Product Advantages and Applications

Technical Features

Using a 316L stainless steel isolation diaphragm and a fully welded structure，the HR-M21KF2AA3 pressure transmitter provides excellent shock and vibration resistance。The built-in temperature compensation circuit effectively eliminates the impact of ambient temperature changes on measurement accuracy，with long-term stability up to ±0.1%/year。

Typical Application Scenarios

• Pressure monitoring in industrial hydraulic systems
• Air compressor outlet pressure detection
• Pipeline pressure measurement in the petrochemical industry
• Hydraulic systems for construction machinery

Installation and Maintenance

The standard G1/2" threaded connection supports direct installation，and a vibration-damping bracket is recommended in vibrating environments。The product has passed EMC anti-interference testing，and can maintain stable output even in strong electromagnetic environments。Zero-point calibration is recommended every 12 months，and dedicated calibration equipment is required during operation。
