They measure temperatures from -20°C to 500°C, accurately and consistently, with an outstanding response time of 240 ms. Two-way digital communications via a built-in RS 485 Modbus RTU interface enables the user to adjust the emissivity setting; compensate for reflected energy; apply filtering; select maximum, minimum, average or instantaneous readings; and peak or valley hold processing. Up to thirty two sensors can be installed on a single multidrop network. All PyroBus sensors are fitted with precision Germanium lenses for accurate optics. Model PB21 has 2:1 optics making it suitable for most applications where the sensor can be mounted close to the target. Model PB151 is designed for small or distant targets and has an optical resolution of 15:1. Model PB301 is designed for very small or distant targets and has an optical resolution of 30:1. These compact sensors are small enough to fit almost anywhere and their rugged stainless steel housings make them ideal for applications where cleanliness and hygiene are paramount. distance: sensor to object (inches) distance: sensor to object (mm) 11.9 45.2 78.6 0.5 1.8 3.1 0 19.7 39.4 0 500 1000 spot dia.
