HTD series displacement sensors convert mechanical measurement of liner movement into electrical power.
Through this principle, sensors measure and control displacement automatically. So it is widely used in industrial productions, defense constructions, research institutes and other aspects. HTD series displacement sensors have simple structure, high reliability, excellent usage and maintainability, long life, good linearity and high repeat precision. It also has a wide measuring range, low time constant and fast dynamic response.
THREE WIRE TYPE

Specifications
1. Linear range: 0~1000mm, 12 sizes.
2. Linearity: ± 0.3% full stroke.
3. Operating temperature: -40~150℃ (conventional) -40~210℃ (high temp)
4. Coefficient of sensitive: ± 0.03%FSO./℃
5. Lead wires: three Teflon insulated sheathed cable, outside stainless steel sheathed hose.
6. Vibration tolerance: 20g up to 2 kHz

Notes
1. Sensor wires: the blue wire is center tap.
2. Linear range: within two scale lines of the sensor rod (based on “Inlet”).
3. The sensor rod number and shell number must to be consistent, supporting the use.
4. Sensor fault diagnosis: measure RED-YEL coil resistance.
5. Keep sensor shell and signal demodulation unit away from strong magnetic fields.
