OT-500 Pressure Transmitter Specifications Explained in Detail: How to Match Your Operating Condition Requirements?

As a core component in industrial flow control, the specifications and parameters of the OT-500 pressure transmitter directly affect system stability. This article provides a detailed explanation of the technical performance, installation points, and selection comparison of diffused silicon liquid and gas pressure sensors, helping contract executors accurately match operating condition requirements and avoid procurement risks.

I. Analysis of the Core Performance of Diffused Silicon Pressure Sensors

Diffused silicon technology, due to its excellent stability and sensitivity, has become the preferred sensing solution for pressure transmitters such as HT-S and YMWIDEPLUS-8. Taking OT-500 as an example, its core advantages are reflected in:

• Temperature Adaptability: The operating range covers -20℃~120℃, meeting the measurement requirements of models such as SWP-T20J in extreme environments
• Diverse Signal Outputs: Supports 0~10V/4~20mA output, compatible with mainstream control systems for models such as PT500-503
• Linearity Accuracy: Linear error of less than 1%, superior to the industry standard of similar products such as HY-HY201

It is worth noting that LDN-LDN500 adopts a special packaging process, and its vibration resistance is improved by 40% compared with conventional models, making it particularly suitable for dynamic pressure monitoring scenarios such as oil pipelines.

II. Key Parameters and Operating Condition Matching Guide

When selecting a model, contract executors should focus on the following parameter comparisons:

For scenarios requiring simultaneous monitoring of displacement changes, it can be used together with the domestic displacement sensor JWY-DG. Its differential structure enables μ-level precision measurement, making it especially suitable for composite parameter monitoring systems such as tension and liquid level.

III. Installation Specifications and Fault Prevention

According to the GB/T 34036-2017 standard, the following should be noted when installing diffused silicon pressure sensors:

1. Avoid installation at pipeline bends, and the distance from valves should be greater than 5 times the pipe diameter
2. Vertical installation is recommended for gas measurement, while for liquid measurement the diaphragm should face downward
3. When using PTFE sealing gaskets, the torque must not exceed 15N·m (refer to the dimensional drawing of LDN-LDN210)

Field data from Xi'an Shenghongchuang Instrumentation Co., Ltd. show that 90% of PT500-503 sensor failures are caused by medium crystallization blockage due to improper installation positions.

IV. Illustrated Selection Decision Flow

To help contract executors make quick decisions, we have summarized the selection logic:

Step One: Confirm the medium type (corrosive/non-corrosive)→Step Two: Determine the pressure range (refer to the OT-500 specification)→Step Three: Select the output signal (match the existing control system)→Step Four: Evaluate the ambient temperature (-20℃~120℃ is optimal)

For complex operating conditions, it is recommended to use the JWY-DG displacement sensor for multi-parameter coordinated monitoring. Its spring-type inductive structure can effectively compensate for measurement errors caused by mechanical vibration.

V. Verified Industry Application Cases

In a chemical plant project in Shaanxi, comparative testing between OT-500 and HY-HY201 showed:

• Chlorine pipeline pressure monitoring: the long-term drift of OT-500 is only 0.02%/year, better than the industry standard requirement of 0.1%
• In an 80℃ saturated steam environment, the signal stability of SWP-T20J is 35% higher than that of traditional models
• After being used together with a displacement sensor, the system false alarm rate decreased by 62%
