Turck CMVT-QR20 Vibration & Temperature Sensor
Overview
The Turck CMVT-QR20 is a compact condition monitoring sensor that continuously measures vibration and temperature on rotating machinery, giving maintenance teams the early warning needed to prevent unplanned downtime. Detecting acceleration and velocity across three axes with an RMS measuring range up to 16 g and a temperature range of -40°C to +85°C, the CMVT-QR20 transmits process data via IO-Link and/or simple switching outputs, making it equally suited to new IIoT-enabled installations and retrofits onto existing PLC-based systems.
As the official authorized partner and exclusive regional representative for Turck, Seven Star LLC proudly supplies the CMVT-QR20 vibration and temperature sensor to rotating equipment reliability teams and maintenance departments across Oman and the wider GCC. Every sensor shipped from our Muscat-based instrumentation division includes full factory documentation, and our technical team supports IO-Link master selection, threshold configuration, and installation for clients throughout the Sultanate of Oman.
Turck CMVT-QR20 Operating Principle
The Turck CMVT-QR20 uses an internal MEMS accelerometer sampling at 6.6 kHz to capture raw vibration data across all three spatial axes simultaneously, then computes RMS acceleration (up to 16 g) and RMS velocity (up to 320 mm/s at 78 Hz) values on board before transmitting the processed results. A co-located temperature sensor monitors housing temperature across -40°C to +85°C, giving a combined mechanical and thermal health signature for the monitored asset from a single compact device. Both vibration and temperature values, along with warning and alarm status, are transmitted over the standardized IO-Link protocol to a compatible master or gateway.
Because the alarm and warning thresholds are freely parameterizable through IO-Link, plant reliability engineers can tailor trip points to the specific ISO 10816-3 vibration severity zone applicable to each machine class, rather than relying on a fixed factory setting. In SIO mode, the sensor also outputs simple PNP/NPN switching signals for direct wiring into existing relay logic or PLC digital inputs where a full IO-Link infrastructure is not yet in place, allowing a phased migration toward condition-based maintenance without replacing existing control wiring.
Engineering Design of the Turck CMVT-QR20
The Turck CMVT-QR20 is housed in a rectangular, chemical-resistant Ultem plastic enclosure measuring 71.6 x 62.6 x 20 mm, engineered for direct bolt-on or magnetic mounting to motor housings, pump casings, gearboxes, and compressor frames. A single M12 x 1 male connector provides both power and IO-Link communication through a standard 4-pin cable, simplifying installation and reducing the wiring footprint compared to traditional vibration monitoring systems that require separate signal conditioning modules.
The sensor is rated IP68 and IP69K, withstanding both continuous submersion and high-pressure washdown, and is qualified to 200 g shock resistance and 20 g vibration resistance across 5 hours per axis, ensuring the monitoring device itself survives the same harsh conditions as the machinery it protects. Two status LEDs provide local visual indication of power and switching state, and an optional magnetic mounting kit (MAGKIT-M5) allows tool-free installation and relocation during commissioning or troubleshooting without drilling additional mounting holes.
Key Features
The Turck CMVT-QR20 vibration and temperature sensor equips rotating equipment reliability programs with a rugged, IO-Link-ready condition monitoring platform, and the Turck CMVT-QR20 is built for continuous duty:
- Measures RMS acceleration up to 16 g and RMS velocity up to 320 mm/s across three axes simultaneously.
- Monitors housing temperature from -40°C to +85°C alongside vibration data from a single compact sensor.
- Transmits process values and diagnostic status via standardized IO-Link, with SIO-mode PNP/NPN switching outputs for legacy wiring.
- Supports freely parameterizable warning and alarm thresholds tailored to ISO 10816-3 machine severity zones.
- Is rated IP68/IP69K for continuous submersion and high-pressure washdown durability.
- Withstands 200 g shock and 20 g vibration resistance, ensuring reliable operation on the same machinery it monitors.
- Connects via a single M12 x 1 4-pin connector for combined power and data, minimizing installation wiring.
- Offers a magnetic mounting accessory for tool-free installation and relocation during commissioning.
Industrial Applications
The Turck CMVT-QR20 is widely deployed for predictive maintenance on pumps, electric motors, compressors, and engines across oil and gas production facilities, power generation plants, and manufacturing lines. Its washdown-rated IP69K housing also makes it suitable for food, beverage, and water treatment facilities where equipment is regularly cleaned with high-pressure spray, extending condition monitoring coverage into hygienic and district cooling plant environments common across the region.
As the officially authorized partner for Turck, Seven Star LLC distributes the CMVT-QR20 vibration and temperature sensor to reliability engineering teams, RO desalination operators, and industrial plants across Muscat, the Sohar and Salalah economic zones, and neighboring GCC markets. Our regional stock holding and IO-Link integration support mean clients receive genuine Turck hardware with full manufacturer traceability, backed by local technical assistance rather than a distant overseas distributor.
