The Series PTGB Differential Pressure Piston-Type Gage is a low cost differential pressure gage used to measure the pressure drop across filters, strainers, pump performance testing, and heat exchanger pressure drop monitoring. Its simple, rugged and compact design possesses a weather and corrosion resistant gage front with a shatter resistant lens. The Series PTGB contains a piston-sensing element, which provides differential pressure ranges from 0-10 psid to 0-110 psid with accuracies of ±3-2-3%. Constructed from aluminum or 316 stainless steel and available with two 1/4" female NPT back or end connections, the Series PTGB is cost-effective and accurate in monitoring differential pressure.
