With many suppliers of proximity sensors, it is necessary to use a separate transmitter for each system length, probe diameter, and target material due to the specific hardware configuration of the system. As a result, many types of drivers need to be kept in stock, but due to the high costs, this is often not done.
This results in machines sometimes being down for extended periods or maintenance being very time-consuming with significant financial consequences. With the Digital Proximity System (DPS) from Metrix, it is no longer necessary to have a separate transmitter in stock for each application, saving a lot of costs.
Digital Proximity System (DPS)
The system consists of three parts: a driver or transmitter, a sensor (proximity probe), and an extension cable. These are matched components that normally cannot be swapped with different components. Depending on the desired output, you should choose the driver MX2033 (voltage output) or the transmitter MX2034 (current output). Both models are fully compatible with a wide variety of sensors and cables from Metrix and other manufacturers.
The driver and transmitter can be easily configured digitally in the field via a USB connection. Using the DPS configuration software, only a few parameters need to be set, including target material, probe series, and cable length, after which the new configuration can be uploaded. A verification then needs to be performed to put the system back into operation. This video demonstrates the configuration process: https://youtu.be/FGvA1bC03jU
Due to the simple configuration, a lot of time and money is saved. Additionally, the DPS is fully compliant with API 670 and is compatible with a wide variety of sensors and cables from Metrix and other manufacturers (including BN). Therefore, it is not necessary to replace sensors and cabling when they are still functioning properly.
Fully compliant with API 670
The entire system is compliant with API 670, meeting the industry standard that specifies the requirements for machine monitoring systems for measuring radial shaft vibrations, housing vibrations, axial shaft position, RPM, and phase reference.
Interchangeable with other brands
The new MX8030 sensors and MX8031 triaxial extension cables with VibeLock connectors, as well as the MX2030 sensors and MX2031 extension cables, are fully interchangeable with Bently Nevada (BN) 7200, 3300, and 3300XL 5mm/8mm systems. This compatibility provides greater supplier choice for drivers without the need to replace the installed sensors and cabling.
Support for older sensors
Replacing a complete proximity transducer system can be very expensive and impractical. This is especially true when the machine must remain operational and sensors and cabling are mounted inside the machine. The DPS supports older sensor systems, cable lengths, and target materials using a single driver or transmitter.
System components
As mentioned earlier, the system consists of three parts: a driver or transmitter, a sensor (proximity probe), and an extension cable.
MX2033: 3-wire driver
The output signal of the MX2033 driver is compatible with industry-standard monitoring systems for continuous vibration monitoring and is API 670 compliant. The model uses -24Vdc excitation and provides the output signal in mV/µm with a typical sensitivity of 7.87 mV/µm.
Other sensitivities are programmable.
MX2034: 4-20 mA Transmitter (ATEX)
The MX2034 transmitter can be connected to any instrument that can handle a 4-20mA signal. It is therefore well-suited for connecting to PLCs, DCSs, and SCADA systems. The model can be configured by the user to function as a radial vibration transmitter (with the 4-20 mA signal proportional to vibration amplitude), as an axial position transmitter (with the 4-20 mA signal proportional to the distance between the shaft and probe), or as a tachometer (with the 4-20 mA signal proportional to RPM). A BNC connector allows the raw vibration signal to be forwarded to signal analysis equipment, portable data collectors, and test instrumentation.
Proximity probes (MX8030 and MX2030)
The MX8030 probe series consists of probes with diameters of 5 mm and 8 mm with VibeLock™ connectors and triax cables. The 8 mm probe is available in a ceramic tip version for use in demanding environments. Both probes offer a full range of 2 mm and are designed to provide fully API 670-compliant performance characteristics when used with a matching MX8031 extension cable and MX2033 driver. MX8030 probes are fully compatible with Bently Nevada* (BN) 3300 and 3300 XL 5 mm/8 mm probes.
The MX2030 probe series is the same as the MX8030 series, except it is used with a matching MX2031 extension cable and does not include VibeLock connectors or triax cables.
Extension cables (MX8031 and MX2031)
The MX8031 extension cables are available both with and without cable armor and feature VibeLock™ connectors and triax cables. They are compatible with all Metrix MX8030 series 5 mm and 8 mm probe systems, as well as Bently Nevada* (BN) 3300 / 3300XL 5 mm & 8 mm probe systems.
