For use in manufacturing processes where the presence of glass is prohibited, Ircon has introduced a plastic lens for its Javelin infrared thermometer (Plate 5). This latest option enables the stainless steel bodied Javelin to provide accurate non-contact temperature measurement in a host of food, dairy and pharmaceutical applications.

Launched with an optical resolution of D/10, the plastic lens provides users with a fixed focal length of 2.5 m. Javelin’s advanced microprocessor backed circuitry ensures correct ambient temperature compensation and a calibrated accuracy of ±1 per cent and a repeatability of ±0.3 per cent.

Using Javelin’s two pushbuttons and integral LCD display, operators can configure the IR thermometer to meet the precise needs of the temperature measurement application.

Four settings can be selected: Peak Picker, for the consistent measurement of intermittent targets or those subject to interruption by environmental conditions; emissivity, between 0.1 and 1.0 in 0.01 increments; output response time, 165 ms to 10 s and the type of linear output, either 0-10 V or 4-20 mA.

In its ultra slim IP65 rated housing and measuring just 198 mm in length and 38 mm in diameter, the plastic lensed Javelin is easily integrated into harsh manufacturing environments. In extreme atmospheres, add-on air purge and air/water cooler options provide additional protection. To reduce set-up time, a laser-aiming accessory is also available.
