used.

The S-Mazut diaphragm seal is applicable to measurement of viscous liquids, at temperatures up to 150°C (300°C when remote diaphragm seal is used). A typical application is to measure the pressure of heavy fuel oil (petroleum atmospheric residue) in burners and in heat centres of power boilers.

3-valve and 5-valve manifolds are used where relative pressure transmitters are installed. They enable essential operations to be performed on the transmitters, such as starting up a transmitter or setting the zero position in conditions of static or atmospheric pressure. The five-valve manifold also enables a calibrator to be connected for metrological testing of the transmitter. The VM-3 and VM-5 have a modern lightweight construction. The high precision of manufacture enables individual valves to be opened and closed easily

The plug module BAK-Q80, BAK-Q60 controls and monitors fuel filler access on trucks, machinery, construction equipment. As an option, it can be equipped with additional event signaling devices for the driver and an anti-burglary strainer, both of which can also function as separate devices. “PLUG MODULE” and/or “CABIN SIGNALLING DEVICE MODULE” is connected to the monitoring system. “CABIN SIGNALLING DEVICE MODULE” has a preset number of elements for signaling events to the driver.

Fuel Level Converter is installed in the vehicle cabin right next to the control system recorder, so as to prevent any interference or voltage drop. A pulse from the pulse float in the fuel tank is sent to the input of Fuel Level Converter. The output of Fuel Level Converter should be connected to the voltage input of the recorder.
