Product catalog summary
Overview
Meggitt Sensing Systems specializes in various measurement products including LVDTs, inertial systems, inclinometers, accelerometers, IMUs, MEMS sensors, servo-inclinometers, and conditioners. These products are applicable in sectors such as aerospace, energy, measurement, and railway.
Product Specifications
  • Electrical: Power supply is 2.2Vrms ±20% at 3500Hz ±50Hz.
  • Mechanical: Maximum mechanical loads are 30N in both axial and radial directions.
  • Temperature: Operating and storage temperatures range from -40°C to +100°C.
Applications
The SX36RV120 SI RVDT sensor is used for valve position measurement and steam turbine servo-valve control. It provides a sinusoidal signal with linear voltage over the measurement range, operating on an AC/AC mode.
Technical Details
The sensor is constructed from a light anodized alloy and outputs through a 20-meter ETFE isolated cable. It is suitable for use in surface industries and environments with gaseous explosive atmospheres (zone 1), with specific precautions for zone 0.
General Specifications at +25°C
  • Stroke: ±60°
  • Full scale: 120°
  • Non-linearity: ±1.5% of FS
  • Sensitivity: 2.5±0.25 mV/V/°
  • Zero null voltage: 10 mVrms max
  • Primary impedance: 140Ω
  • Secondary impedance: 720Ω
  • Primary resistance: 44±20% Ω
  • Secondary resistance: 330±20% Ω
Safety and Compatibility
The sensor must be paired with intrinsically safe devices, ensuring compatibility with intrinsic safety rules.
Selection Guide
The product reference for a stroke of ±60° is 690100644, suitable for Ex ia IIB or IIC environments with temperature classifications T6 to T4.

Catalog excerpts

(IS) SX36RV120 series-1

Aerospace Energy Measurement Railway • Electrical : Power supply: 2.2Vrms ±20% / 3500Hz ±50Hz • Mechanical : The mechanical loads applied to the axis must not exceed the following values: axial direction : 30N radial direction : 30N • Operating and storage temperatures: -40°/+100°C Applications Meggitt (Sensorex) (IS) SX36RV provides a sinusoidal signal, with a linear voltage over the measurement range. The primary is excited by an AC voltage, and is picked up by the secondary winding on the transformer principle; the position of the rotating core determines the transformer ratio of each secondary winding. As the secondaries are wound in opposition, the difference between the secondary outputs is proportional to the core angle, relative to the housing. The zero position is where each secondary voltage is equal and opposite. This is determinate in factory, and the position marked on both spindle and housing. This series works with an AC/AC mode, and the signal can be treated with the Meggitt (Sensorex) 690 210 266 signal conditioner. The sensor is made from a light anodized alloy. Output is given through a 20 meter ETFE isolated cable with gauge 26 copper wires. They can be used : - In surface industries - In permanent presence of gaseous explosive atmosphere (zone 1) (for a zone 0 use (*), please consult us) - With the gas listed in subdivisions IIB, IIC (*) the RVDT external housing includes aluminum; it shall be protected against any impact or friction.
