Low Differential Pressure Transmitter/Transducer

Low Differential Pressure Transmitter
For measuring very small pressure differences between two measurement points
either side of a ventilation fan, both sides of an air filter or either side of
clean room wall. Owning very strong R&D Center, Senba has become the most
advanced pressure transmitter manufacturer specialized in PIR sensor in China.

FAQ
Is Wave Soldering Recommended?
Wave soldering is likely to cause degradation of product performance. Wave
soldering is not recommended. Generally we recommend to solder by hand.

Can PIR Sensor Detect Animals?
PIR sensors are excellent in human and animal detection. They are mostly used
in triggering an intruder alarm and activate household appliances upon the
presence of a human.

Do PIR Sensors Work Through Glass?
No, alarm motion sensors do not work through glass. Most motion sensors use
passive infrared (PIR) technology to detect motion. Changes in IR energy are
not easily detected through glass. This is why motion sensors will generally
not work through windows, which are usually insulated.

What Is The Package?
1. PIR sensor: Graphic Carton-> Carton
2. LDR: plastic bag -> Graphic Carton -> Carton
3. Fresnel Lens: plastic bag -> Carton

What are the Factors that Affect the Performance of the Product?
1. When there is dirt on the window, it will affect the detection performance.
2. When the ambient temperature and the human body temperature are close, the
detection and sensitivity are significantly reduced, sometimes causing short-
term failure. The recommended minimum temperature difference between the
ambient temperature and the human body temperature needs to reach at least 4 °
C.
3. When designing the circuit, pay attention to anti-interference measures to
prevent false alarms caused by radio frequency interference.
