Description
Compact SDV “STANDARD” intelligent pressure transmitters are designed for measuring gauge pressure, ensuring accuracy, measurement stability, and a wide range of output interfaces for building modern systems of monitoring, automatic regulation, and commercial metering.
SDV pressure transmitters are supplied with valve blocks.
SDV-Ex transmitters belong to equipment group II and are designed for operation in explosive areas, with explosion protection type intrinsically safe electrical circuit “ia” and markings “0Ex ia IIC T5 Ga X” or “0Ex ia IIC T3 Ga X”.
Applications
-
Oil and gas industry (e.g., pressure monitoring in pipelines, process equipment, hydrocarbon preparation and transportation systems)
-
Power engineering (e.g., steam, water, and gas pressure monitoring in boiler plants, turbines, heating supply systems)
-
Railway transport (e.g., safety systems of rolling stock, pneumatic systems monitoring)
-
Aerospace industry (e.g., pressure measurement in aircraft hydraulic and pneumatic systems)
-
Metrological services accredited for verification and calibration of pressure measuring instruments
-
Automatic control systems for regulation and control of technological processes in gas, metallurgical, chemical, and food industries
-
Test stands (e.g., precision measurements in research and development projects)
Principle of Operation and Design
SDV “STANDARD” transmitters are based on the tenzo-resistive effect, using modern Russian silicon tenzo-resistive sensors. The sensing element is a silicon film resistor plate rigidly attached to a metallic diaphragm. When pressure is applied, the diaphragm deforms, changing the resistance of the tenzo-resistors, which is then converted into a unified output signal.
Metrological Characteristics
The transmitters ensure exceptional accuracy with errors from ±0.10% to ±1% of the measurement range. Temperature error is only 0.15%/10°C for analog outputs and 0.10%/10°C for digital interfaces.
Time between verifications (MTBV) is 5 years, confirming high stability of metrological performance.

-
Gauge pressure: Upper Range Limit (URL) up to 250 MPa
