The thermal expansion monitor DF9032/03/03 is mainly designed for the steam turbine industry to measure the expansion displacement of the steam turbine unit. It can not only transmit in the near distance but also in the long distance. When the short distance transmission is selected, the intermediate frequency displacement sensor is used as the sensing element, and when the remote transmission is used, the Not easy to damage, good reliability, long service cycle, continuous use, and constant current output. The thermal expansion monitor DF9032/03/03 can accept the signal of two LVDT (DC linear displacement transmitter) to monitor the thermal deformation of the casing. The LVDT needs to be installed on both sides of the dead center of the casing. The difference between the two indicates the deformation of the casing. An alarm can be set to prompt the operator to take measures as soon as possible.
Range: -999.9mm¡«+999.9mm;
Accuracy: ±0.03mm;
Frequency response: 0¡«10Hz, ±1%
Thermal expansion monitor DF9032/03/03 application:
The function of the sensor is to convert the measurand of the rotating machinery into a device that can be used for signal output according to a certain law.
Parameter description of DF9032-03-03 thermal expansion monitor
working principle:
A speed sensor is a sensor that is sensitive to magnetic induction, magnetic field strength and magnetic flux, and can convert these signals into electrical signals.
Electrical indicators:
DC resistance: 200 to 550Ω(25¡æ)
Working temperature: -10 to +120¡æ
Physical indicators:
Weight: about 120g
Anti-vibration: 20g
Thread specification: M16×1
Gear material: The gear material should be a metal material with strong magnetic permeability.
Tooth shape: Involute tooth shape is the most suitable tooth shape. Using large modulus gears or using other tooth profiles will produce huge waveform distortion, which will hinder the measurement. If the spindle moves axially, it should be noted that the center of the magnetic pole should be in the center of the gear.
