Solving Pressure Challenges in Heat Exchangers with PCM303D Technology

In modern industrial processes, heat exchangers play a crucial role in efficiently transferring heat from one fluid to another without direct contact. To maintain optimal performance, safety, and longevity of these systems, reliable pressure monitoring is essential. Pressure sensors and transmitters must withstand demanding conditions, including high temperatures, aggressive media, and vibration, while ensuring consistent and accurate output. The PCM303D pressure transmitter from WTsensor has been engineered precisely for such challenges, offering robust performance, versatile configuration options, and exceptional reliability across a range of heat exchanger applications

✅ Why PCM303D Works Well for Heat Exchangers-Key Technical Highlights

✔ Broad Pressure Range:
Covers from vacuum (-100kPa) up to 100MPa, so you can select an appropriate range based on the system — e.g., cooling water, steam, refrigerant, oil.

✔ High Durability & Resistance:

• Vibration & shock resistant – ideal since many heat exchangers are mounted on vibrating machinery or piping.

• IP65 protection – safe from dust and water jets, suitable for industrial environments.

✔ Good Temperature Tolerance:

• Medium temp up to 105°C is enough for water, oil, or glycol systems.

• If used with steam, consider adding a cooling element (e.g., siphon tube or cooling adapter) to protect the sensor.

✔ Output Signal:

• 4–20mA is standard and reliable for long-distance wiring to PLCs, DCS, or building automation systems.

• Explosion-proof version available if required in hazardous zones.

✔ Compact Design:

• Small, lightweight, easy to install even in tight spots on pipework or exchanger bodies.

  
  

Application on Heat Exchangers

Typical Installation Locations:

· Inlet & Outlet of both shell side and tube side (detect fouling or blockage via differential pressure).

· Can also be used to monitor pump performance feeding the exchanger.
