CAMLogic Digital Revolution Monitor SMD20VN Series

Introduction – CAMLogic Digital Revolution Monitor SMD20VN Series

The CAMLogic Digital Revolution Monitor SMD20VN Series is a precision-engineered electronic speed monitoring solution designed to ensure the safe and reliable operation of conveyor systems and rotating machinery. Engineered by CAMLogic S.r.l. (Italy), this device continuously supervises the rotation or belt speed and activates a control relay if the detected speed drops below the configured threshold.

Built with robust powder-coated aluminium housing and rated IP65, the SMD20VN offers outstanding protection against dust and water jets, making it ideal for harsh industrial environments. Its design complies with ATEX standards for Zone 21 dust environments, ensuring safe use even in areas with potentially explosive powders.

This versatile unit features a set-point adjustment system that allows users to configure the monitored speed directly via three rotary selectors. Installation is quick and straightforward, requiring no special tools. The monitor can be easily mounted using an aluminium bracket, enabling flexible integration on conveyor belts or other rotating equipment.

Recognized for its high reliability and ease of configuration, the CAMLogic Digital Revolution Monitor SMD20VN is widely used in industries across the UAE and MENA region, supplied and supported by Dubai Sensor — a trusted distributor of industrial automation products.

FAQ – CAMLogic Digital Revolution Monitor SMD20VN Series

Q1: What is the function of the CAMLogic Digital Revolution Monitor SMD20VN?
A1: The SMD20VN monitors the speed of conveyor belts and rotating equipment. It activates a relay output if the measured speed falls below a preset threshold, ensuring safety and preventing equipment damage.

Q2: What is the measurable speed range of the SMD20VN?
A2: The device monitors belt speeds from 0.5 to 900 mm/s, making it suitable for most industrial conveyor systems.

Q3: Is the SMD20VN suitable for explosive or dusty environments?
A3: Yes. It is ATEX-certified (Ex II 2D Ex tD A21 IP65 T87°C) for Zone 21 dust atmospheres, offering safe operation in areas with combustible dusts or powders.

Q4: How do I configure the speed setpoint?
A4: The SMD20VN features three internal rotary selectors for hundreds, tens, and units, allowing easy adjustment of the desired threshold speed.

Q5: Does the unit require regular maintenance?
A5: No. The monitor is maintenance-free, as it uses permanently lubricated ball bearings and has no consumable components.
