First, the function and purpose:-B1 series of angular displacement level transmitter, all at home and abroad steel float level gauge supporting instruments, will be the scene of the measured level value converted by the transmitter Remote analog signal output for display unit or computer for display and control. It is with the float level gauge steel supporting the use of such instruments. Petroleum and chemical industry a variety of liquid medium tank level detection of the ideal instrument. 2. The transmitter can also be used to promote in other industries, because of its principle is to convert the mechanical rotation, said corresponding electrical signals, which can detect the angle and location of mechanical rotation. Special conditions according to applications and requirements, the transmitter a little adjustment, where appropriate, can detect objects within the distance of excitement, but also widely used in rivers, lakes, sea, ship, reservoirs and other large water gate control and water testing and other occasions. 
 Second, the main technical parameters: transmission range: 5m, 10m, 16m, 50m; output signal: 4 ~ 20Ma (two wire); transmission accuracy: 0.25, 0.5; Operating voltage: DC24V: -15% ~ 10 %; load resistance: 0 ~ 350Ω (output); Operating temperature: -40 ℃ ~ +60 ℃; Relative humidity: less than 90%; power consumption: about 0.8W; Dimension: I × B × h (mm ) 320 × 300 × 260; outlet hole size: ∮ 7.8mm; signal transmission cables: YQW3; explosion-proof grade and 证号: dIIBT4;.
