In the field of industrial automation, the selection of the CZL-3 column-type force sensor directly affects equipment service life and measurement accuracy. As a professional supplier of flow control equipment, Xi'an Shenghongchuang Instrumentation reveals 5 key purchasing factors for you, helping technical evaluators avoid common usage misunderstandings of sensors such as ET-2 and CKY-118, and ensuring accurate and reliable tension and compression force measurement in scenarios such as reactors and mixing stations.

I. Material and Structural Design: Determining the Core Durability of the Sensor

The material selection of column-type force sensors directly affects their fatigue resistance and environmental adaptability. Taking the CZL-3 model as an example, its high-strength alloy steel material undergoes a special heat treatment process and can withstand frequent tension and compression cyclic loads in reactor mixing stations. In contrast, some low-cost models such as ET-2 or CKY-118 may use ordinary carbon steel, which is prone to stress cracks after long-term use in corrosive environments.

The following aspects of structural design require special attention:

• Column wall thickness: It is recommended to be no less than 12mm, ensuring structural stability in large-tonnage application scenarios such as XL-G2
• Sealing grade: IP67 and above can prevent dust and liquid intrusion (refer to the military-grade sealing design of NR-LB2)
• Overload protection: The 150% safe overload capacity of the BLR-ZSA model can effectively avoid sudden impact damage

II. Accuracy Class and Temperature Compensation: Dual Assurance for Measurement Reliability

In precision industrial scenarios such as reactors, the 0.1%FS accuracy of models such as YY-L103 may not meet requirements. The CZL-3 sensor adopts the following technologies to ensure measurement stability:

Special reminder: In environments with large temperature differences such as mixing stations, models such as LK-1016 with automatic compensation across the full temperature range must be selected.

III. Installation Method and Mechanical Compatibility

Actual cases show that about 35% of sensor failures result from improper installation. The universal joint installation design of the EX302B model can effectively solve the following problems:

1. Impact of eccentric load

When the deviation between the force axis and the sensor centerline is >1°, the spherical load-bearing design of CZL-3 can control the measurement error within 0.5%, while the traditional flat contact design (such as XL-G2) may produce an error of more than 2%.

2. Adaptability to vibration environments

For high-frequency vibration scenarios in reactors, the damping structure of the NR-LB2 model is worth referencing, as it can attenuate vibration interference above 60Hz.

IV. Signal Output and System Integration

Modern industrial sites usually need to connect sensors such as BLR-ZSA to PLC systems, and the following points should be noted at this time:

• Output type: CZL-3 provides dual outputs of 4-20mA/0-10V, which is more flexible than the single output of ET-2
• EMC protection: The Class III electromagnetic compatibility design of YY-L103 can pass the 500V burst group test
• Protocol compatibility: The CHLET-1 model supporting Modbus RTU is easier to integrate into intelligent control systems

V. Environmental Protection and Maintenance Convenience

In harsh environments such as chemical mixing stations, the following features of the CKY-118 model are particularly important:

1. Surface treatment: Electrophoretic coating + Teflon coating (acid and alkali resistance grade PH2-12)
2. Cable connector: The M12×1 aviation plug is easier to maintain than the direct cable outlet of EX302B
3. Self-diagnosis function: The LED status indicator of CZL-3 can display overload/open-circuit faults in real time
