1. Introduction

The FRD Sensor HS51 High Precision Differential Pressure Sensor is designed for industrial applications that require stable and accurate differential pressure measurement.

The HS51 combines a high-stability sensing chip with a fully welded stainless steel structure, providing reliable measurement performance while improving resistance to harsh operating conditions.

Its robust construction and stable sensing technology make the HS51 suitable for applications where differential pressure measurement accuracy, long-term stability, and environmental adaptability are important.

The HS51 can be used in industrial pressure monitoring, water pressure measurement, process equipment, automation systems, and other demanding measurement applications.

2. Why Choose This Model?

In practical differential pressure measurement, customers often face problems such as:

• Measurement drift during long-term operation
• Temperature changes affecting measurement stability
• High static pressure causing measurement deviation
• Corrosive media damaging sensing components
• Sensor failure caused by unexpected pressure overload
• Frequent calibration and maintenance requirements

The FRD Sensor HS51 High Precision Differential Pressure Sensor is designed to address these challenges.

1. High-Precision Differential Pressure Measurement

For applications requiring precise pressure difference measurement, even small measurement deviations can affect system control and equipment performance.

The HS51 uses a high-stability sensing core and optimized signal processing to provide reliable differential pressure measurement for demanding applications. The product specification lists accuracy up to ±0.045% F.S.

2. Stable Performance Under Temperature Changes

Temperature variation can influence sensor output and cause measurement drift.

The HS51 incorporates a built-in temperature-sensitive element to improve temperature performance, helping maintain stable measurement results under changing operating conditions.

3. Fully Welded Structure

For industrial applications, sealing reliability is especially important.

The HS51 adopts a fully welded 316L stainless steel structure, providing strong corrosion resistance and reducing potential leakage risks associated with complex sealing structures.

4. Strong Overload Protection

Unexpected pressure overload can damage sensitive sensing components.

The HS51 incorporates overload diaphragm protection and is designed to withstand significant pressure overload, helping improve sensor reliability in demanding operating conditions.

5. Suitable for Demanding Industrial Applications

The HS51 is designed for applications where measurement stability and durability are more important than simply obtaining a basic pressure signal.

Its combination of precision sensing, robust construction, and environmental adaptability makes it suitable for a wide range of industrial measurement systems.

5. FRD Sensor HS51 High Precision Differential Pressure Sensor Measurement Accuracy Troubleshooting Guide

When the FRD Sensor HS51 High Precision Differential Pressure Sensor shows unstable output or measurement deviation, users can follow the troubleshooting steps below.

Step 1: Check the Pressure Connections

Check whether both pressure ports are correctly connected and whether there are any leaks or blockages.

Incorrect pressure transmission can directly affect differential pressure measurement.

Step 2: Check the Actual Pressure Conditions

Confirm that the actual differential pressure and static pressure are within the sensor's applicable range.

Unexpected pressure overload may affect sensing performance.

Step 3: Check Temperature Conditions

Large temperature changes may influence sensor output.

Check whether the sensor is operating under suitable environmental and medium temperature conditions.

Step 4: Check the Sensor Installation

External vibration, mechanical stress, or improper installation may introduce measurement errors.

Make sure the sensor is securely installed and protected from unnecessary mechanical impact.

Step 5: Check the Electrical Connection

If the sensing element is operating normally but the output signal is unstable, inspect:

• Power supply
• Wiring
• Signal connection
• Electrical interference

Step 6: Compare with a Calibrated Reference

If the measurement deviation remains after installation and connection checks, compare the sensor output with a calibrated reference instrument.

If necessary, perform calibration or contact FRD Sensor for technical support.
