RSS-designed smart vibration sensor

Russian Space Systems Holding specialists (RSS, part of Roscosmos) designed a digital mini-sized vibration sensor with the self-test mode. The sensor is supposed to be used in various industries as part of digitalization and has already proven its effectiveness and reliability under operating conditions of oil and gas industry. The product isshowcased at the MAKS-2019 Air Show at the RSS booth from August 30 to September 1, 2019.

Beside the necessary functions to show the observed value correctly, the smart vibration sensors normalize the signal, adjust the amplitude frequency response and perform self-testing. The sensors are produced by the NPO IT (part of RSS) and used in the oil and gas industry to ensure precise measuring of vibration parameters at various objects under heavy conditions – high power hits, under high and low temperatures, intense electromagnetic and static fields.

Beside low price,using the control sensors with a unified digital output ensures high interference protection and independence. Moreover, the vibration sensors have initially been created to measure vibration processes in rocket technology and aircraft that is why they are reliable and precise.

According to the NPO IT representative, Transneft company has been successfully using the smart vibration sensors since 2016. A new modification of sensors is being tested now, which is to be used in the Astra universal onboard telemetry system during the carrier rockets and spacecraft launches. Due to the ability to analyze the situation, the new digital sensor self-testing system allows enhancing its effectiveness and reliability”.

The sensor is a piezoelectric accelerometer with built-in electronics. The electronic module in the new digital sensors is located inside the head end of the sensor, which allowed substantial downsizing of the unit. The whole system is managed by a microprocessor that transforms the analogous signal into digital one, integrates the observed value, performs digital filtration and distributes the normed signal. The information is transmitted via the RS-485 interface using the Modbus RTUprotocol.
