In industrial automation control systems, CLG-D and PX-BACHX pressure transmitters, as two mainstream diffused silicon pressure sensors, have alarm control and remote signal transmission functions whose selection directly affects system stability. This article will provide professional selection recommendations for technical evaluators from the perspectives of technical parameters, installation methods (such as BP-H pressure transmitter installation instructions), and maintenance (with reference to MBS4701-060G5811 standards).

I. Technical Parameter Comparison: Core Differences Between Alarm Control and Remote Signal Transmission

The CLG-D pressure transmitter uses a diffused silicon liquid and gas pressure sensor with alarm control function, and its built-in dual relay output can achieve high and low limit alarms (refer to DG1300-PJ-1-CJ/GK/GK pressure transmitter technical specifications), while the PX-BACHX model realizes remote signal transmission through the 4-20mA+HART protocol, complying with the industrial communication standards of the FST800-211P341I-10B pressure transmitter. Measured data shows:

II. Key Points for Installation and Maintenance

According to the KYB-C1 pressure transmitter installation instructions, both models require attention to the following items:

• During pipeline installation, an isolation diaphragm must be used to protect the sensor (refer to JM-2010-5M pressure transmitter installation specifications)
• Electrical connections must comply with the shielded cable standards required by the CR-YM2 pressure transmitter
• Regular calibration should be carried out according to the interface dimensions indicated in the MPM489E22B1C2G pressure transmitter dimensional drawing

It is worth noting that the domestic weighing sensor H3-C3 tension and compression S-type stainless steel weighing sensor can form a complementary solution with pressure transmitters in force measurement scenarios, and its ±0.02% comprehensive accuracy and operating temperature range of -20℃~+65℃ are particularly suitable for harsh working conditions.

III. Selection Decision Tree: 5 Key Evaluation Dimensions

Technical evaluators should give priority to the following considerations:

1. System architecture: For DCS systems, PX-BACHX remote signal transmission is preferred, while PLC local control requires the alarm contacts of CLG-D
2. Safety level: The relay output of CLG-D can directly cut off hazardous sources, meeting SIL2 certification requirements
3. Maintenance cost: PX-BACHX supports HART protocol remote diagnostics, reducing on-site maintenance frequency
4. Environmental adaptability: The wide temperature range characteristics of CLG-D are more suitable for high-temperature scenarios such as metallurgy
5. Expansion requirements: PX-BACHX can realize multi-node monitoring through bus expansion modules

IV. In-Depth Analysis of Industry Application Scenarios

In the petrochemical field, the PX-BACHX pressure transmitter, by virtue of its remote signal transmission function, can perfectly match the explosion-proof requirements in the BP-H pressure transmitter installation instructions; while the food and pharmaceutical industries favor the hygienic design of CLG-D more, and its fast alarm response can effectively prevent cross-contamination. It is worth noting that when high-precision devices similar to the H3-C3 weighing sensor are combined with pressure transmitters to form a composite measurement system, special attention must be paid to signal interference issues.
