Dwyer Series PTGA & PTGC Differential Pressure Piston-Type Gage

Over Pressure Rating to 5000 psig
differential pressure piston type gageThe Series PTGA and PTGC Differential Pressure Piston-Type Gages 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 a weather and corrosion resistant gage front with a shatter resistant lens. The Series PTGA and PTGC contain a piston-sensing element, which provides differential pressure ranges from 0-10 psid through 0-400 psid. Constructed from aluminum or 316 Stainless Steel and available with two 1/4" female NPT end connections, the gages provides over range protection rated to 5000 psig (340 bar).
