Dwyer Pressure Sensor 629HLP-06-P2-S1 – Accurate and Durable for Industrial Environments

In industrial systems – from HVAC, water treatment, compressed air to chemicals and oil & gas – pressure monitoring is not only a technical requirement but also a critical factor to ensure safety, stable operation, and effective process control.

However, many harsh industrial environments such as high temperatures, high humidity, heavy vibration, or corrosive conditions quickly degrade conventional measuring devices. The optimal solution in these cases is to choose an industrial pressure sensor with high durability and stability – such as the Dwyer 629HLP-06-P2-S1.

1. Introduction to Dwyer Pressure Sensor 629HLP-06-P2-S1

The 629HLP-06-P2-S1 is a model from Dwyer Instruments’ (USA) high-performance pressure sensor Series 629HLP. This product is specifically designed to operate reliably in harsh industrial environments, offering a linear output signal and outstanding overpressure resistance.

2. Key Advantages of 629HLP-06-P2-S1

• High accuracy – up to ±0.5% FS, stable 4–20 mA output signal, easy integration into control systems.

• Durability in harsh environments – 316L stainless steel construction, excellent corrosion and vibration resistance.

• High pressure tolerance – suitable for measuring compressed air, liquids, and steam within a pressure range of 0 to 6 bar (0–87 psi).

• System compatibility – easily integrates into BMS, PLC, SCADA in factories, pump stations, industrial HVAC systems, etc.

• Compact design – easy installation – standard 1/4” NPT connection, common 2-wire electrical output.

4. Typical Industrial Applications

The Dwyer 629HLP-06-P2-S1 pressure sensor is widely trusted in various industrial sectors such as:

• Industrial HVAC systems – monitor chilled water pressure, air ducts, and steam lines.

• Water & wastewater treatment – pressure control in pipelines, pump stations, and filtration systems.

• Energy sector – thermal and solar power – monitor pressure in transmission systems.

• Oil & gas, chemical industry – withstands corrosive and explosive environments.

• Automated manufacturing plants – integrates with SCADA/PLC systems for monitoring and alarms.

5. Installation Guide for 629HLP-06-P2-S1

To ensure long-term accuracy and stable performance, proper installation is essential:

Installation Location

• Choose a location with minimal vibration, away from high heat sources.

• Mount the sensor vertically, with the sensing port facing downward to avoid fluid accumulation (if used for gas).

Signal Wiring

• Use standard 2-wire connection: power supply (+) and 4–20 mA signal (-).

• Use shielded signal cables if electromagnetic interference is present.

Pressure Connection

• Use standard 1/4” NPT threaded pipe – apply PTFE tape to prevent leakage.

• For corrosive media or pulsating pressure, use a snubber or protective diaphragm seal.
