Metrix TXR-33505 Vibration Transmitter

Product Details

TXR-33505 Product Description

The Metrix TXR-33505 is a precision vibration transmitter engineered for seamless integration into industrial control architectures where machinery protection, predictive maintenance, and real-time condition monitoring are mission-critical requirements. Designed within the TXR Series platform, the TXR-33505 delivers a stable, loop-powered 4–20 mA output signal that interfaces directly with distributed control systems (DCS), programmable logic controllers (PLC), and safety instrumented systems (SIS), ensuring consistent signal fidelity across the full automation stack.

In modern industrial facilities — spanning power generation, petrochemical processing, water treatment, mining, metallurgy, and marine propulsion — rotating machinery represents the highest-value and highest-risk asset class. The TXR-33505 addresses this challenge by providing continuous vibration velocity measurement with a frequency response optimised for detecting imbalance, misalignment, bearing wear, and structural resonance before they escalate into unplanned downtime events. Its rugged stainless-steel housing and IP67-rated enclosure ensure reliable operation in harsh environments characterised by moisture, dust, chemical exposure, and mechanical shock.

The TXR-33505 is not a standalone instrument — it is a system-level component designed to function within a layered automation architecture. Its 4–20 mA analogue output integrates directly with the analogue input (AI) modules of leading DCS and PLC platforms, including Emerson DeltaV AI cards, Honeywell Experion AI modules, Siemens S7-300/S7-400 SM331 analogue input modules, and Rockwell Automation 1756-IF16 ControlLogix analogue input cards. This ensures that vibration data is captured at the control layer with the same signal conditioning infrastructure used for pressure, temperature, and flow measurements.

At the I/O layer, the TXR-33505 pairs naturally with remote I/O marshalling panels and field junction boxes, enabling multi-point vibration monitoring across large rotating equipment trains — such as compressor strings, pump arrays, and turbine-generator sets — without requiring dedicated vibration monitoring hardware at every measurement point. When deployed alongside Metrix MX2033 or MX2034 proximity probe drivers and Metrix 5550 series vibration monitors, the TXR-33505 extends the machinery protection architecture to cover both radial shaft displacement and housing vibration velocity in a unified monitoring strategy.

At the communication layer, the analogue signal from the TXR-33505 can be conditioned and converted to digital protocols — including HART, PROFIBUS PA, FOUNDATION Fieldbus, or Modbus RTU — using signal conditioners and protocol converters such as the Pepperl+Fuchs KFD2-STC4-Ex1 HART multiplexer or equivalent field device couplers. This enables the TXR-33505 to participate in asset management systems (AMS) and predictive maintenance platforms without requiring a dedicated vibration monitoring network.

At the power layer, the TXR-33505's 2-wire loop-powered design eliminates the need for a separate power supply at the field device, reducing wiring complexity and panel space. Standard 24 VDC instrument power supplies — such as the Phoenix Contact QUINT-PS series or Siemens SITOP PSU100S — provide adequate loop power for multi-drop configurations across long cable runs in large industrial facilities.

At the HMI and SCADA layer, vibration trend data from the TXR-33505 is visualised on operator workstations running platforms such as Wonderware InTouch, Ignition SCADA, or Emerson AMS Device Manager, enabling operations teams to track machinery health trends, configure alarm thresholds, and initiate maintenance work orders directly from the control room. Integration with OSIsoft PI or equivalent historian platforms allows long-term vibration data archiving for reliability engineering analysis and regulatory compliance reporting.

At the protection layer, the TXR-33505 signal can be routed to a Metrix 5550 Series or equivalent machinery protection system configured with high-vibration trip relays, providing automatic machine shutdown on vibration exceedance — a critical safety function in API 670-compliant machinery protection architectures for rotating equipment in oil and gas, power generation, and petrochemical applications.

Power Generation: In gas turbine and steam turbine generator sets, the TXR-33505 monitors bearing housing vibration velocity across multiple measurement planes, providing early warning of rotor imbalance, coupling misalignment, and bearing degradation. Its wide operating temperature range and IP67 rating ensure reliable operation in turbine enclosures subject to high ambient temperatures and steam ingress.

Petrochemical & Refinery: Centrifugal compressors, process pumps, and agitators in ATEX/IECEx-classified zones require continuous vibration monitoring to comply with API 670 and ISO 10816 machinery protection standards. The TXR-33505's stainless-steel construction and loop-powered design simplify installation in hazardous area junction boxes, reducing intrinsic safety barrier requirements compared to active IEPE accelerometer installations.

Water & Wastewater Treatment: Large vertical turbine pumps and horizontal split-case pumps in water treatment facilities benefit from continuous vibration monitoring to detect cavitation, impeller wear, and bearing failure. The TXR-33505 integrates with existing PLC-based SCADA systems without requiring additional vibration monitoring hardware, reducing total installed cost.

Mining & Minerals Processing: Conveyor drive motors, ball mill pinion bearings, and crusher drive assemblies operate in high-dust, high-vibration environments where sensor reliability is paramount. The TXR-33505's rugged housing and wide temperature range make it suitable for open-pit and underground mining applications where conventional instrumentation frequently fails.

Marine & Offshore: Propulsion shaft bearings, auxiliary diesel generators, and HVAC compressors on vessels and offshore platforms require continuous vibration monitoring for class society compliance and predictive maintenance. The TXR-33505's corrosion-resistant stainless-steel housing and IP67 rating meet the environmental requirements of marine installations.

Q1: Is the TXR-33505 compatible with existing DCS analogue input infrastructure without additional signal conditioning?Yes. The TXR-33505 provides a standard 4–20 mA, 2-wire loop-powered output that is directly compatible with any DCS or PLC analogue input card configured for 4–20 mA current loop inputs. No additional signal conditioning, transmitter power supply, or protocol converter is required for basic integration. The device operates on standard 24 VDC instrument loop power and is compatible with HART-enabled AI cards for optional device diagnostics.

Q2: How does the TXR-33505 fit into an API 670-compliant machinery protection architecture alongside dedicated vibration monitors?The TXR-33505 is designed to complement — not replace — dedicated machinery protection systems. In a layered architecture, the TXR-33505 provides continuous vibration velocity data to the DCS for process trending and alarm management, while a dedicated Metrix 5550 Series or equivalent machinery protection monitor provides the high-speed trip relay function required for API 670 compliance. This dual-layer approach ensures both process visibility and machine protection without compromising the independence of the safety shutdown function.

Q3: What warranty and supply chain support is available for the TXR-33505?All TXR-33505 units supplied by NANKMOS are covered by a 12-Month Warranty from the date of shipment, covering manufacturing defects and functional failures under normal operating conditions. NANKMOS maintains in-stock inventory of TXR Series components to support urgent replacement requirements, with expedited shipping available to global destinations. Pre-shipment functional testing is performed on all units, and full traceability documentation is provided upon request to support maintenance records and regulatory compliance requirements.
