The selection of diffused silicon Hirschmann pressure sensors troubles many users, especially for special models such as DG1300-PJ-1-2-40-CJ-GK-GZ. As the core component of flow control equipment, correct selection directly affects system performance. This article will explain in detail the working principle, model differences, and selection points of diffused silicon Hirschmann pressure sensors, helping operators choose the most suitable sensor solution based on the characteristics of different models such as JP-40B and PT124B-210.

Working Principle of Diffused Silicon Hirschmann Pressure Sensors

Diffused silicon Hirschmann pressure sensors use the piezoresistive effect of semiconductor silicon materials. When external pressure acts on the sensor, the silicon diaphragm deforms, causing its resistance value to change. Through a Wheatstone bridge, the resistance change is converted into an electrical signal output, thereby enabling precise pressure measurement. This type of sensor features fast response, high accuracy, and good stability, and is widely used in industrial fields such as petroleum, chemical, and electric power.

For models such as XMLK-C21, the working principle is similar, but different packaging forms and signal processing circuits may be used. For example, Domestic general-purpose pressure transmitter FD80A hydraulic oil pressure pneumatic sensor adopts advanced temperature compensation technology in signal processing, ensuring stable output within the wide temperature range of -40～+400℃.

Unique Advantages of Hirschmann Connector Connection

The Hirschmann connector is one of the key components of diffused silicon pressure sensors. Its waterproof, dustproof, and vibration-resistant characteristics ensure the stability of signal transmission. Taking the DG1300-PJ-1-2-40-CJ-GK-GZ model as an example, its Hirschmann connector adopts a special sealing design, making it suitable for harsh industrial environments. In comparison, models such as JP-40A and JP-40B may use different connection methods, and users need to choose according to actual application scenarios.

Analysis of Diffused Silicon Hirschmann Pressure Sensor Models

There are many common diffused silicon Hirschmann pressure sensor models on the market, such as PT-PT3002, SST-SST2002, and PH-PH101, and each model has its own unique parameters and application range. The following is a comparison of the key characteristics of common models:

For users who need customized solutions, models such as EJYB-GP-13 support special parameter customization, including pressure interfaces and electrical connection methods. The FD80A series provides multiple measuring range options from 0.6MPa to 2.5MPa, meeting different pressure measurement requirements.

Key Points for Selecting Diffused Silicon Hirschmann Pressure Sensors

1. Matching of Measured Medium and Material

When selecting a sensor, the characteristics of the measured medium should be considered first. For corrosive media, sensors made of 316L stainless steel should be selected, such as the FD80A series. For high-temperature media, products with a wide compensated temperature range should be selected to ensure that measurement accuracy is not affected by temperature.

2. Pressure Range and Overload Capacity

Select a sensor with an appropriate measuring range according to the maximum working pressure of the system. It is generally recommended that the working pressure be within 60%-80% of the sensor's measuring range. At the same time, overload pressure requirements should be considered. Industrial-grade pressure transmitters can usually withstand overload pressure up to twice their full scale.

3. Output Signal and System Compatibility

Common output signals include 4-20mA, 0-5V, and 0-10V, which need to match the control system. For example, the JP-40B pressure transmitter usually provides a 4-20mA output, making it suitable for industrial automation control systems.

4. Installation Method and Electrical Connection

Choose threaded installation or flange installation according to on-site installation conditions. In terms of electrical connection, the Hirschmann connector is suitable for most industrial applications, while aviation plugs are more suitable for vibration environments. FD80A provides multiple optional connection methods to meet different installation requirements.

Summary and Purchasing Recommendations

The selection of diffused silicon Hirschmann pressure sensors is a systematic engineering task that requires comprehensive consideration of factors such as the measured medium, pressure range, and environmental conditions.
