ABB TGM5 Angular Transmitter

Q: How do I adjust the zero point and measurement span on the ABB TGM5?

The zero point can be adjusted by approximately ±5% (referred to the output span) directly via internal adjustment potentiometers. While angular measuring spans are preset at the factory according to your exact ordering specification (e.g., 0–30°, 0–90°, 0–270°), adjustments can be recalibrated in the field by following ABB service procedures.

Q: Can the ABB TGM5-Ex be configured for 3-wire or 4-wire connections?

No. In accordance with intrinsic safety certification (PTB No. Ex-89.C.2148 / EEx ib IIC T4/T6), explosion-proof models (TGM 5-Ex) must be wired strictly in a 2-wire circuit powered through an intrinsically safe certified barrier (12 to 20 V DC max loop supply). Multi-wire circuits (3-wire and 4-wire) are only permitted on non-Ex models.

Description

Converting mechanical shaft rotations into linear electrical signals in demanding environments—from ship rudders and heavy cranes to rotary damper valves—demands an angle sensor built like an armored vault. The ABB TGM5 Angular Transmitter is engineered precisely for this caliber of extreme mechanical and climatic stress. Delivering precision non-linearity of less than 1% (and <0.5% on spans below 90°), this heavy-duty rotary transducer guarantees uninterrupted signal reliability where conventional optical or resistive encoders fail.

Whether monitoring continuous position feedback on commercial maritime vessels or managing heavy machinery in offshore installations across the GCC, Mohammad Mahdi Electronics (MME) provides dependable regional sourcing and fast supply for genuine ABB process instrumentation and specialized angle transmitter assemblies.

Engineered for Heavy Machinery & Maritime Environments

Unlike lighter industrial indicators (such as the TGE 5 or TGU 5), the TGM 5 series features an ultra-robust mechanical chassis (approx. 2.6 kg) engineered to withstand severe radial loads up to 300 N and axial shaft loads up to 900 N.

Extreme Climatic & Mechanical Resilience: Housed in a salt-water-proof, anodized cast aluminum enclosure rated up to IP66, tested to DIN IEC 68-2-27 shock (50 g/11 ms) and DIN IEC 68-2-6 vibration (5 g / ±10 mm / 5–150 Hz).
Exceptional Signal Accuracy: Delivers non-linearity <1% over the calibrated span, reducing to <0.5% for angle measurements below 90°. Long-term drift is bounded within <0.2% per year with high-speed step response under 50 ms.
Hazardous Area Certified (EEx ib IIC T4/T6): The intrinsically safe TGM 5-Ex version (Certificate PTB No. Ex-89.C.2148) is certified for Zone 1 and Zone 2 hazardous gas and vapor atmospheres.
Flexible Multi-Wire Current Loops: Field-configurable for 2-wire (4–20 mA), 3-wire, or 4-wire industrial circuits (0–5 mA, 0–10 mA, 0–20 mA, or 4–20 mA) operating from 12–36 V DC or 24 V AC.
Marine Certified Reliability: Available with Germanischer Lloyd (GL) maritime approval, making it the industry standard for rudder position indicators, variable-pitch propeller feedback, and winch controls.
Heavy-Duty Bearing Configurations: Available with friction bearings for extreme radial/axial load retention, or high-performance ball bearings for minimal breakaway torque down to 0.6 N·cm.

Primary Industrial & Marine Applications

Thanks to its saltwater-resistant housing and heavy shaft load limits, the ABB TGM 5 transmitter is deployed across critical control loops:

Marine Steering & Propulsion: Direct coupling to rudder stock indicators, azimuth thrusters, and valve control on commercial cargo and offshore vessels.
Cranes, Winches & Hoisting Systems: Heavy mechanical angle sensing for boom angles, slew rings, and rope drum rotation in harbors and industrial shipyards.
Process Dampers & Heavy Butterfly Valves: High-torque rotary positioning feedback in thermal power stations, petrochemical exhaust ducts, and flue gas dampers.
Weighing & Heavy Scale Systems: Translating mechanical mechanical shaft movement into standard 4–20 mA loops for PLC/SCADA integration.
