Specificationsoverpressure converter SDV-I "Kommunalets"

Excess pressure converters SDV-I "Kommunalets" They are a housing with a measuring unit and an electronic unit (EB) for signal processing.
The sensitive element of the measuring unit (pressure receiver) is the primary transducer. The sensitive element of the primary transducer is a plate with silicon film strain gauges, firmly connected to a metal membrane.
The pressure of the working medium on the measuring unit (pressure receiver) is converted into deformation of the sensing element, causing a change in the electrical resistance of its strain gauges. An electrical signal appears at the output of the primary converter, which is converted by the electronic unit into a current output electrical signal.
The electronic unit board is installed in the housing. To protect against environmental influences, a multi-layer protective coating is applied to the board.

For climate resistance SDV-I sensors correspond to UHL3.1 in the temperature range of the working environment from minus 50 to plus 80°C according to GOST 15150.
In terms of resistance and durability to the effects of ambient temperatures and humidity, the converters belong to groups C1, C4, B4 according to GOST R 52931.
The design and coating of the converters ensures resistance to oils and detergents.
In terms of protection against the penetration of dust and water, the converters correspond to group IP65.
The converters are designed to operate at atmospheric pressure from 66.0 to 106.7 kPa (from 498 to 800 mm Hg) and correspond to performance group P2 according to GOST R 52931.
The converters are resistant to test pressure of 4.0 MPa for 15 minutes.
The converters are durable and sealed after exposure to the maximum permissible overload pressure of 7.5 MPa for 1 minute.
