Thermocouple alloy and junction selection
Hirschmann Pressure Transmitter: Match thermocouple type, polarity and extension cable to the controller input. Select protection-tube material and grounded or ungrounded junction for the atmosphere, electrical noise and response required.
Define insertion depth and the mechanical support at the process connection. A temperature stated in a product name needs confirmation for the complete probe assembly, cable transition and continuous duty.
For Hirschmann Pressure Transmitter, send the controller input, required measurement range, accuracy, probe drawing and cable or connector details. Ask for the agreed sensor designation and inspection requirements on the quotation.
Application and reference configuration
Industrial temperature monitoring and furnace control. The final suitability of Hirschmann Pressure Transmitter depends on the assembled equipment and agreed operating conditions.

| High-temperature heat sink + Hirschmann connector | Effective heat isolation to protect electronic components and extend service life | High-temperature working conditions such as high-temperature steam, boilers, heat treatment, metallurgy (max measurable temperature up to several hundred °C) |
Core Definition and Working Principle
Product Definition: It highly integrates a temperature sensor (such as PT100 platinum resistance thermometer), a signal conditioning circuit, and a transmitter module.
Core Function: It is responsible for collecting the temperature of the environment or medium, and accurately converting the weak resistance signal into an industrial standard signal (usually 4-20mA current signal, and some models support RS485 digital signal or 0-10V voltage signal) for transmission to PLC, temperature controllers, or upper computer systems.
Product Structure and Features
The differentiated designs observed in the image correspond to different applicable scenarios:
Probe (Measurement End): A long rod structure made of stainless steel, which directly contacts the measured medium (air, liquid, medium in pipelines). The rod length can be customized according to actual working conditions. Thicker and longer probes are usually suitable for high-temperature, high-pressure, or large-diameter pipeline environments.
Main Body Housing: A precision metal housing that encapsulates the electronic circuit internally, providing waterproof, dustproof, and explosion-proof (for some models) protection.
Interface Module:
Hirschmann Connector: The common right-angle black interface in the image is an industrial standard interface, which facilitates quick wiring and disassembly.
Digital Display Head: The two models on the right are equipped with red LED digital tubes, which can display the current temperature value in real time without the need for additional external instruments, making on-site debugging convenient.
Heat Dissipation/Protection Structure: The rightmost model features a spiral heat sink structure, specially designed for high-temperature environments (such as steam pipelines, furnaces), protecting the rear electronic components from high-temperature damage through the heat dissipation structure.
Key Technical Parameters and Advantages
Sensing Element: Most adopt imported chips (such as the German Heraeus chips marked in the image) to ensure high measurement accuracy and long-term stability.
Measurement Range: Usually covers -50℃ ~ 200℃ (standard type), and can reach above 600℃ for high-temperature models with heat sinks.
Output Signal: Standard 4-20mA 2-wire signal with strong anti-interference ability, suitable for long-distance transmission.
Material: The housing and probe are mostly made of 304 stainless steel, which is corrosion-resistant and high-temperature resistant, suitable for most industrial environments.
Typical Application Scenarios
Industrial Pipelines: Temperature monitoring of steam pipelines, water pipelines, and oil pipelines in the chemical, petroleum, and power industries.
HVAC Systems: Temperature control of air conditioning units, boilers, cold storage, and other environments.
Equipment Matching: As a standard temperature feedback component for heating equipment, reactors, and industrial furnaces.
5. Selection and Usage Suggestions
Order Requirements: When purchasing, it is necessary to clarify the probe length, insertion depth, installation thread specification (such as M20×1.5, G1/2, etc.), output signal type, and maximum withstand temperature.
Selection Notes: If the ambient temperature is too high, be sure to select a special model with a heat sink, otherwise the electronic module is prone to failure due to high temperature, resulting in inaccurate measurement.
