GY15 duct pressure sensor

GY15 duct pressure sensors are used to detect pressure bureau of coal mine ventilation fan inside, to achieve continuous monitoring of air pressure within the duct to prevent damage caused by man-made duct run wind leakage phenomenon. To prevent accidents. Downhole pressure sensor suspension cassette equipment, in strict accordance with the relevant provisions should be used to prevent accidents. This instrument has a power-off function and live indicator display, namely within the duct when there is no wind, air pressure sensor signal can be fed back into the system and related equipment immediately cut off power to ensure safety in production. The main technical indicators duct pressure sensor, what does? (1) Measurement range: 4 ~ 15m / s; (2) measurement error: ± 2%; (3) Signal output: 1 / 5mA; 0 / 5mA; 5 / 10mA; 0 / 5V; 0 / 10V; passive contact (normally open); (4) output power control: a group of normally open and normally closed contacts 250V 0.5A (5) working voltage: DC12 ~ 18V; (6) Maximum transmission distance: ≥2000m; cables: PUYVR 3 × 1.0 mine fire-retardant rubber cables distributed inductance: 0.8mH / km; distributed capacitance: 0.1uF / km; DC resistance: 24Ω / km. (7) Related equipment: coal mine production safety monitoring system, after the Unit supporting compatible with the monitoring system.
