商品説明The OS211 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 935ºF), accurately and consistently, with an outstanding response time of 240 ms. Two-way digital communications via a built-in RS485 MODBUS RTU interface enables the user to adjust the emissivity setting; compensate for reflected energy; apply filtering; select maximum and minimum, average or instantaneous readings; and peak or valley hold processing. Up to 32 sensors can be installed on a single multidrop network. All the IR sensors are fitted with precision germanium lenses for accurate optics. 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.
