4. Key Benefits of the 629C-05-CH-P2-E5-S1

• High accuracy with stable signal
  Uses advanced microprocessor technology with ±0.5% full-scale accuracy – ensuring precise and stable output over time.
   

• Industry-standard signal output
  4–20 mA (2-wire) signal supports long-distance transmission with excellent noise resistance – ideal for factories and high-rise buildings.
   

• Durable and corrosion-resistant construction
  All wetted parts made of 316L stainless steel – resistant to corrosion in water, compressed air, and mild chemical environments.
   

• Flexible installation
  Equipped with a 1/4" NPT threaded port – compatible with most pipe systems. Compact size makes it easy to mount in control panels.
   

• High reliability – 24/7 operation
  With an industrial-grade IP65 design, the sensor can operate continuously in harsh environments with minimal maintenance required.
   

5. Installation Guide for 629C-05-CH-P2-E5-S1 Pressure Sensor

• Step 1: Prepare for installation
  Identify the pressure measurement point: on a water pipe, compressed air line, or storage tank
  Shut down the system and release pressure before installing or removing the sensor
   

• Step 2: Mechanical connection
  Thread the sensor into the measurement point using 1/4" NPT threads
  Use PTFE tape to ensure airtight and watertight sealing
   

• Step 3: Signal wiring
  2-wire connection: one for power, one for signal
  Connect to the controller or PLC according to standard wiring diagrams
   

• Step 4: Configuration and calibration (if required)
  If high-precision measurement is needed, calibrate the sensor using certified industrial calibration tools or a reference device
