LVDT8Q Pneumatic displacement sensor Installation size:
Pen displacement sensor (LVDT) outer diameter is 8mm, its own internal without a circuit demodulator, namely transmitter. The external transmitter is connected by means of an aviation plug. The pen type LVDT displacement sensor can output 0-5V, 0-10V, 4-20MA, RS485 signals through the external transmitter.
The positioning and installation of LVDT requires non-metal fixtures with small temperature expansion coefficient to be used for fixing. If the installation of metal fixtures will affect the product performance.
The company has a standard fixture accessories for users to choose to use, users can also customize the installation fixture.
