Citpo focuses on the research and development of FBG monitoring technology. The developed products include Water Pressure Gauge, Tandem Water Pressure Gauge, Inclinometer, Extensometer, Strain Gauge, Ground Anchor Load Gauge, Packer (installed with Tandem Pressure Gauge), Ground Two-Way Inclinometer, Differential Subsidence Meters and Accelerometers. It has been widely used in various real-time monitoring technologies such as reservoir safety monitoring, urban sewer, flood monitoring, hydraulic structure monitoring, and underground stratified water pressure changes.

• FBG pressure sensor

  A drinking water treatment system is a water treatment device that includes both point-of-use (POU) and point-of-entry (POE) units, such as reverse osmosis (RO), water dispensers, filtration systems, water pitchers, etc. These systems comply with various standards, including NSF/ANSI 42, NSF P231, P477, NSF/JWPA P72, and CSA B483.1.

  

  Features:

  1. The signal is reliable and does not need to be corrected
  2. Fast dry-wet conversion speed
  3. Not affected by temperature
  4. It can be used with Packer to monitor the pressure of groundwater stratification. After the Packer is deflated, the whole string can be taken out for maintenance
  5. Use pressure difference to improve measurement accuracy
• FBG in-place-inclinometer array

  FBG in-place-inclinometer array has biaxial inclinometer function, the shell is made of hard-oxidized aluminum alloy, and it can measure the inclination angle change of the structure with the exclusive holder. The special mechanism design makes this inclinometer have temperature compensation function, and it has a high degree of stability for long-term monitoring. Using the characteristics of optical fibers that can be connected in series, 12-core optical cables can be connected in series up to 24 pieces at the same time. This product has been actually applied in TK77 Baoshan slope sliding monitoring, TK331 fault zone pile foundation multi-degree-of-freedom displacement and other monitoring cases.

  

  Features:

  1. The 12-core optical cable can be connected in series to 24, the construction is fast, and the signal is stable and reliable
  2. Not subject to interference from high-voltage electric and strong electromagnetic waves
  3. Pass the 72-hour temperature effect compensation correction test
