Optical Sensors – Phototransistors have been an important platform for data acquisition and communication for various industrial sectors in the recent years. One of such products is the PT91-21B which is a self-latching smoke detector specially engineered to offer comprehensive and reliable safety solutions for home and industrial application. This infrared-based smoke detector incorporates a set of features that can help prevent false alarms from non-hazardous sources such as cooking fumes.

The PT91-21B includes a fan that is electronically activated when it detects smoke. This allows the detector to stay operational and ensure that maximum coverage is achieved for all areas. It also includes a dual relay output system that helps when two separate smoke sources are detected. This dual system ensures that a single smoke detector can cover more area than what a single detector alone can provide.

The PT91-21B application field is vast and includes: Home Security, Fire Prevention, Industrial Automation, Surveillance, Air Quality Monitoring, Medical Imaging, etc. This smoke detector is particularly relevant in industries where precision and accuracy are sorely needed. It is also a great projector for users who are looking for maximum coverage in detecting any smoke and fire hazards.

The working principle behind the PT91-21B is rather simple. The detector contains an infrared chambered that senses when smoke particles pass through it. Sensed signals are collected by specialized units located within the detector. These signals are processed accordingly so that the detector can either activate its alarm or simply remain in a standby mode.

In addition, the detectorthat transforms the sensed signals to a logic level compatible with home security and professional monitoring systems. This essentially means that whatever smoke particles that are detected can be accessed by above mentioned third-party systems; thereby providing additional monitoring and alarm capabilities.

The PT91-21B also provides users with an optimal solution for reducing false alarms. This is accomplished by incorporating sophisticated algorithms that utilize the device’s many specialized features. Such features include variable gain adjustment, noise filtering, environmental compensation, and auto-reset ability.

Overall, the PT91-21B is an excellent choice for any smoke detector application – all thanks to its unique features, reliable sensing capabilities, and low cost of ownership.
