CEMB TR-26/1/1/2/0 Vibration Transmitter

Name: CEMB TR-26 Vibration Transmitter 4-20mA – Datasheet & Quote
Brand: CEMB

Description

Overview

The CEMB TR-26 vibration transmitter is a compact industrial unit providing a single 4–20mA analog output proportional to machine vibration level, engineered for continuous condition monitoring of rotating equipment in process plants.

Designed for reliability and simplicity, the TR-26 is loop-powered from the receiving system, making installation as easy as wiring a conventional two-wire transmitter, with the output directly readable by any PLC or DCS analog input.

Engineering & Design

The TR-26 incorporates a piezoelectric sensing element with built-in signal conditioning that converts raw vibration into an industry-standard current loop signal, eliminating the need for separate vibration switches or external amplifiers.

Housed in a rugged industrial enclosure suited to plant floor environments, the unit requires no routine maintenance after installation and provides stable, repeatable readings over long operating periods.

Compatibility & Integration

The TR-26 connects to any standard 4–20mA analog input and can replace vibration switches and older amplifier-based transmitters in existing monitoring schemes without control system changes.

Monitoring Support

Seven Star LLC helps customers define the most suitable measurement parameter, whether velocity for ISO 10816 comparisons or acceleration for bearing condition monitoring, and determine correct alarm settings.

Our condition monitoring specialists also support data interpretation and trending so maintenance decisions are based on accurate machine health information.

Operational Benefits

The TR-26 provides a reliable, low-cost entry point into continuous vibration monitoring for critical and semi-critical machines, converting raw vibration into a universally readable 4–20mA signal.

Plant maintenance teams can trend machine condition in the same systems they already use for process variables, simplifying alarm management and daily review.

Its rugged design and maintenance-free operation reduce lifetime cost compared with handheld survey programmes.

Vibration data collected from the TR-26 supports trending, alarming, and maintenance planning, helping plants move from calendar-based to condition-based maintenance programmes.

Simple integration with existing analog input cards makes the TR-26 an economical upgrade path for unmonitored rotating equipment.

Continuous vibration data also supports early detection of imbalance, misalignment, and bearing wear before secondary damage occurs.

For plants where the CEMB TR-26 monitors critical machines, Seven Star LLC supplies the CEMB TR-26 with calibration certificates and mounting guidance.

The TR-26/1/1/2/0 transmitter measures the vibration with the piezo-electric sensor, and the transmitter provides the velocity output for the condition monitoring of the rotating machines.

The transmitter housing is suitable for the industrial environment, and the output is scaled for the standard monitoring range.

The CEMB TR-26 transmitter is used for the continuous vibration monitoring of the fans, the pumps and the motors, and the unit provides the standard 4-20 mA output.

The CEMB TR-26 vibration transmitter converts the vibration velocity to the 4-20 mA signal, and the CEMB TR-26 vibration transmitter is installed directly on the machine bearing housing for the continuous monitoring.

The CEMB TR-26 vibration transmitter is installed on the motor bearing, and the TR-26 unit is wired to the monitoring display.

Why Seven Star LLC

Seven Star LLC supplies genuine CEMB TR-26 vibration transmitters from our Muscat, Oman warehouse with calibration documentation.

Our condition monitoring specialists assist with sensor selection, alarm limit setting, and integration into your existing monitoring systems.

Confirming the Correct Model Code

The suffix in TR-26/1/1/2/0 describes the configuration of the transmitter, so a replacement should be matched to the complete code on the nameplate, not only to the TR-26 series name. Check the label of the installed unit, and confirm the measured quantity and full-scale range, the output wiring and the mounting arrangement with your loop drawings. If the nameplate is damaged, photos of the unit and its cable connection help identify it.

Installation and Commissioning

Mount the transmitter on a flat, clean, rigid surface as close as possible to the bearing being monitored, since vibration measured on thin covers or guards does not represent the machine condition. Use the recommended mounting method and tighten it firmly, and orient the sensing axis in the direction of interest, typically radial for most horizontal machines. Wire the 4–20mA loop with screened cable, earth the screen at one end only, and keep the cable away from motor power cables. During commissioning, check the loop current with the machine stopped and running, and set alarm and trip limits in the PLC or DCS based on machine type and the relevant vibration severity guidance.

Troubleshooting

Output below 4 mA or zero: check loop power, polarity and wiring continuity.
Erratic signal: look for a loose mounting, damaged cable or electrical interference.
Reading higher than a portable analyser measurement: confirm mounting location and the configured range.

If readings rise steadily, carry out a detailed analysis with a portable instrument before planning corrective maintenance.

Applications in Oman and the GCC

The CEMB TR-26 vibration transmitter is suited to cooling tower fans, air-cooled heat exchanger fans, pumps and blowers in water utilities, power plants, refineries and district cooling facilities, where continuous protection is needed without a full monitoring rack.

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.

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.
