Digital Proximity System

The Digital Proximity System (DPS), one of our flagship products, combines the performance of an eddy-current proximity measurement system with the flexibility of digital configurability. It is suitable for many hazardous or extreme conditions, such as being fully submerged in LNG. It is fully compliant with the API 670 standard and offers full compatibility with probes and cables from other major manufacturers.

The Metrix Digital Proximity System (DPS) can support older systems, various cable lengths and target materials, using industry-revolutionizing technology that is reliable and field proven. You can order exactly what you need, and you can configure it in the field, making it the perfect spare part. The advantage of digital input over analog is that it creates a product that reduces maintenance costs and makes your life easier.

We serve various industries that use motors, turbines, fans, including cooling towers, pumps, and compressors. We provide a scalable and customizable offering that can monitor all rotating and reciprocating machinery. These industries include chemical, oil and gas, petrochemical, power generation, pulp and paper, manufacturing, other process industries, and water & wastewater. Metrix Vibration has over 57 years of experience providing equipment for machinery monitoring systems.

Types of Digital Proximity Sensors We Offer:

Our innovative DPS systems provide a reliable and field configurable software interface.

MX2033 3-Wire Driver

The Metrix proximity system can work with any monitor rack that is advertised to accept 200 mV/mil (7.87 mV/µm) or 100 mV/mil (3.93 mV/µm). It is proven to work with multiple different manufacturers that produce monitor rack vibration monitoring systems. 

MX2034 4-20 mA Transmitter

The Metrix MX2034 Proximity Transmitter is field configurable for radial vibration, axial position or speed measurements. It combines the performance of a fully API 670-compliant eddy-current proximity measurement system with the flexibility of digital configurability. Users can order exactly what they want, or they can configure their transmitter system in the field using Metrix’ free software. The MX2034 can be field configured for over 40 target materials, a variety of probe tip diameters, different manufacturers, extension cable lengths, and linear ranges. It is the ideal spare part.

The MX2034 is capable of eliminating cross-talk between two adjacently installed proximity probes, the dynamic output signal measured at the BNC can be configured for positive or negative polarity depending upon the application, and transient electrical spikes can be suppressed in the system because the sensor samples at such a high rate (18,000 times per second). There are many other advanced features of the MX2034 that customers can take advantage of to optimize the value of their transmitter system. Metrix has the probes, cables, and accessories to meet your needs.

MX8030 Proximity Probe

Metrix* MX8030 probe series consist of 5mm and 8mm tip diameter probes with VibeLock™* connectors and Triaxial Cables.  VibeLock™* ensures the proximity probe and extension cable connection is made properly and stays connected. No special tools are required.  The Triaxial Cable provides an extra protective barrier for the proximity probe cable system to prevent excessive wear during installation.

MX8031 Extension Cables

MX8031 Extension Cable System comes standard with VibeLock™* and Triaxial Cables. The VibeLock™* feature ensures a proximity probe and extension cable connection is made properly and stays connected. No special tools are required. The Triaxial Cable provides an extra layer of protection to help prevent excessive wear during installation and in high vibration areas.  The external shield of the Triaxial Cable is not used electrically, but it is used for additional physical cable/signal protection. 

TIGHTVIEW® Proximity System

The TIGHTVIEW® Proximity System was designed to fit very tight spaces and provide an excellent linear measurement compared to competitive products for similar applications.

MX2030 Probe Series

5 & 8mm tip diameter probes. Available in 5 and 9 meter system lengths.

MX2031 Cable Series

Extension cable available in 4, 4.5, 8 and 8.5 meters.
