Pressure/Temperature Sensors for In-line Separation Units

Product Specifications

Technical details and manufacturing context for Pressure/Temperature Sensors

Definition

These dual-function sensors are installed in the In-line Separation Unit to provide real-time monitoring of both pressure and temperature parameters. They are critical for maintaining optimal separation efficiency, ensuring process stability, and preventing equipment damage by detecting abnormal conditions in the fluid flow. The sensors combine pressure and temperature sensing elements in a single housing, typically using stainless steel for the housing, ceramic for the sensing elements, and copper for internal wiring. Pressure sensing commonly employs piezoelectric or strain gauge technology to convert mechanical pressure into electrical signals, while temperature sensing uses thermocouples, RTDs, or thermistors to measure thermal changes. Both measurements are transmitted to the unit's control system for processing and display. The sensors are designed for a range of operating conditions, with an operating pressure range of 1.0–1.6 MPa and an operating temperature range of -40 to 85 °C. Pressure accuracy is ±0.5% FS (per IEC 60770), and temperature accuracy is ±0.5 °C (Class A per IEC 60751). The supply voltage is 9–36 V DC, with a 4–20 mA two-wire loop-powered output (per IEC 60381). Ingress protection is rated IP65–IP67 (per IEC 60529), and the process connection is G1/2 to G1 inch (per DIN 3852). The sensor material is 316L stainless steel (per ASTM A276), and the response time is ≤10 ms for 63% of a step change. Weight ranges from 0.2 to 0.5 kg depending on connection and options. All specifications are reference values; verify model-specific details with the manufacturer.

Working Principle

Pressure sensing typically uses piezoelectric or strain gauge technology to convert mechanical pressure into electrical signals, while temperature sensing employs thermocouples, RTDs, or thermistors to measure thermal changes. Both measurements are integrated into a single housing with separate sensing elements that transmit data to the unit's control system.

Frequently Asked Questions

What is the operating pressure range of these sensors?

The operating pressure range is 1.0–1.6 MPa. Always confirm the exact range for your specific model.

What is the temperature accuracy?

The temperature accuracy is ±0.5 °C, with a Class A tolerance per IEC 60751. This applies within the operating temperature range of -40 to 85 °C. Exceeding this range may damage the sensing element.

What output signal does the sensor provide?

The sensor provides a 4–20 mA two-wire loop-powered output, per IEC 60381. This is a standard analog signal for process control. The supply voltage is 9–36 V DC, with reverse polarity protection.

What is the ingress protection rating?

The ingress protection rating is IP65–IP67, per IEC 60529. This makes the sensor suitable for outdoor or washdown environments. However, the actual rating may vary with the process connection and options; verify with the manufacturer.
