This Series is a range of high quality, low cost, compact sensors which measure the temperature of inaccessible or moving objects and materials. They measure temperatures from -20 to 500°C (-4 to 932ºF), accurately and consistently, with an outstanding response time of 240 ms. Infrared (IR) sensors are available as either 2- or 4-wire units. Two-wire IR sensors transmit the target temperature as a 4 to 20 mA output and offer a simple solution for most non-contact temperature measurement applications. Four-wire IR sensors transmit the target temperature as a 0 to 50 mV or thermocouple output (Type J, K or T) plus the internal sensor temperature as a 4 to 20 mA output. This second output can be used to ensure that the sensor is being operated within the correct ambient temperature limits and prevent damage caused by overheating or overcooling. It can also be used to give an approximate indication of the air temperature surrounding the sensor. IR sensors are fitted with precision germanium lenses for accurate optics.

## **Adjustable Mounting Bracket** 

## **Fixed Mounting Bracket** 

The L-shaped fixed mounting bracket offers a rigid support for the sensor and allows fine adjustment in a single plane. 

The adjustable mounting bracket consists of a fixed mounting bracket plus another L-shaped bracket. When assembled as shown the adjustable mounting bracket offers a rigid support for the sensor and allows fine adjustment in two planes. 

**Option “WC” air/water cooled OS210-APSN jacket, additional cost. Air Water Cooled Housing** — C The air/water cooled housing allows the sensor to withstand @Q LA ambient temperatures which exceed the normal 70°C limit. Air or D> water (depending on the degree of cooling required) flows into one of the fittings on the side and out of the other. To prevent **Air Purge Collar** condensation forming on the lens, the air/water cooled housing is The air purge collar is used to keep dust, fumes, moisture and supplied complete with an air purge collar. Please note, the air/ other contaminants away from the lens. Air flows into the fitting water cooled housing must be ordered with the sensor and cannot on the side and out of the aperture at the front. be fitted by the user. 

## **Laser Sighting Tool** 

The laser sighting tool screws onto the front of the sensor during installation and indicates precisely where the sensor is aiming. Once the sensor has been aimed at the centre of the target and locked in position the laser sighting tool can be removed. The laser is activated by means of a push button on the front of the tool which has a latching mechanism.
