hese transducers are for displacement / position measurement. They make an accurate position measurement of the movement of the armature (the sliding part) relative to the body of the displacement transducer.
This transducer uses the Linear Variable Differential Transformer (LVDT) principle which means that it is probably the most robust ａnd reliable position sensor type available. The strength of the LVDT sensor＇s principle is that there is no electrical contact across the transducer position sensing element which for the user of the sensor means clean data, infinite resolution ａnd a very long life.
Our DC to DC LVDT transducer has all of the benefits of the LVDT sensor principle with the added convenience of built-in LVDT electronics enabling a dc supply ａnd dc output.
This series of displacement transducer is available as either an unguided, captive or spring return version. | | Unguided version.. |  | 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 | | DCTH100/1430 to DCTH400/1430 | | D1=31.75mm |  | | ID=2.54mm | | D3=2mm | | TF=M3 | | | DCV025U to DCV0400U | | 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 | | DCTH100/1430 | 5mm | <±0.5/±0.25/±0.1 | 83mm | 34mm | 207g | 3g | 18mm | 11.6mm | | DCTH200/1430 | 10mm | <±0.5/±0.25/±0.1 | 83mm | 34mm | 207g | 3g | 18mm | 9.0mm | | DCTH300/1430 | 15mm | <±0.5/±0.25/±0.1 | 83mm | 34mm | 207g | 3g | 18mm | 6.5mm | | DCTH400/1430 | 20mm | <±0.5/±0.25 | 83mm | 34mm | 207g | 3g | 18mm | 3.9mm | | DCV025U | 25mm | <±0.5/±0.25/±0.1 | 175mm | 43mm | 213g | 17g | 15mm | 16mm | | DCV050U | 50mm | <±0.5/±0.25/±0.1 | 203mm | 68mm | 270g | 23g | 15mm | 22mm | | DCV100U | 100mm | <±0.5/±0.25/±0.1 | 317mm | 81mm | 369g | 37g | 15mm | 16mm | | DCV150U | 150mm | <±0.5/±0.25/±0.1 | 430mm | 120mm | 497g | 55g | 15mm | 29mm | | DCV200U | 200mm | <±0.5/±0.25/±0.1 | 475mm | 132mm | 625g | 71g | 15mm | 16mm | | DCV300U | 300mm | <±0.5/±0.25 | 666mm | 183mm | 852g | 100g | 15mm | 16mm | | DCV400U | 400mm | <±0.5/±0.25 | 856mm | 259mm | 1.3kg | 140g | 29mm | 27mm |
| Captive guided version.. |  | Our captive guided displacement transducer has bearings to guide the armature inside the measurement sensor.
