Displacement Transducer
Displacement Transducers with very high accuracy to 0.01% (1 µm/10 mm), measuring range 10 mm or 30 mm, with essentially infinite resolution (non-incremental) for industrial and scientific users, f.e. creep testing machines
Product description
The Displacement Measurement Range of product consists of measurement transducer and their supporting electonics. UVB´s Dispalcement transducers provide high linearity, excellent long term stability and resolution of up to 1ppm of full range. The 4000 Serie Linear transducers are compact, robust sensors for use in applications ranging from metrology to heavy industry. Compared with other transducer systems, they are more stable, accurate and sensitive than LVDTs; longer lived, more robust and accurate than potentiometers; more compact and robust than optical laser systems. The production of these transducers 4000 Serie is a direct continuation of production of the UK company ASL (Automatic System Laboratories LTD.) in UVB TECHNIK.
Features
- Excellent Linearity of the transducers < 0.01 % of range, linearity curves are smooth and reach an optimum near to the center of travel
- Very High Accuracy < ± 1 µm in full range. All transducers are idividually verified by reference to gauge blocks.
- Excellent Resolution of up to 0.01 µm (1 ppm of range), non-granular
- The transducers are tolerant of wide temperature ranges, high magnetic fields and radio-active environments
- The transducers have superlative stability. The sophisticated construction has no windings, bobbins or magnetic circuit limitations
- The Robust Construction – The design of the internal elements has been optimised to absorb vibration by mounting them within a separate shock resistant cage (no electronic parts, no glas inside)
- The transducers can be mounted in any orientation
- Wide dynamic Range – which is supplemented by overtravel of 2 mm at each extreme
Advantages
- Materials: Standard electrode, body and shaft material is stainless steel (TC<12 ppm/°C)
- Temperature Range: Up to 100°C, storage up to 125°C
- Cables and Connectors: Three flexible Teflon insulated screened leads 2 mm diameter of standard lenght 3 metres (10 m max.) terminated with BNC plugs
- Anvils: Removable steel anvils (M 2.5) with ceramic ball tip, sintered diamond as option
- Return Springs: 100 ± 20 g at electrical zero and 40 ± 10 g at full electrical range (10 V)
- Bearing type: Precise linear ball bearing with dust excluding bellows
- Appropriate Signal Conditioner: Single channel UVB 4291 or dual channel UVB 4292
- Creep measurement and material testing systems (repair of MASL-14_24VDC and MASL-14_230VAC)

Signal Conditioners 4291, 4292
The Model 4291 & 4292 (upgraded 3291 & 3292) signal conditioners are use with UVB 4000 high accuracy transducers for Linear displacement measurement. These high performance units bring the advantages of these UVB transducers to a wider range of industrial and scientific users. When combined with UVB Transducers these units have great stability, sensitivity and resolution. These systems are robust, linear and high repeatable; have essentially infinite resolution; low temperature coefficient. The 4291 is the highest performance single channel device, 4292 is for dual channel operation. Creep measurement and material testing systems (repair of MASL-14_24VDC and MASL-14_230VAC). The voltage outputs for dual channel are A & B, (A+B)/2 or (A-B)/2 as option.
- All outputs are short circuit protected
