长沙LVDT8 micro transmitter displacement sensor

I. Overview of LVDT8 micro transmitter displacement sensor:

          Differential transformer displacement sensors (LVDT) can be widely used in crack measurement and monitoring, bridge measurement and monitoring, aerospace, machinery, construction, textiles, railways, coal, metallurgy, plastics, chemical engineering, and scientific research institutions in various industries of the national economy. They are used to measure high-tech products such as elongation, vibration, object thickness, and expansion.

            LVDT8 buckle mounted displacement sensor has excellent performance and is suitable for high-precision and high repeatability measurements in quality control and metrology applications. The measuring head adopts high hardness wear-resistant material silicon nitride ceramic, and the moving part of the measuring shaft adopts a precision guide rail. The pen displacement sensor is equipped with an external transmitter that can output standard DC signals. It uses a convenient single power supply+12-30V DC power supply, and the electronic circuit is sealed in a 304 stainless steel metal tube, which can work in harsh environments such as humidity and dust. The output signal is a standard 0-5V, 0-10V, 4-20mA or RS485 output that can be used by computers or PLC.

II. Characteristics of LVDT8 micro transmitter displacement sensor:

1. Outer diameter Φ 8mm pen shaped rebound displacement sensor

2. The probe is made of silicon nitride ceramic balls, which have good wear resistance

3. The measurement range is from 0-10MM, with high resolution and good repeatability

4. No sliding contacts, long service life

5. Power supply for AC signal, equipped with high-performance signal demodulator externally

6. Two wire 4-20mA current output, three wire 0-5V or 0-10V voltage output, and four wire RS485 signal output.

III. Application fields of LVDT8 micro transmitter displacement sensor:

        Axial runout detection, textile machinery detection, valve position detection and control, roller gap measurement, vehicle brake device wear measurement, robot and precision displacement measurement, online detection of automotive parts, machine tool and tool positioning, hydraulic cylinder positioning, bridge displacement detection, subway tunnel engineering protection

Selection guidance:

Wiring method:

Attention!!! The sensor pen and transmitter must be used together (with the same pen number as the transmitter number), and it is prohibited to exchange them randomly, otherwise the linear accuracy of the sensor will be severely distorted

V. Installation dimensions of LVDT8 micro transmitter displacement sensor:

LVDT8 tail straight line (without dust cover)

LVDT8 tail side line (without dust cover)

LVDT8 tail straight line (with dust cover)

LVDT8 tail side line (with dust cover)

PS: 1.  LVDT8 measuring pen without dust cover has a shorter length and added shielding function, solving the problem of mutual interference between measuring pens. More suitable for matrix installation scenarios, with a minimum installation spacing of 5-10mm for measuring pens. The vulnerable parts of the measuring pen, such as the iron core and spring, can be easily replaced.

2.  LVDT8 measuring pen with dust cover is more suitable for environments with dust. If matrix installation is required, the installation distance of each measuring pen should not be less than 40mm. If a smaller installation distance is required, additional shielding function needs to be customized.
