Description

Overview

The CEMB TR-PRO vibration transmitter is a high-performance industrial unit designed for continuous monitoring of rotating machinery, delivering a loop-powered 4–20mA signal 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.

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.

About brand

CEMB is an Italian manufacturer of balancing machines and vibration analysis equipment, based in Mandello del Lario on Lake Como. Engineer Luigi Buzzi designed his first, patented balancing machine there in 1946, and the company took the CEMB name in 1947. It began building wheel balancers in 1952 and today has industrial balancing and garage equipment divisions.

Seven Star LLC lists CEMB vibration transmitters, a portable analyzer and balancer, and a horizontal balancing machine, and supplies them to maintenance teams and workshops in Oman as an independent supplier.

CEMB vibration transmitters and balancing equipment

Among the transmitters listed are the TR-26, the TR-27 and the TR-PRO. They are case-mounted sensors that convert absolute machine vibration into a 2-wire 4-20 mA signal for a PLC or DCS. The N600 is a portable instrument for vibration analysis and in-place balancing of rotors, the tool behind searches such as portable balancer Middle East. The Z5-TC is a horizontal dynamic balancing machine.

Where CEMB equipment is used

CEMB vibration transmitters are fitted on fans, blowers, pumps, electric motors, cooling tower gearboxes and similar auxiliary machines where a permanent protection signal is wanted without a full rack system. Portable balancers serve rotating equipment crews in power stations, cement plants and process plants in the GCC. Balancing machines go to motor rewind shops, fan builders and overhaul workshops.

Ordering CEMB parts: what we need

A transmitter code such as TR-26/1/1/2/0 is a configuration string, and every digit selects an option. Send it complete, with the measuring range, the unit (velocity in mm/s, RMS or peak), cable or connector type and length, and the hazardous area marking if the sensor sits in a classified zone. For a balancing machine we need rotor weight range, maximum diameter and length, journal diameters, drive type and the balancing tolerance you work to.
