Soway SDVH20 Rebound LVDT Displacement Sensor Linear Variable Differential Transformer (LVDT)

describe:

Differential transformer displacement sensors (LVDT) can be widely used in various industries of the national economy such as aerospace, machinery, construction, textiles, railways, coal, metallurgy, plastics, chemical industry, and scientific research institutions to measure elongation, vibration, High-tech products for thickness, expansion, etc.

Pen-type displacement sensors offer excellent performance and are suitable for high-precision, highly repeatable measurements in quality control and metrology applications. The measuring head is made of high-hardness wear-resistant stainless steel material, and the moving part of the measuring axis adopts precision guide rails. The external transmitter of the pen-type displacement sensor is powered by 9~28 VDC, and the output signal is a standard 0-5V or 4-20 mA output that can be used by a computer or PLC.

Features:

●Outer diameter Φ20mm, stainless steel 304 shell, rebound type

● DC single power supply, built-in high-performance signal demodulator

● Three-wire voltage output 0-5V or 0-10V, two-wire current output 4-20mA

● Measuring range is from 0-100mm, high resolution and good repeatability

● No sliding contacts, long service life

application:

● Shaft diameter runout detection

●Hydraulic cylinder positioning

● Valve position detection and control

● Roll gap measurement

● Vehicle brake device wear measurement

Technical specifications:

Mechanical Dimensions:

1. The factory default setting is that the output increases when the sensor guide rod moves in the outlet direction.

2. The above dimensions are limited to analog output. If it is a digital output product, length A needs to be lengthened by 62mm.

* Note: Standard outer diameter size D1=20mm, can also be customized according to customer requirements.

installation method:

The positioning and installation of LVDT requires the use of non-metallic clamps with small temperature expansion coefficients. If metal block clamps are used for installation, the performance of the product will be affected. Our company has standard clamp accessories for users to choose from, and users can also customize the installation clamps.。
