Overview

Our Integrated Temperature Pressure Transmitter is an advanced all-in-one sensing solution engineered for reliable, real-time fluid parameter measurement across diverse industrial operating conditions. Designed exclusively for industrial enterprise users and system integration partners, this transmitter eliminates the inefficiencies of split temperature and pressure sensing devices, delivering synchronized dual-parameter data with exceptional accuracy in a single compact unit.

At its core, the device integrates a high-stability pressure sensing element and a precision temperature probe, housed in a rugged industrial-grade enclosure to withstand vibration, shock, and corrosive media common in heavy-duty applications. Unlike split sensing solutions that require dual installation points, complex wiring, and extra data synchronization processing, our integrated design simplifies deployment, cuts installation and maintenance costs, and minimizes potential leak points in pressurized fluid systems. Whether monitoring hydraulic fluid, process water, gas media, or industrial lubricants, this transmitter delivers consistent, actionable data to support critical process control and operational safety.

Key Benefits

Unmatched Dual-Parameter Measurement Precision

Engineered for rigorous industrial requirements, our integrated temperature and pressure transducer delivers industry-leading accuracy, with typical pressure measurement accuracy up to ±0.2%FS and temperature measurement accuracy up to ±0.3℃, with optional higher precision grades for mission-critical applications. Full-range digital temperature compensation across -20℃ to 80℃ eliminates drift caused by ambient temperature fluctuations, ensuring stable performance even in rapidly changing operating environments.

Rugged Design for Harsh Industrial Environments

Constructed with 316L stainless steel wetted parts and a fully welded hermetic enclosure, the device offers exceptional corrosion, abrasion, and moisture resistance, with IP65/IP67 protection grade options for outdoor and high-humidity applications. It withstands up to 20g mechanical vibration and 50g shock impact, making it suitable for heavy machinery, mobile equipment, and high-pressure process lines. It also features reverse polarity and overvoltage protection, preventing component damage from wiring errors and electrical surges.

Flexible Integration & Cost Efficiency

With multiple standard output options including 2-wire 4~20mA, 3-wire 0~10V, and Modbus-RTU/RS485, the fluid parameter measurement transmitter seamlessly integrates with most existing PLC, SCADA, and industrial control systems, eliminating costly system upgrades. Its compact, space-saving design fits into tight installation points where separate sensors cannot be deployed, reducing piping modifications and installation labor costs for industrial enterprise users.

Superior Long-Term Operational Stability

With a typical long-term stability of ±0.2%FS per year, the device minimizes frequent calibration and maintenance needs, reducing downtime and total cost of ownership over its service life. Each unit undergoes rigorous factory testing and calibration before delivery, ensuring consistent performance for up to 10 years in standard industrial operating conditions.

Industrial Applications

Our Integrated Temperature Pressure Transmitter is a versatile solution trusted by professional industrial operators across multiple sectors:

Hydraulic & Pneumatic System Monitoring: Ideal for monitoring hydraulic oil pressure and temperature in injection molding machines, hydraulic presses, and heavy construction equipment, enabling predictive maintenance and preventing system failures from overpressure or overheating.

Oil & Gas Midstream & Downstream Processing: Used for fluid parameter measurement in pipeline transportation, storage tanks, and refinery process lines, delivering reliable data for custody transfer, process control, and safety monitoring.

Water & Wastewater Treatment: Monitors pressure and temperature of process water, sludge, and chemical dosing media in water treatment plants, supporting accurate process control and environmental regulatory compliance.

HVAC & Commercial Building Automation: Delivers precise data for chilled water, hot water, and refrigerant systems in commercial buildings, optimizing energy efficiency and ensuring stable climate control for large-scale facilities.
