Preparation for Calibration
Before starting calibration, ensure you have all necessary equipment, including a Hongguang pressure gauge to be calibrated, a master gauge (reference standard), calibration pump, connecting hoses, and documentation tools. The calibration process can be applied to a variety of gauges, including stainless steel pressure gauges, digital pressure gauges, and pressure transmitters. Follow your company’s safety protocols and confirm the gauge is isolated from any process media and depressurized.
Step-by-Step Guide to Calibrate Your Hongguang Pressure Gauge
- Visual Inspection: Examine your pressure gauge for physical damage, corrosion, leaks, or blockages. For specialized gauges like the ammonia pressure gauge or pressure gauge with diaphragm seal, check seals and wetted parts for wear.
- Connection to Calibration Equipment: Attach the pressure gauge and the master reference gauge to the calibration pump using appropriate fittings and hoses. Ensure a tight, leak-free connection, especially for pressure gauges with electrical contact or digital pressure gauges.
- Pressure Application: Gradually apply pressure in controlled increments. At each test point (e.g., 0%, 25%, 50%, 75%, 100% of full scale), compare readings from your Hongguang pressure gauge with the reference gauge. Record any discrepancies for each pressure value.
- Adjustment: If necessary, adjust the pressure gauge using the calibration screw or adjustment knob. For digital pressure gauges or pressure transmitters, adjustments may be made via software or control interface.
- Repeat and Verify: Repeat the calibration process in both increasing and decreasing pressure cycles to check for hysteresis. Verify that the pressure gauge performs consistently across the entire range.
Calibrating Specific Hongguang Products
Stainless Steel Pressure Gauge
Stainless steel pressure gauges by Hongguang are designed for corrosive environments. During calibration, extra attention should be paid to the condition of the wetted parts and seals, ensuring there is no contamination or corrosion that could affect readings.

Pressure Gauge with Diaphragm Seal
This type of gauge isolates the sensing element from the process media. Make sure to remove any trapped air or fluid in the system before calibration to avoid false readings. Hongguang’s diaphragm-sealed gauges are built for reliability, but periodic checks are essential.
Digital Pressure Gauge
Digital pressure gauges are straightforward to calibrate using their interface. Follow the manufacturer’s instructions for zeroing and span adjustment. Hongguang digital pressure gauges offer clear menus to simplify calibration procedures.
Ammonia Pressure Gauge
Ammonia is highly corrosive, and Hongguang ammonia pressure gauges are built with special materials. When calibrating, ensure all seals are intact and the gauge is thoroughly cleaned after exposure to ammonia.
Pressure Transmitter
Pressure transmitters convert gauge pressure to an electronic signal. Calibrating these involves both mechanical adjustment and electrical signal verification. Hongguang transmitters support both analog (4-20mA) and digital protocols.
Recommended Calibration Intervals
Hongguang recommends the following general intervals for pressure gauge calibration:
- Every 6 months for industrial pressure gauges and pressure transmitters used in critical applications
- Annually for stainless steel pressure gauges, water pressure gauges, and vacuum pressure gauges in non-critical environments
- Before and after major process changes or after repairs
Common Calibration Issues and Solutions
- Gauge Drift: Occurs when readings gradually deviate over time. Regular calibration of your Hongguang pressure gauge minimizes this issue.
- Mechanical Wear: Continuous use, especially in industrial pressure gauges, can lead to wear. Inspect and replace as needed.
- Electrical Errors: For digital pressure gauges and pressure gauges with electrical contact, verify wiring and signal output as part of the calibration routine.
- Seal Failure: Diaphragm seals or ammonia-specific gauges require frequent inspection for leaks or degradation.
Documenting Your Calibration
Recording calibration data ensures traceability and compliance with industry standards. For each Hongguang pressure gauge, document:
- Serial number and model (e.g., stainless steel pressure gauge, digital pressure gauge)
- Calibration date and technician details
- Environmental conditions
- Test points and discrepancies
- Adjustments made
- Next scheduled calibration date
