Challenges and Solutions in Industrial Equipment Monitoring

In modern industrial production, equipment health monitoring has become an important link to ensure production safety and prevent unexpected shutdowns. The operational status of key rotating equipment such as blowers, gearboxes, and bearings directly affects the stability of the entire production line. Traditional monitoring methods often only obtain a single parameter and are difficult to fully reflect the equipment status. The 310VT series temperature vibration synchronous measurement sensor launched by Senser Technology provides a new solution for industrial equipment health management with its unique dual parameter monitoring capability.

Product core advantage: synchronous measurement of temperature and vibrationtechnology

The 310VT series sensor adopts a ceramic crystal with a circular shear mode as the sensing element. This design not only ensures long-term output stability, but also achieves synchronous and accurate measurement of vibration and temperature. The product has the following outstanding features:

Dual signal output: simultaneously providing 4-20mA current vibration speed signal and temperature signal

Durable design: laser welded stainless steel casing, IP68 protection level, suitable for harsh industrial environments

Broadband response: 10-1000Hz frequency range, covering most industrial equipment vibration monitoring needs

Anti interference design: EMI/RFI shielding, signal ground isolated from the casing to ensure signal purity

Typical application scenario analysis

1. Monitoring of blower system

Blowers are core equipment in many industrial processes, and issues such as unbalanced impellers and bearing wear can manifest as vibrations at specific frequencies. The wideband response characteristics of the 310VT sensor can accurately capture these abnormal vibration signals and monitor changes in bearing temperature. When the vibration speed exceeds 0.5 in/sec (12.7 mm/sec) or the temperature rises abnormally, the system can provide early warning to avoid sudden failures.

2. Gearbox health diagnosis

Gearbox faults often manifest as an increase in specific harmonic components in the vibration signal. The 310VT series offers multiple range options from 0.5in/sec to 10in/sec (254mm/sec), and users can choose the appropriate model based on the gearbox specifications. The temperature monitoring function can also detect overheating caused by poor lubrication, achieving dual monitoring of gear wear and lubrication status.

3. Bearing condition monitoring

The development of bearing faults usually goes through four stages, and the vibration characteristics gradually develop from high-frequency signals to obvious low-frequency vibrations. The ± 500g vibration limit and ± 2000g impact limit design of the 310VT sensor enable it to withstand high-frequency impact signals generated by early bearing failures, while accurately capturing low-frequency vibrations that develop later.

System Integration Solution

The 310VT sensor can be used in conjunction with various data acquisition systems to form a complete device health monitoring solution:

Portable detection: With the IN-91 portable vibration analyzer, it can achieve rapid on-site diagnosis,IN-91

Online monitoring: Connect the IN-SDG 8-channel data acquisition system, build a continuous monitoring network, and use the IN-SDG intelligent vibration transmitter from Senser Technology

Remote monitoring: connected to PLC or DCS system through standard 4-20mA signal

Suggestions for measuring system configuration:

DC power supply → signal conditioner → data collector → computer analysis system

Installation and Selection Guide

The 310VT series offers multiple installation options to meet the needs of different scenarios:

Standard configuration: Optional 1/4-28 to 1/4-28 or M6 mounting bolts

Special requirement: Optional M10 mounting stud or MB0001 magnetic seat

Wiring scheme: The 24A series comes with a 10 meter length option for easy on-site wiring

Selection example: For monitoring small and medium-sized gearboxes, the 310VT-1B model can be selected, which has a range of 1 in/sec and is equipped with M6 mounting bolts; For large fans, it is recommended to choose 310VT-10A with a 10 in/sec range and 1/4-28 standard bolts.

Technical parameter analysis

The 310VT series performs well under 24 ℃ and 15Vdc power supply conditions:

Vibration signal: Full scale output of 16mA ± 5%, nonlinearity of only ± 1%

Temperature monitoring: Sensitivity of 0.1mA/℃, wide range of -40 ℃~+125 ℃, accuracy of ± 2 ℃

Environmental adaptability: -40~85 ℃ working temperature, suitable for the vast majority of industrial scenarios

Maintenance and calibration recommendations

To ensure long-term measurement accuracy, it is recommended to:

1. Regularly check the installation and fastening status of sensors

2. Perform calibration verification every 12 months

3. Check the sealing condition of the connector to prevent moisture from entering

4. Use the standard calibration parameter table for data correction

The cornerstone of monitoring in intelligent manufacturing

The 310VT series temperature vibration synchronous sensor is becoming an important tool for equipment health management in the Industry 4.0 era due to its performance and reliability. Through the collaborative analysis of vibration and temperature parameters, equipment maintenance personnel can more accurately determine the type and development stage of faults, achieve the transition from 'regular maintenance' to 'predictive maintenance', save a lot of maintenance costs for enterprises, and improve production safety. With the development of industrial Internet of Things, this highly integrated intelligent sensor will play an increasingly important role in the field of intelligent manufacturing.
