Key Benefits

High-Precision Dual-Channel Parallel Measurement

This 4-20mA dual channel pressure temperature sensor supports independent parallel measurement of pressure and temperature, with a temperature sensor positioned in close proximity to the measured medium to minimize transmission errors. It delivers a standard pressure accuracy of ±0.5%FS (optional ±0.2%FS) and temperature accuracy of ±0.4℃, with customizable measuring ranges to meet diverse industrial requirements.

Robust Performance for Harsh Industrial Conditions

Engineered for demanding industrial settings, this transmitter features an IP65 protection grade, superior vibration resistance (20g, 20~5000Hz) and shock resistance (20g, 11ms). It comes with built-in reverse polarity protection, high insulation resistance (>100MΩ at 500VDC), and strong dielectric strength, ensuring stable operation even in electrically noisy or mechanically challenging environments.

Flexible Power Supply & Intuitive On-Site Display

The industrial pressure temperature transmitter with LED display supports multiple power supply options: 3.18VDC (built-in 3.6V lithium battery), 5VDC external power, and 24VDC (930VDC) external power, adapting to various on-site power configurations. Its large dual-row LED display delivers clear, easy-to-read data even in low-light industrial environments, enabling instant on-site parameter checks without additional tools.

Industrial Applications

The 2-Channel Temperature Pressure Transmitter is a versatile solution widely adopted across core industrial sectors where simultaneous fluid pressure and temperature monitoring is critical. It is ideal for industrial process control systems, hydraulic and pneumatic systems, water treatment and environmental protection projects, oil and gas pipeline monitoring, HVAC&R systems, food and beverage processing, and pharmaceutical manufacturing lines.

For process control engineers and industrial operators, this integrated transmitter simplifies multi-parameter monitoring, reduces equipment installation and maintenance costs, and improves the stability and safety of production processes. Its ability to operate reliably across a wide medium temperature range (-40~100℃) makes it suitable for both normal and extreme working conditions in industrial facilities.
