Linear Variable Differential Transformer Lvdt
φ8mm, with built-in springs and high-precision guides, this pneumatic displacement sensor offers excellent performance and is suitable for high-precision, repeatable measurements in quality control and metrology applications. The probe is constructed of high-hardness, wear-resistant stainless steel, and the measuring axis utilizes precision guides.
● 8mm outer diameter
● 1μm repeatability
● Available measuring ranges of 2, 5, 8, and 10 mm, with high resolution and excellent repeatability
● No sliding contacts, long service life
Strong and durable [reduced maintenance costs]
- Ball bearings extend service life
- Avoids damage caused by excessive tightening
- Product lifespan doubles that of traditional sensors
- IP67 housing
No errors [reduced downtime]
- No data loss during high-speed operation;
- No cumbersome adjustments or calibration required for initial use;
Lower total configuration cost [simplified installation, no I/O cards and PLC programming required]
Multiple signal outputs
Calculations do not require PLC programming
Small amplifier [no need to coordinate with other equipment for PLC programming]
Modular and miniaturized;
The output signal is a standard 0-5V or 4-20mA output that can be used by computers or PLCs.
Easy installation and operation, saving manpower
No matter how high-quality the sensor head is, if it's complicated to install or operate,
it can be difficult for field personnel to use. Thanks to its simplified installation and operation,
this series significantly saves labor.
The specially designed locking sleeve eliminates the need for a fixture.
The probe can be easily installed by drilling a 10mm diameter hole.

External Transmitter
This stylus-type displacement sensor (inductive probe) does not have an internal demodulator circuit. It requires an external transmitter, which connects via a socket. The sensor can output a standard 0-5V, 4-20mA, or digital signal (Modbus protocol) through the external transmitter.
Installation
LVDT positioning and installation requires the use of non-metallic fixtures with a low thermal expansion coefficient. Using metal fixtures can affect product performance. We offer standard fixture accessories for your selection, and custom fixtures are also available.
