Overview

The TD-III integrated three parameter combination probe is a highly integrated intelligent monitoring instrument designed specifically for critical state monitoring of rotating machinery. It innovatively integrates the measurement functions of three important parameters: vibration, temperature, and oil level. By outputting a standard 4-20mA signal, it can monitor the mechanical vibration amplitude, bearing temperature, and oil level status of the equipment in real time and accurately. Its compact structure, easy installation, significantly simplifies system wiring, improves monitoring reliability, and is widely used in predictive maintenance and safety protection systems for large equipment such as fans, pumps, and compressors.

Product Details

1、 Product Overview

The KR-939SB3 three parameter combination probe is a highly integrated industrial monitoring sensor designed for monitoring and protecting the status of rotating machinery such as fan gearboxes, water pumps, gearboxes, etc. This probe integrates measurement functions for temperature, oil level, and vibration parameters, and can directly output standard 4-20mA current signals, making it easy to connect to DCS, PLC, or computer monitoring systems to achieve real-time monitoring and fault warning of equipment operation.

2、 Core functions

1. Temperature monitoring:

·Measurement range: 0-100 ℃

·Accuracy: ± 1 ℃ (comprehensive error)

·Using platinum resistance sensors to ensure the stability and accuracy of temperature measurement.

2. Oil level monitoring:

·Measurement range: -10 to+40mm (0mm corresponds to the lower limit of normal oil level)

·Error: ≤± 5mm

·Based on the principle of thermal conductivity sensing, it is suitable for non-conductive lubricating oil.

3. Vibration monitoring:

·Measurement range: 0-20mm/s (RMS of vibration velocity)

·Frequency range: 10-1000Hz

·Error: ≤± 1mm/s

·Using magneto electric sensors, mechanical vibration signals are directly captured, filtered, and RMS converted before output.
