Specificationsexcess pressure transducer SDV-I "Kommunalets"

Overpressure transducers 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 a deformation of the sensitive element, causing a change in the electrical resistance of its strain gauges. At the output of the primary converter, an electrical signal appears, 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.

The design and coating of the transducers provide resistance to oils and detergents.
According to the degree of protection against ingress of dust and water, the converters correspond to the IP65 group.
The transducers 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 transducers are resistant to test pressure of 4.0 MPa for 15 minutes.
