这些传感器用于位移/位置测量。他们对位移传感器相对于位移传感器的运动(滑动部分)的运动进行了精确的测量。 该传感器采用线性变差变压器(LVDT)原理，这意味着它可能是*可靠、*可靠的位置传感器类型。LVDT传感器的原理是，传感器位置传感元件上没有电接触，传感器的用户是指清洁数据、无限分辨率和很长的生命。 我们的直流LVDT传感器具有LVDT传感器原理的所有优点，加上内置的LVDT电子设备，使直流电源和直流输出更加方便。作为一种选择，我们可以在某些型号的传感器上提供4-20ma 2线连接。 | |  | On our unguided LVDTs the armature assembly is a separate component, to make a measurement the user must guide the armature inside the body without touching the sides. Unguided position measurement transducers are appropriate where external guidance is available ａnd give truly non-contact operation | | DCTH100 to DCTH400 | | D1=20.6mm |  | | ID=2.54mm | | D3=2mm | | D4=2.0mm | | TF=M3x0.5 | | | DCTH500 to DCTH8000 | | A=9mm |  | | D1=20.6mm | | ID=6.8mm | | D3=4.75mm | | D4=5.97mm | | TF=M5x0.8 | | | | Type | Range | Linearity error (% F.S.) | L | X (nom) | Total weight | Armature weight | TF | Over-Travel | | Inward over-travel | | DCTH100 | ±2.5mm | <±0.5/±0.25/±0.1 | 64mm | 33mm | 74g | 1.4g | 18mm | 11.6mm | | DCTH200 | ±5mm | <±0.5/±0.25/±0.1 | 64mm | 33mm | 74g | 1.8g | 18mm | 9.0mm | | DCTH300 | ±7.5mm | <±0.5/±0.25/±0.1 | 64mm | 33mm | 74g | 1.8g | 18mm | 6.5mm | | DCTH400 | ±10mm | <±0.5/±0.25 | 64mm | 33mm | 74g | 1.9g | 18mm | 3.9mm | | DCTH500 | ±12.5mm | <±0.5/±0.25/±0.1 | 175mm | 43mm | 213g | 17g | 15mm | 16mm | | DCTH1000 | ±25mm | <±0.5/±0.25/±0.1 | 203mm | 69mm | 270g | 23g | 15mm | 22mm | | DCTH2000 | ±50mm | <±0.5/±0.25/±0.1 | 317mm | 81mm | 369g | 37g | 15mm | 16mm | | DCTH3000 | ±75mm | <±0.5/±0.25/±0.1 | 430mm | 119mm | 497g | 55g | 15mm | 29mm | | DCTH4000 | ±100mm | <±0.5/±0.25/±0.1 | 475mm | 132mm | 625g | 71g | 15mm | 16mm | | DCTH6000 | ±150mm | <±0.5/±0.25 | 666mm | 183mm | 852g | 100g | 15mm | 16mm | | DCTH8000 | ±200mm | <±0.5/±0.25 | 856mm | 259mm | 1.3kg | 140g | 29mm | 27mm |
