Product catalog summary
Standard Options: The document outlines standard options for transducers, including radial cable outlets, pressure relief up to 2000 Bar, enhanced moisture and temperature resistance up to 200˚C, PTFE cable connections, and radiation resistance up to 100 Mrads. Axial or radial Bendix connectors are also available.
Special Products and Modifications: RDP Electronics offers minor modifications of standard products and special designs for OEM applications to meet specific customer needs.
‘Plug and Play’ Transducers: A new development based on IEEE 1451.4 Smart Transducer Interface features TEDS (Transducer Electronic Data Sheet) for automatic system setup, eliminating the need for on-site calibration.
Intrinsically Safe Applications: RDP provides LVDT-based displacement measurement systems for hazardous areas, requiring special system engineering and Zener Barriers.
Calibration Services: Calibration services traceable to NPL standards are available for displacement, load, and pressure transducers.
Approvals: All products are CE marked and comply with BS EN ISO 9001:2000 and relevant European standards and directives.
Product Range: The document lists various transducers, including displacement/position transducers, pressure transducers, non-contact position transducers, load cells, and accelerometers, highlighting the use of LVDT technology for precision and reliability in aerospace, automotive, and industrial control systems.
Specific Transducer Models: Detailed specifications for different transducer models are provided, including GT Precision Gauging Transducers, D5 and D6 Miniature LVDTs, D5 Submersible LVDTs, DCTH Miniature Displacement Transducers, and others, with descriptions of their linearity, repeatability, resolution, diameter, and specific applications.
High-Temperature and Submersible Transducers: Transducers suitable for high-temperature, cryogenic, and submersible applications are described, highlighting their construction, linearity, and specific use cases.
Magnetostrictive and Draw Wire Transducers: These transducers offer high accuracy and resolution for long stroke measurements, with various output options and applications in hydraulic actuators and machine tools.
Accessories: Mounting blocks for LVDTs are available for easy installation on flat surfaces.
Specifications: The document describes a linear spring motor with an output that is linear concerning the extension of the draw-wire. Output options include a potentiometer, voltage, 4 – 20 mA current, or digital readout, with standard ranges from 0.6 metres to 3.5 metres. Longer and special ranges, as well as low-cost versions, are available upon request.
Performance Metrics: Accuracy is typically 0.2% Full Scale (F.S), repeatability is 0.1% F.S, and resolution is 0.1% F.S.
Applications: The device is suitable for simple position control or measurement on special assembly machines, cut-to-length systems, restricted spaces, un-aligned systems, and measurement around corners.
Important Note: Due to RDP Electronics Ltd’s policy of continuous development, product specifications may change without prior notice. Any modifications may affect the specification of the equipment.

RDP - Displacement / Position Transducers-2

Suitable for use in very wet environments or withappropriate connections, completely submerged to a depth of up to 50 metres of fresh water. Ranges from 2 mm to 25 mm full stroke are available as free armature ђ or spring actuated ђ armature types. Fully sealed/welded, stainless steel construction throughout. In these pages you will find a huge range of devices - mostly based on inductivesensing principles - but complemented by the original MTS leading range of magnetostrictive displacement transducers, plus some non-contact capacitive based and resistive draw-wire types.It is the objective of...
