Temperature & Pressure Sensors for Cooling Water Systems

Product Specifications

Technical details and manufacturing context for Temperature & Pressure Sensors

Definition

Temperature and pressure sensors are critical components in cooling water systems that continuously monitor thermal and pressure conditions to ensure optimal system performance, prevent overheating, detect leaks, and maintain safe operating parameters. They provide real-time data for process control and system protection. These sensors are designed for integration into industrial machinery and equipment, where they serve as part of the monitoring and control infrastructure. The sensors are available with a stainless steel housing, ceramic sensing elements, copper wiring, and epoxy encapsulation, making them suitable for demanding environments. Key parameters include an operating pressure range of 1.0–1.6 MPa, a temperature range of -40 to 85 °C, an accuracy of ±0.5% FS, a supply voltage of 9–36 V DC, and a 4–20 mA output signal. The ingress protection rating is IP65–IP67 (per IEC 60529), and the process connection is G1/2 (per DIN 3852). The sensor material is 316L stainless steel (per ASTM A276), with a response time of ≤10 ms for pressure step changes, and a weight of 0.2–0.5 kg depending on connection type. These specifications are reference values and must be verified with the legal manufacturer or supplier for the specific model and application. The sensors are designed to operate within the specified ranges; operating outside these ranges may degrade accuracy or cause failure. For example, and outside the temperature range sensor accuracy degrades. The sensors are reverse polarity protected and suitable for washdown environments. They are intended for use in cooling water systems, where they provide essential data for process control and system protection. Always consult the manufacturer's documentation for installation, calibration, and maintenance procedures.

Working Principle

Temperature sensors typically use thermocouples, RTDs, or thermistors to convert thermal energy into electrical signals, while pressure sensors employ strain gauges, piezoelectric elements, or capacitive diaphragms to measure force per unit area. Both types transmit signals to control systems for monitoring and regulation. The sensor output is typically a 4–20 mA loop-powered signal, which is widely used in industrial control systems. The sensing elements are housed in a stainless steel body with ceramic components, ensuring durability and corrosion resistance. The sensor's response time for pressure step changes is ≤10 ms, allowing for rapid detection of pressure variations. The electrical interface is two-wire loop powered, simplifying wiring and reducing installation costs. The sensor's accuracy is ±0.5% FS, providing reliable measurements within the specified operating range. The working principle relies on the physical properties of the sensing elements, which change in response to temperature or pressure, and these changes are converted into a standardized electrical signal for further processing.

Frequently Asked Questions

What is the operating pressure range of these sensors?

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

What temperature range can these sensors withstand?

The temperature range is -40 to 85 °C. Outside this range, sensor accuracy degrades. Ensure the sensor is used within this range to maintain performance.

What is the output signal of these sensors?

The output signal is 4–20 mA, two-wire loop powered. This is a standard industrial analog signal that can be interfaced with most control systems.

What is the ingress protection rating?

The ingress protection rating is IP65–IP67, per IEC 60529. This makes the sensors suitable for washdown environments. However, the actual rating may vary by model, so confirm with the supplier.
