Metrix Product Announcement – Digital Proximity System 1.35


June 18, 2018—Houston, TX— Metrix has launched a new version of the Digital Proximity System, Version 1.35.  This product has the capability of replacing the proximity sensors at an entire plant, it is the universal spare part, with easy to use and free software.  When you consider that Metrix is known for making Vibration Monitoring easy, the DPS now makes Proximity sensing easy. 


 Imagine being able to support a multitude of older probe systems, cable lengths, and target materials with just a single device. The Metrix Digital Proximity System (DPS) allows the user to change the configuration in the field for use with any Metrix, or major competitor, proximity probe and cable.


 The Metrix DPS combines the performance of a fully API 670 compliant eddy-current proximity measurement system with the flexibility of digital configurability. Users can configure their transducer system in the field using a custom field-generated curve, as well as, factory pre-configured calibrations for a variety of probe tip diameters, manufacturers, extension cable lengths, target materials, and linear ranges.


Features of DPS 1.35 MX2033/MX2034:

  • Different Common Shaft Materials
  • Unknown Common Shaft Materials
  • Trimmable System Lengths
  • TightViewTM for Limited Clearances
  • Other Manufacturer’s Probes and Cables
  • Older Probes and Cables
  • Field Configurable Changes
  • Eliminate Crosstalk

Special Advanced DPS 1.35 MX2034 Transmitter Features: 

  • Invert Buffered Output Polarity – normal polarity is negative output at the BNC, this feature will allow the user to change the output polarity to positive.
  • Enable Spike Suppression – if enabled on the “vibration” selected transmitter, this feature allows the customer to suppress a random electrical spike, greater than the default scale range amplitude or an amplitude selected by the customer, for a short duration of time, usually 50 milliseconds up to 1 second.
  • 4-20 mAmp Direction – with a “position” selected transmitter, this feature allows one to set the full-scale range for Upscale (4 mAmp Low, 20 mAmp High) or Downscale (4 mAmp High, 20 mAmp Low).
  • Threshold – with a “speed” selected transmitter, this feature allows one to use an Auto Threshold setting, which will trigger the DPS with a large negative pulse, or Manual Threshold setting where the user can select the threshold value (usually -6 Vdc or greater) and a hysteresis band of up to +/- 2.5 Vdc for a negative going pulse.

Obtaining SIL 2, and SIL 3 capable, proves that the 5485C is now ready for use in safety system situations. The 5485C is designed to meet the expected functionality requirements using safety principles and introducing measures to limit or detect failures. All parts of the 5485C are thoroughly defined and designed to avoid systematic failures, and the dangerous failure modes are identified and eliminated as much as possible.

Engineering also outlines the production steps, tests procedures to be completed and the criteria to define if each sensor meets the expected requirements. A high number of safety requirements are necessary in the gas, chemical and oil industry. For these industries, safety is of serious importance, requiring a high level of safety for their control and monitoring systems.

About 5485C

The Metrix 5485C is a High-Temperature Velocity Sensor suitable for environments with temperatures up to 375°C.  It is designed for gas turbines and other machinery with high surface temperatures where a velocity signal is desired.  The Metrix 5485C is standard equipment on most heavy-duty industrial gas turbines. The sensor’s moving-coil design requires no external power as it self-generates a signal proportional to vibration velocity.

  TightView™ Proximity System
Minimize interferences commonly found in side obstructions or reduced counter bore areas with the New Metrix TightView™ Proximity System. This is the latest addition to our field-proven Digital Proximity System (DPS) family for measuring and monitoring radial vibration, thrust or shaft speed.
  VibeLock™ Connector and Triaxial Cables
New MX8030 Proximity Probe and MX8031 Extension Cable System comes standard with VibeLock™ Connector and Triaxial Cables.

The VibeLock Connector provides a secure, finger-tight, no slip connection between the probe cable connector and the extension cable connector. As you tighten the cable connectors, you will feel the ratcheting mechanism work until the connection is finger-tight. This will ensure the probe and extension cable stays connected until you are ready to take the connection apart.

The Triaxial Cable provides an extra protective barrier for the proximity probe cable system. The extra layer of protection helps prevent excessive physical wear during installation and signal protection in high vibration areas.
