What is a hammer union pressure sensor？

A hammer union pressure sensor, also known as an HU pressure sensor, is a specialized instrument used in the oil and gas industry to measure and monitor the pressure of fluids in high-pressure piping systems. It is designed to withstand extreme pressure, shock, and vibration, making it suitable for use in rugged and harsh environments.

Technical Parameters:

1. Pressure Range: The pressure range of hammer union pressure sensors can vary depending on the specific model, but typically ranges from 0-20,000 PSI.
2. Accuracy: Most HU pressure sensors have a high accuracy of ±0.5% full-scale output.
3. Temperature Range: The temperature range can also vary, but most HU pressure sensors can operate in temperatures ranging from -40°C to 85°C (-40°F to 185°F).
4. Output Signal: The sensors provide a linear voltage or current output signal, such as 4-20mA or 0-5V.
5. Material: Made of high-quality stainless steel, HU pressure sensors have excellent durability and resistance to corrosion.
6. Electrical connection: Most hammer union pressure sensors have a 4-pin binder connector or custom electrical connection for easy and reliable connection to external devices.
7. Ingress Protection (IP) Rating: HU pressure sensors typically have a high IP rating, ranging from IP65 to IP68, making them suitable for use in harsh and hazardous environments.

Production Characteristics:

1. Robust Design: As mentioned earlier, HU pressure sensors are designed to withstand harsh environments and extreme conditions. They have a compact and robust design with a thick diaphragm and heavy-duty metal construction.

Q&A:

Q: What is the purpose of a hammer union pressure sensor?

A: The main purpose of an HU pressure sensor is to measure and monitor the pressure of fluids in high-pressure piping systems, primarily in the oil and gas industry.

Q: How does an HU pressure sensor work?

A: The HU pressure sensor has a thin diaphragm that bends under the pressure of the fluid. This bending is converted into an electrical signal by a sensing element, typically a piezoresistive strain gauge, and then amplified to produce an output signal.

Q: What applications are HU pressure sensors commonly used in?

A: HU pressure sensors are most commonly used in drilling, well completion, and fracking operations in the oil and gas industry. They are also used in other high-pressure applications, such as hydraulic systems, pressure vessels, and pipelines.

Q: Are HU pressure sensors suitable for use in hazardous environments?

A: Yes, HU pressure sensors have a high IP rating and are designed to operate in harsh and hazardous environments, making them suitable for use in the oil and gas industry.

Q: How do HU pressure sensors differ from other pressure sensors?

A: Unlike other pressure sensors, HU pressure sensors have a hammer union connection, making them ideal for use in high-pressure applications. They also have a robust design to withstand harsh environments and high pressures.

With their high accuracy, durability, and versatility, hammer union pressure sensors play a crucial role in ensuring safe and efficient operations in the oil and gas industry. Their ability to withstand extreme pressure, shock, and vibration makes them a reliable choice for a variety of high-pressure applications.
