 Process Sensors

 

Process Sensors Corporation of is a premier manufacturer of IR temperature and thermal imaging products. They offer a wide range of simple to sophisticated, non-contact infrared temperature sensors to meet the most demanding on-line industrial process applications and OEM price/performance requirements. These are used in Environmental monitoring, Natural gas utilities, Power generation & Processing, Pulp & Paper manufacturing and other industries.

 Process Sensors Polaris

Polaris PS & PI Non-contact Infrared Heat Switch

The Polaris line is a cost-efficient and an accurate non contact infrared temperature switching device, for the recognition of hot parts. The short wave spectral sensitivity of these units is important for the precise detection of polished, bright metal parts, because the impact of emissivity deviation on accuracy is much lower in the near end infrared region. The Polaris temperature heat switch provides 2 transistor outputs and includes 2 yellow LED's on the back of the sensor indicating the switching position. Focus distances range from 6.7" (170mm) to 79" (2000mm) depending on the choice of selected optics. Spot sizes range from 1.3mm to 11mm. Available temperature ranges are from 300 °C to 1800°C.
