In China, the services provided by Yueyang Tongtu Company and the EPRO MMS 6620 can accurately receive the vibration signals of the casing measured by piezoelectric acceleration sensors and the temperature signals measured by thermistors, which helps you thoroughly identify potential dangers in the casing and bearing boxes. Welcome to inquire about the price.
This equipment is mostly used in rotating devices that are extremely sensitive to bearing wear and shell resonance. The most typical example is the radial and thrust bearing temperature monitoring and shell vibration monitoring of the high-speed centrifugal compressor units in large petrochemical plants, which are often used in conjunction with the shaft vibration module to form a dual protection system. There are also blast furnaces' blowers in steel mills, which have a low rotational speed but large impellers and are prone to shell resonance. They must rely on this to capture the shell vibration signals. In addition, on the feed water pump or induced draft fan in large thermal power plants, it is used to monitor the temperature of the motor bearing and the high-frequency vibration of the casing. For all critical parts that need to simultaneously monitor the mechanical structure vibration and friction heating conditions of the equipment, this EPRO MMS 6620 is a standard configuration.
Many overseas customers express their approval in emails after using our products. A North American condition monitoring engineer said that he used to change this module with temperature, the most afraid of the kind of board that looked new, but had an internal constant current source that caused the temperature reading to drift, which could drive people crazy. Troubleshooting could drive him crazy. But the EPRO MMS 6620 purchased from Tongtu in Yueyang, from the meticulousness of the packaging alone, can be seen to be sent by someone who is knowledgeable. After powering it on and using a standard signal source for testing, the temperature linearity was excellent, and the vibration frequency response was also very standard. This quality made people engaged in precise diagnosis think it very reliable. From now on, for such composite monitoring spare parts, they will definitely choose us.

The technical liaison personnel of our company are very familiar with the wiring principles of various thermal resistors and the matching of vibration sensors. For this composite module, the biggest concern at the site is that if the temperature channel is wired incorrectly, the measured values will fluctuate randomly. Please provide us with the nameplate and wiring method of the on-site sensors. Our engineers will immediately guide you on how to specifically allocate this three-wire thermal resistor on the terminals of the MMS 6620, which wire is for excitation and which is for measurement. If you find that the temperature display value at the site is several degrees different from the reading of the handheld temperature measuring gun, send us a screenshot of the settings interface. We can usually immediately point out whether it is due to the uncorrect compensation of the lead resistance or the incorrect setting of the range upper and lower limits.
