Integrated Pressure Temperature Transmitter - Efficient Operating Condition Monitoring Solution

In modern industrial automation systems, pressure and temperature are the two core parameters that determine equipment operating status, process efficiency, and safety. Traditional solutions often require separate installation of pressure transmitters and temperature sensors, resulting in complex wiring, increased interfaces, higher leakage risks, and high maintenance costs. As equipment develops toward compactness and intelligence, integrated design has become the trend.

The integrated pressure temperature transmitter (abbreviated as pressure-temperature integrated transmitter) highly integrates two measurement functions into the same probe, saving space and improving system reliability. The series of integrated pressure-temperature products launched by Nexisense, with the glass micro-melting integrated process as the core, combined with high-precision sensing elements and intelligent compensation technology, perform excellently in typical conditions such as hydraulics, pump stations, chemical processes, and heat exchange systems, and have become the preferred reliable solution for many engineering projects.

Why industrial sites increasingly favor integrated pressure-temperature monitoring

Although traditional split-type solutions are mature, they expose many problems in practical applications:

• Dual-probe installation occupies large pipeline space, increasing perforations and sealing points

• Wiring and terminal blocks increase exponentially, resulting in long construction periods and many failure points

• Pressure and temperature measurement points are inconsistent, causing response lag and data correspondence deviation

• Maintenance requires separate disassembly and calibration, resulting in long downtime and high costs

The pressure-temperature integrated transmitter perfectly solves the above pain points through “one probe, dual signal output”. It integrates the temperature sensing element and pressure diaphragm into the same stainless steel probe, ensuring that both measure the same medium point, making the data more representative and synchronous. At the same time, it reduces more than 50% of installation interfaces and wiring workload, with particularly obvious advantages in space-constrained pump stations, compact hydraulic systems, and hot oil circulation devices.

Core Technical Advantages of Nexisense Integrated Pressure-Temperature Transmitter

1. Glass Micro-Melting Integrated Process — Fundamental Guarantee of Structural Safety

The product adopts a high-temperature glass sintering process above 500°C, forming the stainless steel elastic body and pressure interface in one step, achieving a true seamless, no O-ring, no leakage hazard design. This structure eliminates common sealing aging and welding fatigue problems in traditional products from the source, significantly improving corrosion resistance and long-term reliability. The 316L stainless steel material further enhances adaptability to industrial media such as water, oil, weak acids and alkalis.

2. High-Precision Dual Signal Output and Fast Response

The pressure part adopts high-sensitivity silicon piezoresistive or ceramic capacitive elements, with accuracy up to ±0.25%FS ~ ±0.5%FS; the temperature part integrates high-precision platinum resistance or thermocouple elements, with accuracy of ±0.5℃ ~ ±1℃. Both have response times in the millisecond range, ensuring real-time capture of transient operating conditions (such as hydraulic shock, sudden temperature changes).

3. Full Temperature Range Digital Compensation Technology

Built-in high-precision temperature compensation circuit and nonlinearity correction algorithm effectively suppress temperature drift effects and maintain stable and consistent output signals even when the medium temperature fluctuates significantly in the range of -40℃ ~ +120℃ (some models higher). This is especially critical in applications with large seasonal temperature differences, hot oil circulation systems, or outdoor pump stations.

4. Flexible Electrical Output and System Compatibility

Supports dual independent outputs:

• Pressure: 4~20mA, 0~5V, 0~10V, etc.

• Temperature: 4~20mA, Pt100, Pt1000 direct output or converted analog signal

Optional HART protocol or RS485 Modbus for easy access to PLC, DCS or remote monitoring systems. Various electrical interfaces (M12, aviation plug, direct cable outlet, etc.) meet different on-site wiring habits.

The product shell is rugged and durable, with outstanding impact and vibration resistance, protection rating up to IP65/IP67, suitable for industrial environments with strong vibration, humidity and dust.

Application Value in Typical Industrial Scenarios

Hydraulic and Pneumatic Systems

Hydraulic pump stations, injection molding machines, presses and other equipment need to monitor oil pressure and oil temperature simultaneously. The integrated pressure-temperature transmitter is installed at key points in the oil circuit, allowing one measurement to obtain the corresponding pressure-temperature relationship, helping the system achieve over-temperature protection, efficiency optimization and fault warning.

Pump Stations and Water Treatment Systems

Inlet and outlet pressure and medium temperature monitoring in water supply pump stations and sewage treatment stations are crucial. The integrated design reduces pipeline openings and lowers leakage risks; temperature data assists in judging pump efficiency, scaling and energy consumption status, supporting variable frequency energy-saving control.

Chemical and Thermal Processes

In hot oil circulation, steam tracing, reactor jackets and other scenarios, temperature and pressure influence each other. The integrated sensor ensures data synchronization, reduces measurement deviation, and facilitates process optimization and safety interlocking.

Compressors and Refrigeration Equipment

Compressor discharge pressure and temperature monitoring is important for preventing liquid slugging and overheating. The integrated pressure-temperature solution offers fast response and simple installation, and has been successfully applied in multiple industrial compressors.

Significant Benefits in Actual Projects

Feedback from multiple users after using the Nexisense integrated pressure-temperature transmitter:

• Installation man-hours reduced by approximately 40%~60%
