Product Description
1. Product Introduction

In cleanrooms, HVAC systems, medical equipment, laboratories, semiconductor manufacturing, and industrial ventilation systems, accurate measurement of micro differential pressure is essential for environmental control, airflow management, and equipment operation stability.

The FRD Sensor FD820C Embedded Micro Differential Pressure Transmitter is specifically designed for low differential pressure measurement applications. It adopts high-sensitivity sensing technology and intelligent signal processing algorithms to accurately detect extremely small pressure variations.

In practical applications, factors such as temperature fluctuations, airflow disturbance, long-term operation, and installation conditions may affect micro differential pressure measurement accuracy, resulting in zero-point drift, unstable signals, and measurement deviations.

The FD820C utilizes temperature compensation technology, high-stability sensing components, and a compact embedded structure design to improve measurement stability and environmental adaptability, providing reliable micro differential pressure monitoring solutions for clean environments, HVAC systems, and automation equipment.

2. Why Choose This Model?
  • Addressing Micro-Pressure Drift and Inaccurate Measurement Pain Points: Traditional micro-pressure sensors are prone to zero drift under small ranges, leading to inaccurate cleanroom pressure monitoring. The FD820C features an automatic zero-clearing function and digital temperature non-linear correction technology, fundamentally solving the micro-pressure drift problem and ensuring clean environment compliance.

  • Addressing Complicated Multi-Parameter Monitoring Pain Points: Traditional setups require separate installation of temperature, humidity, and pressure gauges, resulting in cumbersome wiring and high costs. The FD820C supports multi-parameter integration and intuitive display of differential pressure, temperature, and humidity, streamlining field equipment.

  • Addressing Clean Environment Maintenance Difficulties: Aiming at the problem that sterile environments cannot be frequently powered down or disassembled for maintenance, this product supports online load-pressure automatic cleaning, and its tempered glass panel features no dead corners or dust accumulation, greatly reducing maintenance costs and downtime risks.

5. FRD Sensor FD820C Embedded Micro Differential Pressure Transmitter Measurement Accuracy Troubleshooting Guide
  • Zero Drift Troubleshooting: If a minor reading deviation is found in micro-pressure environments, prioritize using the device's automatic zero-clearing or online pressure calibration functions for correction.

  • Pneumatic Sealing Inspection: Check whether the pressure-taking tubing has air leaks, flattening, or blockages to ensure smooth gas entry into the sensor.

  • Power Supply and Signal Interference: Verify whether the input voltage is stable within the 16V~28VDC range (24VDC recommended), and check if signal cables suffer from strong electromagnetic interference.

  • Ambient Temperature Check: Ensure the operating environment temperature is within the 0℃~60℃ specification to prevent extremes from affecting the accuracy of digital temperature compensation.
