( Brand: Dwyer ), ( Manufacturer Part Number: 3001SGT ), ( Part Type: Pressure Switch Gauge )
The 3001SGT Dwyer Photohelic Differential Pressure Switch-Gauge-Transmitter is a versatile and reliable instrument designed for various industrial applications. This device operates on the principle of photoelectric sensing, which provides accurate and stable pressure measurements in the range of 0 to 1.0 inches of water column (WC).
The 3001SGT features a photocell that emits a beam of light across a sensing chamber. When the process fluid enters the chamber, it alters the beam's path, which is detected by a photodetector. This change in light beam path is used to calculate and display the differential pressure.
The device comes equipped with a built-in gauge and a 4-20mA output for transmitter applications. The gauge provides a local, easy-to-read pressure indication, while the 4-20mA output allows for remote monitoring and control. The transmitter output can be easily integrated into PLCs, DCS, and other control systems for more advanced applications.
The 3001SGT is constructed from high-quality materials to ensure durability and long-term performance. It features a stainless steel housing that is resistant to corrosion and provides excellent protection against harsh environmental conditions. The device's operating temperature range is from -40 C to 125 C (-40 F to 257 F), making it suitable for a wide range of applications.
The 3001SGT is also designed for easy installation and maintenance. It features a threaded connection for quick and secure installation, and the photocell can be easily replaced if necessary. The device is also equipped with a diaphragm seal, which makes it leak-proof and reduces maintenance requirements.
In summary, the 3001SGT Dwyer Photohelic Differential Pressure Switch-Gauge-Transmitter is a high-performance and reliable instrument that provides accurate pressure measurements in various industrial applications. Its photocell-based sensing technology, built-in gauge, and 4-20mA output transmitter make it a versatile tool for a wide range of applications. Its durable construction, easy installation, and low maintenance requirements make it a cost-effective solution for industrial pressure measurement needs.
