1.Product Overview
Armored pressure transmitters employ a two-wire transmission method (two wires serving as a common line for power input and signal output), converting thermocouple and RTD signals into a 4-20mA output signal that is linear with the input signal or temperature signal. This enables long-distance transmission of temperature data, precise control, and centralized monitoring.
As a new-generation temperature measurement instrument, it finds extensive application in process control scenarios across industries including metallurgy, petroleum, chemical engineering, power generation, light industry, textiles, food processing, and pharmaceutical manufacturing.
2.Product Advantages
Features a silicone rubber sealing structure, making it shock-resistant, moisture-resistant, and suitable for installation in harsh field environments.
Installed on-site within the junction box of thermocouples or RTDs, it directly outputs 4–20mA. This eliminates the need for costly compensation cables while enhancing signal immunity to interference during long-distance transmission.
The thermocouple temperature transmitter incorporates automatic cold junction compensation.
High accuracy, low power consumption, wide operating temperature range, and stable, reliable performance.
Versatile application: can form an integrated field installation structure with thermocouples or RTDs, or serve as a functional module within detection equipment.
Multiple communication options available, supporting LoRaWAN, NB-IoT, 4G, RS485, 4-20mA, and other protocols.
Supports Modbus and HART communication protocols for seamless integration with PLC, DCS, SCADA, and other industrial control systems;
Supports 3.6V battery power supply or external DC 9V~36V power supply;
Temperature measurement accuracy: ±0.1℃ to ±0.5℃, repeatability ≤ 0.1%.
