“CEMB” High performance vibration transmitter TR-PRO
Overview
The CEMB TR-PRO is a high-performance industrial vibration transmitter designed for continuous monitoring of rotating machinery, delivering two independent 4–20mA analog loops proportional to machine vibration level for direct connection to PLC, DCS, or SCADA systems.
Combining vibration velocity and acceleration measurement in a single compact transmitter, the TR-PRO provides cost-effective machinery protection for fans, pumps, motors, compressors, and general rotating equipment.
Engineering & Design
The TR-PRO integrates a high-sensitivity piezoelectric sensing element with dual-conditioning electronics, outputting RMS velocity in mm/s on the primary loop and acceleration in g on the secondary loop, with optional bearing condition monitoring via acceleration enveloping.
Its robust aluminium housing is certified for arduous industrial environments, and each unit is calibrated against traceable references during production, with ISM (Italian Ministry of Health) certification for safety-related applications.
Key Features
- Dual independent 4–20mA analog outputs for two vibration parameters
- RMS vibration velocity output in mm/s for ISO 10816 assessment
- Acceleration output in g with optional enveloping for bearing monitoring
- Direct PLC, DCS, and SCADA integration without external signal conditioners
- RS485 digital output for remote configuration and data acquisition
- ISM certified unit for safety-instrumented machinery monitoring
- Compact rugged housing for permanent installation
- Wide frequency response covering standard machine vibration bands
- Simplifies loop wiring with loop-powered or externally powered options
Applications
- Fans, blowers, and HVAC machinery
- Pumps and electric motors
- Compressors and gearboxes
- General rotating equipment condition monitoring

Condition Monitoring Support
Seven Star LLC provides machinery vibration assessment to define correct measurement points, mounting orientation, and ISO 10816 alarm thresholds for your rotating equipment.
Our specialists support integration with vibration monitoring systems and data acquisition platforms, helping your maintenance team act on reliable vibration data.
Operational Benefits
The TR-PRO enables condition-based maintenance by delivering real-time vibration data into the plant monitoring system, reducing unexpected failures and unplanned downtime of rotating equipment.
Two independent loops allow simultaneous velocity and acceleration assessment, so both ISO 10816 comparisons and bearing condition trending are available from a single device.
Simple two-wire installation and loop-powered operation reduce wiring cost and commissioning time compared with traditional vibration monitoring chains.
For plants where the CEMB TR-PRO must run without interruption, Seven Star LLC supplies the CEMB TR-PRO with calibration certificates, and our engineers help configure each CEMB TR-PRO for your machines and alarm levels.
The TR-PRO transmitter measures the vibration velocity of the machine, and the transmitter converts the vibration signal to the 4-20 mA output for the monitoring system.
The transmitter is supplied with the mounting stud and the cable, and the sensor measures the machine casing vibration.
The CEMB TR-PRO vibration transmitter is the industrial vibration transmitter with the analogue output, and the CEMB TR-PRO vibration transmitter measures the velocity of the machine vibration for the continuous condition monitoring.
The CEMB TR-PRO vibration transmitter is used for the pumps and the fans, and the TR-PRO transmitter provides the 4-20 mA signal to the PLC.
