Smart Trac: Technical Specifications
The Smart Trac is Tractian's line of IoT sensors for condition monitoring of industrial machines. Two generations are available:
Smart Trac UG1 — IoT sensor that monitors vibration, temperature, hour meter, and RPM.
Smart Trac UG2 — advanced generation with extended capabilities: ultrasound, magnetometer, broader measurement range, and Bluetooth/NFC connectivity.
Each sensor is identified by a unique code made up of three letters and four numbers (for example, BRX4242), located below the QR code on the sensor housing.
Smart Trac UG1
About the sensor
The Smart Trac UG1 is an IoT sensor that monitors vibration, temperature, hour meter, and RPM on industrial machines. It connects to the internet through the Smart Receiver, which automatically selects the best available cellular network.
Important: Do not use this device in environments with flammable gases, dust, or fiber-laden atmospheres. For hazardous areas, contact Tractian about the Smart Trac Ex sensor, which meets certification requirements for hazardous locations.

Environmental Characteristics
Attribute | Specification |
Protection rating | IP69K |
Surface temperature range | −40 °F to +248 °F (−40 °C to +120 °C) |
Ambient temperature range | −40 °F to +194 °F (−40 °C to +90 °C) |

About IP69K protection:
Full protection against solid particles, including dust.
Protection against rain, water jets, and steam.
Does not protect against submersion.
Safe Operating Range
Safe operation depends on the combination of surface temperature and ambient temperature. Even when each value is individually within the allowed range, certain combinations are not safe.
As a general rule: the higher the surface temperature, the lower the maximum allowed ambient temperature.

Important: Indoor range is significantly affected by physical obstacles such as metal walls, concrete structures, machines, and tanks. Maintain a direct line of sight between sensor and receiver whenever possible.
Chemical Resistance
The Smart Trac UG1 housing is resistant to a wide range of industrial chemicals, including common solvents, alcohols, oils, fuels, and detergents. Resistance levels vary depending on the substance.
Key points:
Resistance ratings apply to sensors installed using the screw mounting method.
Adhesive mounting is not recommended for environments with prolonged exposure to chlorine or substances with high oxidative potential.
Some strong acids (such as hydrofluoric, hydrochloric, and nitric acid) have low chemical resistance and may damage the housing.
For the full chemical resistance table, or to validate compatibility with a specific substance in your environment, contact Tractian Support.
Warning: Tractian is not liable for damage resulting from contact with materials classified as having low chemical resistance.
