Pressure measurment

The transducer model got the gold medal in 2004 at the Nurnberg Exposure (Germany).

The main development of MVG Group — Compact high temperature transducer with flexible lead. The strain-gauge transducer. The sensing element is designed in prime-shaped form.

Our model has a number of advantages over the well-known modes of the transducers.

The line of our developments presents various modifications of an uncooled pressure transducer’s body. DMVG-160-500, these bodies are temperature and vibration resistant.

Pressure-measuring devise MVG-1

Pressure-measuring device MVG-1 is destined for comparable work with uncooled pressure transducer DMVG-160-500, set in the cage, which is linked with the cylinder combustion chamber of ICE.

Presented the models with connection of various number of transducers (from 1pc to 8 pcs).

Single-channel measuring device

Multiple-channel measuring device

Takes measurements by serial polling of the channels.

Pressure measuring device:

  1. Converts the signal produced by the pressure transducer DMVG-160—500 into analog output, which is contingent with the combustion chamber pressure.
  2. The information which corresponds to the full scale pressure in the chamber is indicated on the numeric display.
Performance specification
Indicating pressure on the display Мра 0 ÷ 20
Output voltage of analog signal В 0 ÷ 5
Power supply voltage В 18 ÷ 36
Protection against polarity reversal of power supply
