Series PTGD Differential Pressure Piston-Type Gage, Excellent Accuracy and Over-Pressure Ratings

 

DWYER Series PTGD Pressure Piston-Type Gage can be used to measure the pressure drop across filters, strainers, pump performance testing, and heat exchanger pressure drop monitoring. Its simple, rugged design possesses weather and corrosion resistant gage front with a shatter resistant lens. The DWYER Series PTGD Pressure Piston-Type Gage contains a piston-sensing element which provides different differential pressure ranges with full-scale accuracies of ±2%. Constructed with aluminum or 316SS and available with two 1/4″ female NPT end connections, the Series PTGD provides over-range protection rated to 3000 psig (200 bar) or 6000 psig (400 bar) depending on model. Standard models come with in-line connections. Back or bottom connections are also available.

 

Features

• Rugged, weather and corrosion proof design supports use in harsh environments
• Over-protection range depending on model, up to 6000 psig (400 bar) allows high-pressure applications
• Flexibility of connection selection fits the most sophisticated designs
