The Hirschmann pressure transmitter is an industrial pressure sensor using a Hirschmann connector. It detects pressure through a diffused silicon or ceramic core and outputs a standard 4-20mA signal. It is widely used in liquid and gas pressure measurement and control in industries such as petroleum, chemical, and power.

Core Technology and Specifications: The core performance of the Hirschmann pressure transmitter is based on the following technical specifications:
Measuring Range: Covers 0-0.5MPa to 0-70MPa, supporting gauge pressure, absolute pressure, and differential pressure modes.
Output Signal: Standard 4-20mA two-wire output, compatible with HART protocol; some models support 0-10V or RS485 digital output.
Accuracy Class: Mainstream accuracy is 0.5%FS, high-precision models can reach 0.2%FS, using micro-fusion technology to improve stability.

Environmental Adaptability:
Operating Temperature: -20℃ to 80℃; customized heat dissipation solutions are required for high-temperature environments. Protection Rating: IP65/IP67, 316L stainless steel casing for corrosion resistance.
Overload Capacity: Supports 1.5-2 times full-scale pressure surge.
Application Scenarios and Features
Industrial Sector:
Petrochemical: Used for pipeline pressure monitoring, resistant to corrosive media such as oil and acid.
Power Systems: Integrated into boilers and hydraulic equipment for constant pressure control.
Environmental Monitoring: Suitable for water treatment and weather stations, measuring wind pressure and vacuum negative pressure.

Core Advantages:
Compact Design: Small size (e.g., 20mm diameter Hirschmann connector), suitable for installation in confined spaces.
Intelligent Display: Some models are equipped with an LCD digital display, supporting on-site button zeroing and full-scale calibration.
Ease of Maintenance: Hirschmann connectors allow for quick insertion and removal, reducing downtime.
