3. KYB-C3 calibration methods and maintenance

Regular calibration and maintenance are necessary measures to ensure the measurement accuracy of the KYB-C3 pressure transmitter：

1.Calibration interval：Calibration is recommended every 12 months, and should be shortened to 6 months under harsh operating conditions.

2.Calibration equipment：A standard pressure source with accuracy 3 times higher than the device under test is required（such as a 0.05 class pressure calibrator）.

3.Calibration steps： ① Zero adjustment：adjust the ZERO potentiometer under atmospheric pressure so that the output is 4mA ② Full-scale adjustment：apply full-scale pressure and adjust the SPAN potentiometer to 20mA ③ Linearity verification：select at least 5 pressure points for verification

4.Maintenance points： • Check seals every month for aging • Clean the pressure port every quarter • Avoid diaphragm damage caused by media crystallization • Storage temperature should be kept within -20~60℃

4. Typical application scenarios and selection recommendations for KYB-C3

The KYB-C3 diffused silicon pressure transmitter is widely used in the following fields：

1.Industrial process control： • Pipeline pressure monitoring in the petrochemical industry • Reactor pressure control in pharmaceutical enterprises • CIP systems in food and beverage production lines

2.Energy and environmental protection： • Negative pressure measurement in boiler furnaces • Pressure monitoring in aeration tanks for wastewater treatment • Pressure protection for compressed air systems

3.Solutions for special requirements： • Explosion-proof applications：Ex d IIC T6 explosion-proof certified models are available • Hygienic applications：3A certified flush diaphragm structure is available • High-temperature media：media temperatures up to 150℃ can be withstood（special configuration required）

5. Frequently Asked Questions（FAQ）

Q1：What is the difference between KYB-C3 and the PT124B-211-600MPa-M20 pressure transmitter？A：KYB-C3 uses diffused silicon technology and is more suitable for conventional pressure measurement；the PT124B series is designed specifically for ultra-high-pressure operating conditions, with a maximum pressure of 600MPa.

Q2：How can I determine whether a model with a remote transmission signal is needed？A：When the measuring point is more than 50 meters away from the control room, or when strong electromagnetic interference exists, it is recommended to choose the KYB-C3-RT model with a remote transmission signal.

Q3：Which is more suitable for alarm control, SMP131-S4M2F2A5DC or KYB-C3？A：The SMP131 series has built-in dual relays and is more suitable for scenarios requiring local alarm control；KYB-C3 focuses more on high-accuracy measurement.
