    A range of stand alone thermometers answering the needs of OEM's, plant designers and process operators for a rugged, low cost temperature sensor which will integrate directly into a 4 to 20mA measuring, monitoring or control loop.

    Key Features

    • Range of standard through-the-lens sighting thermometers.
    • Range of fibroptic thermometers with optional laser targeting system.
    • Comprehensive range of thermometer mountings and accessories for complete environmental protection.
    • DIN-rail mounted power supply unit - DPU (optional).
    • LANDMARK Indicator LMi - digital panel meter (optional).

    Details

    The UNO range of thermometers is designed to satisfy all OEM requirements and has a wide selection of infrared radiation thermometers available.

    Each series of thermometers offers a choice of built-in time functions - peak picker or averager; and a range of temperature spans and operating wavebands to ensure optimum accuracy of measurement for the chosen industry and application.

    The standard range of UNO thermometers feature precision through-the-lens sighting with focusable optics, which guarantees exact viewing and measurement of the smallest of target areas.

    Adjustable emissivity/non-greyness compensation, peak picker and averager time functions are built-in as standard.

    The thermometer provides a 4 to 20 mA linear output. Thermometer type, temperature range, spectral response and optical characteristics are chosen to suit the particular application.

    Radiation Thermometers

    The thermometers utilize proven reliable electronics combined with a high quality optical system to provide accurate, dependable temperature measurement.

    They are housed in a rugged die cast body with a high quality electrical connector to provide reliable performance.

    The single wavelength and ratio thermometers all feature throughthe-lens sighting with a 6° field of view. Adjustable focus with a circular graticule gives precise alignment on to the smallest of targets.

    Two optical variants are available: Standard and Short-focus. Close focus lenses are also available permitting measurement of targets as small as 0.45mm/0.017in. Ask for separate leaflet for full information.

    Fibroptic Thermometers

    Fibroptic thermometers utilize a flexible fibre optics light guide enabling the detector and electronics enclosure to be located in a less hostile environment.

    The fibroptic thermometers are available with an optional built-in laser targeting system which defines the target spot for accurate sighting.

    The use of fibre optics permits viewing of normally inaccessible targets, where there are high magnetic fields or in high ambient temperatures up to 200°C/400°F without cooling of the optic head. There is a choice of three optic heads and three light guide lengths.

    Peak Picker

    The peak picker function is used when measuring the temperature of intermittent targets or where the hot target surface is obscured by cool areas such as scale on rolled steel.  The peak picker decay rate is adjustable from 1.5 to 30% of span per second.

    The peak picker function can be reset from a remote switch connected to the DPU.

    Averger

    The averager function is used to smooth unwanted variations or rapidly fluctuating changes in the thermometer signal to maintain a valid temperature reading.

    The averager time constant can be adjusted from 5ms (U1 and U2 thermometers) to 5 seconds to give a smooth temperature display.
