MY5102 Chassis Thermal Expansion Sensor

The MY5102 thermal expansion sensor is mainly used to measure the expansion displacement of steam turbine cylinders. When combined with the HN-8 thermal expansion monitoring instrument, it can achieve remote indication, alarm, constant output and other functions of thermal expansion displacement.

Local indication has a large field of view, while remote indication is clear and intuitive in numerical form

Technical Specifications

Range: 0~50mm (range can be customized by the user)

Accuracy: ± 1% (full scale)

During the start-up and shutdown of a steam turbine, or during changes in a specific process, most machine casings undergo thermal expansion. If the expansion on both sides of the casing is uneven, the casing may become skewed or

Lifting up can cause significant stress between the casing and the foundation, resulting in misalignment and serious consequences. This undesirable situation is usually caused by the sliding pin system getting stuck

The result of 'astringency'. The HN-8 thermal expansion monitoring instrument uses a linear displacement sensor to measure the thermal expansion value of the casing relative to the foundation. The thermal expansion sensor needs to be installed on both sides of the platinum dead center of the casing

The difference indicates the deformation of the casing, and an alarm can be set to prompt the operator to take early measures. At the same time, it has standard current output, can be matched with various DCS and PLC systems, and has alarm and danger relay input

To ensure the safe and reliable operation of the machine.

Main functions

Monitoring and protection of thermal expansion of turbine casing

Functional Description

1. Display function

The vibration measurement value, I value alarm, and II value alarm set values can be displayed separately on the LED digital tube.

2. Alarm function

When the vibration exceeds the alarm set value, the alarm indicator light will turn on, and at the same time, a switch signal will be output on the rear panel to protect the monitored equipment.

3. Alarm delay time setting function

The alarm delay time adjustment range is 0-3 seconds to prevent false alarms caused by on-site interference.

4. Self diagnostic function

Equipped with power on and power off detection functions, while disconnecting the alarm output circuit, it can effectively suppress false alarms of the instrument.

5. Output interface

Equipped with a current output interface, it can be connected to devices such as computers, DCS, PLC systems, paperless recorders, etc
