Ürün Tanımı

QBJ-3XRN Intelligent Thermal Expansion Monitor

Industrial equipment expansion monitoring and protection device for precise thermal expansion measurement and safeguarding of turbine systems.

System Overview

The QBJ-3XRN thermal expansion monitoring and protection instrument, equipped with TD-2 sensor technology, provides comprehensive measurement and protection against thermal expansion on both sides of turbine casings. Utilizing an AC linear variable differential transformer, this system accurately measures turbine casing expansion relative to the foundation along the axial direction. Transformers installed on both sides of the turbine centerline continuously monitor and display casing expansion changes throughout operational cycles from start-up to shutdown.

Technical Specifications

Measuring Range	0～35mm (customizable range available)
Accuracy	System error ≤1% (full scale)
Operating Environment	Instrument: -25℃～45℃, 80% relative humidity Sensor: -25℃～100℃, 90% relative humidity
Constant Current Output	4～20mA (compatible with DCS system passive contact)
Alarm Settings	Arbitrarily configurable within measuring range
Dimensions	160mm (W) × 80mm (H) × 260mm (D)
Opening Dimensions	153mm (W) × 77mm (H) × 260mm (D)
Power Supply	AC220V±10%/50Hz

Primary Functions

Travel displacement display with alarm and dangerous relay contact output
Current output correlation: 4-20mA corresponding to lower-upper measuring range limits
Power-on reset delay with normal indicator off; 5-second delay for lockout release upon recovery
Alarm danger values arbitrarily settable within measuring range
Customizable measuring range configuration
Automatic return to measurement state after 1 minute of inactivity in data setting view

Note: All technical parameters and functions are designed for reliable industrial operation in demanding turbine monitoring applications.
