| Feature: |
| The Series PTGA Differential Pressure Piston-Type Gage can be used to measure the pressure drop across filters, strainers, pump performance testing, and heat exchanger pressure drop monitoring. It’s simple, rugged design possesses a weather and corrosion resistant gage front with a shatter resistant lens. The Series PTGA contains a piston-sensing element, which provides differential pressure ranges from 0-150 PSID through 0-400 PSID with full-scale accuracies of ±3-2- 3%. Constructed from aluminium or 316 stainless steel and available with two 1/4˝ female NPT end connections, the Series PTGA provides over-range protection rated to 5000 psig (340 bar). |
