The Hydro-Line HLT IIEncapsulated Linear DisplacementTransducerHydro-Line HLT II linear displacement transducers areprecise, durable, cost-effective alternatives to linear potentiometers.In many applications, they can also replaceLVDTs and linear encoders. Well protected within the coreof the cylinder, the HLT II not only measures the positionof the moving elements of an actuation system, but alsoremains untouched, and unaffected by even the harshestelements. The innovative encapsulated design and engineeringalong with the rugged construction of Hydro-LineHLT II transducers guarantee the best reliability, precisionand durability in even the toughest industrial environments.In addition, problems associated with wear in linearpotentiometers, and cable routing and control in linearencoders are eliminated. Furthermore, HLT II modelsrequire no external signal conditioning. Whether positionsensing requirements are simple or complex, the Hydro-Line HLT II will help find solutions in a form factor andmounting configuration that fits any application.Improved DesignAs a leader in actuation products, Hydro-Line hasenhanced the design of the HLT II to deliver superior accuracyin linear displacement technology. The cylinder’scapabilities have been increased with a longer displacementrange (up to 142") and smaller non-linearity (±.02%).Absolute rather than incremental output eliminates theneed for re-homing in power-down situations. A non-contactsensing element virtually eliminates the wear, noiseand erroneous signal problems inherent in other linear displacementsensing devices.The HLT II transducer is available in either analog or digitalformat. Tighter precision, along with a higher operatingtemperature (now 185° F) and faster response time,make the Hydro-Line HLT II an ideal solution for a widerange of industrial applications requiring strict motion control.SpecificationsCharacteristicDescription/SpecificationSupply Voltage 24 Vdc ±20% or ±15 Vdc ±2% or ±12 Vdc ±2%Current Draw≤90 mA (≤1A inrush)Displacement Range2" to 142" strokeOutput Update≤1msNon-Linearity ±0.02%RepeatabilityResolution + HysteresisHysteresis < 0.00004"ResolutionAnalog: InfinitePulse: Defined by controlShock Rating100g /11ms (single hit)Vibration Rating12g (10 to 2,000Hz)Operating Pressure*3000 psi continuous, 8000 psi staticOperating Temperature-40 to 185°F (-40 to 85°C)Protection for Micro-Change NEMA 6P; IP68 (when cable is mated to connector)Connector and Cable AssemblyWashdown Pressure1000 psi (when cable is mated to connector)Molded Cable Assembly22 AWG, PVC insulated, metallic braid, fine stranded copper conductors, yellow PVCjacketed, 300 V, 3 amp, 105°C U.L. recognized, C.S.A. certifiedOutputsAnalog: 0 to +10Vdc, -10 to +10 Vdc , -5 to +5 Vdc, 4 to 20 mA, 0 to 20 mA( All analog outputs can be forward and reverse acting)Analog Adjustability: 15% adjustment of full scaleDigital: RS422 Start/Stop (leading or trailing edge active)Pulse-Width Modulated(Internal or External Interrogation with 2,4,6 or 8 recirculations)Maximum Cable LengthAnalog: Voltage output 50 feet, Current output 500 feetDigital: 1600 feetSpecifications are subject to change without notice.
